Checking out the DR Winter League Ballparks


???????????????????????????????The World Series is not the only pro baseball  going on this weekend.  Its also the start of the 2013 Caribbean Winter League Season.    We started reviewing  the pro parks in the Dominican Republic this past week.  This will be our 3rd series of winter league cub evaluations.    It was great  seeing the progress they are making on the fields.  I recall during our last set of inspections they were needing equipment and materials that was not available on the island.  After seeing just a few of the DR parks this year,  we noticed a marked improvement of the playing surfaces and the facilities.    ( Photo above is Santiago’s ballpark.)

quiesqya( Photo above in Santo Domingo) There are several reasons that I believe relate to the  continuing improvements of the facilities and fields.   MLB OPs  has been hosting field clinics every other year in the DR,  the MLB DR office has expanded and is a huge resource for the clubs as they determine ways to make there parks better.   You also have  clubs that are  devoting more time and funds towards making their parks better for fans and players.      Everyone wins!     6 years ago most of the fields were a bit rough and the ground crews were frustrated with lack of materials and overuse.   Still room for improvement but…There is a new breeze blowing and it’s going in the right direction.   Nice work by the MLB DR office and the WL.  ( La Ramona Ballpark Below)

SCG renovation underway for 2014 MLB opener


20130930-185654.jpg

One end of the pitch is being graded to be more like a baseball infield in preparation for the 2014 MLB opener. They removed about 45000 sq ft of grass and slightly leveled the area where the infield will be placed in front of the new grandstand. The grandstand also had permanent dugouts installed as part of the total renovation. The SCG is not touching the cricket wicket so those hallowed grounds are safe. The SCG crew is awesome. What a great group to work with.image

Haarlemmermeer municipality new baseball field


imageThis  Natural grass baseball field construction  project in the suburbs  of Amsterdam is almost complete.   It was put to the test after a heavy rain storm Monday evening and throughout the entire night.   Overall, It rained several inches Monday and the field was totally dry as we walked across it Monday morning.    The warning track also didn’t have a single puddle.   This field was constructed on a parcel of land that is 5 meters below sea level.    Great job city , architect and contractor.

Checking out Korea’s Baseball Stadiums


korea domed stadiumLast week  I was a guest of the KBO (Korean baseball organization).   In an effort to upgrade their parks now and in the future we visited each stadium and spoke with operators and care takers collecting information about their facilities.   Korea is in the process of renovating and building new parks as the KBO league expands.   All of the ballparks range in size from 10,000 to 28000 capacity.  All of the fields are Kentucky bluegrass or synthetic grass.  A couple stadiums are moving away from synthetic back to natural grass.

jamsil stadium korea olympicsOne of the older stadiums was called Jamsil ballpark.   The ballpark was used as part of the 1988 Olympics.  According to the locals, the two teams that play here are considered the Yankees – red sox of Korea.  I must have heard it 10 times and from the looks of the sellout game I attended, it sure felt like it.  You can draw a line through the center of the stadium between the fans cheering on the bears or the twins.   One of our tasks was to check the lights  and at Jamsil stadium and we were allowed  to perform the light check during the 5th inning.   As with most Asian leagues, after the 5th inning they re-line the field and the umpires take a several minute break.  The players actually go out in the outfield and  stretch again.  That was the first time checking lux levels in front of 27000 people.

mokdong stadium bonsai garden batters eyeFYI – This country is passionate about their baseball.   We had the chance to attend a few games and it was electrifying!  The other thing that struck me was the demographics of who attended the games.  I would estimate, more than half the crowd was between the ages of 18-30.  There was a party in the stands that was choreographed with songs for each player.   The songs played straight through the entire at bat of the home team or visiting team.     Even when the hitter was swinging away!   Something you don’t see in other countries.

Korea’s first domed stadium is underway (top photo) .  Considering the temperatures in March are similar to Detroit , the warm building will be enjoyed by the local communities in the winter time.    It will also make the  fans happy during those hot humid summers with AC.

jamsil stadium crowdThe best part of the Korean ballpark tour was meeting the people and making friends .   A big thanks to the KBO team especially Joey, Sean, Jason and Mr. Haun!  You guys rock!    Sports brings people together and just like baseball in any country our game is a common connector.   Looking forward to the next trip already!

A new stadium in 2014 for the Tomateros de Culiacan


Acceso estadioA new park is underway in Culiacan , mexico.  The future home of the Tomateros is designed to hold 18000 people!     Its a natural grass stadium with some wonderful site lines.  This is going to be a fun project because the city is really cool.   The architect took some time in designing the seating bowl which will generate a lot of fun for fans.   It’s going to truly be a fan friendly facility.    The planned opening is October 2014.

Campo de juegoThe owners of the club are the Ley family.  They are really excited about this new sports venue in their home town and deserve to be. They are a good family with a long history in the Mexico and the baseball community.     The club has a very strong history of winning the Mexican Winter league and has had numerous championships over the years.   This park is being constructed directly beside the current baseball stadium so  logistics will be challenging for the 2013 season but in the end,  they will have new jewel in the Mexican winter  league.   Congrats to Juan Manuel Ley Lopez, his family and the architect Jim Sevilla

Amsterdam’s New Baseball Stadium !


 

amsterdam field 2The blue grass planted only a couple weeks ago is coming up nicely and the ballpark is completing the steel/concrete risers. The city of hoofddorp and the contractor are pushing the bluegrass along for full establishment this fall. The ballpark will end up seating about 500-1000 but will be able to expand to 25000 seats. the project will be completed by November 2013. It will open in the spring for the Pioneers Club team and be used by the Dutch Federation for training their national clubs as well.

Pretty cool ballpark. Kudos to Chad, Kevin, Eric, Isaiah and Anthony.

How to Build a Baseball Infield


infield watered.jpgTechnically, the term infield skin refers to segments of the baseball field that contain clay, specifically the areas around the bases and base paths. The keys to quality infield skin are good materials, proper moisture and consistent maintenance practices. With 70 percent of the game played on the infield, having a consistently firm, smooth playing surface is essential.  The photo above is from a youth league in Taiwan where the kids use water cans to darken the soil in the shape of an infield.  Below – - They mark the field too.  Just awesome!  

Young Taiwan GroundCrew makes it happen!

Infield construction

Infield mixes are made from various combination’s and percentages of sand, silt and clay. People consider the general standard for an OK infield to be 60 to 70 percent sand, 30 percent clay and 10 percent silt. Particle size also makes a big difference in these materials. Infields vary greatly by regional conditions, commercially available mixes and the preferences of the sports field manager and their facility and teams.

The nail drag scarifies the surface and digs deeper to further loosen the infield mix. With any drag, be careful not to drag too close to the turf edge.
Annual laser-grading is used to check the infield slope and correct any inconsistency.

The weight of the infield mix is in the clay and the silt and that’s what retains the moisture. You may be in an area with a lot of rain, and if you don’t have much maintenance help for tarping you’ll want to have a bit sandier infield mix. If you have a heavily used field or one for university or professional play, you’ll probably want a more stable infield with a heavier mix containing more clay and silt to withstand the wear and tear of multiple events. For some infield mixes with lesser percentages of silt and clay, a conditioning amendment of calcined or vitrified clay is worked into the top 1 to 2 inches of the mix to help bind the clay and stabilize the infield.

When constructing a new field or rebuilding an existing one, the general depth of the infield material for the baselines is approximately 5 inches. The depth, the type of material used and the subbase components are subject to budgetary constraints. There are fields with the infield mix placed directly on the subbase soil, some on a sand layer over the subbase soil, some directly on a pea gravel layer and some on geo cloth covering any of these subbases.

Opinions differ on whether a geo cloth layer will be detrimental to drainage. While drainage within the infield mix will vary according to the percentages of clay and silt, it is generally slow, so many prefer the geo layer for other advantages. It can keep pea gravel from migrating up into the infield mix and bordering grassed areas. Geo cloth on the pea gravel does keep the infield mix from sifting into the gravel, reducing the need for continual addition of the mix during the first few years of construction and helping stabilize the surface more quickly.

To counteract slow drainage within the infield mix, many fields are constructed with a slope to help move the surface water off the clay and into the grass. A slope of about .5 percent, extending from the edge of the pitcher’s mound out past the 95 arc should provide sufficient water movement for most fields. Some skinned baseball infields and some softball fields are constructed with a greater percentage of slope.

It’s critical to achieve consistency of slope across the entire surface. Use laser-grading equipment and a skilled operator. Otherwise, once all the material is in place, run string lines from the infield grass to the outfield grass across the infield and work your way across the field with shovels and rakes. Keep moving the string lines every 1 to 2 feet, and check and recheck for accuracy as you move.

Managing moisture

An in-ground irrigation system with a zone that only waters the infield clay is one way to deliver volumes of water quickly. When water patterns are diverted in windy conditions, hand-watering will be required to reach the places missed.

Quick-connect outlets behind the mound and behind home plate provide access to hook up a water hose. Some field managers place quick couplers at the infield corners behind first and third base in the grass. A 1-inch hose is preferred to deliver a larger volume of water faster. A retractable hose reel installed in the ground behind the mound makes pull out and rollback easier and eliminates hauling the hose out and back for each watering.

Select hoses and hand-nozzle sizes based on the number of fields you need to maintain and the size of your crew. Ideally, your nozzle selection should be able to apply enough water to reach the desired depth for the initial soaking and to lightly mist repeatedly to maintain the desired moisture level. Some infields drain so well that you can “puddle” the infield after a night game and it will be perfect for play by morning.

When necessary, crews can level the infield skin using a string line and hand-held tools and hand-pulled drags.

Top it off

Using the different calcined or vitrified clay amendments as the top surface coat can make it a little easier to manage the skin moisture levels and achieve consistency. You don’t want the players to pick up wet clay on their spikes or have the infield get too dry during the pregame workouts. With a topping of 1/8 to .25-inch, you can soak the infield as you would normally and have a good surface for workouts and sufficient moisture retention for the game. Consistency of depth is extremely important during the initial application of the top layer both for accuracy of the slope and footing for the players. Once in place, use a cocoa mat or the back of a fan rake so you’re just lightly smoothing the top surface and not moving piles of material.

Dry down

An infield tarp is an important tool in moisture management. No one likes to use it, but covering the infield when you have rain issues can be the quickest and easiest way to preserve playability.

Edging the infield as a weekly maintenance practice will reduce lips and keep turf edges smooth. This Turfco Edge-R-Rite was used in 2004 during the Olympics. Along with edging the bermudagrass, it doubled as a small sod cutter.
Rolling infields is an important practice to stabilize the areas.

The worst thing you can do following a heavy rain on an uncovered field is to work the field too early. Let the sun do its work on the dry down before you get out there to squeegee, rake and dig. The dryer subsurface material will try to draw down the moisture from an undisturbed wet surface. If you must work existing or added material to dry down the surface, use a roller squeegee rather than a rake to spread the water so you’re not cutting into the wet material and disrupting that downward movement.

If you have depressions with standing water, fill them with calcined clay and let it soak up the moisture for 15 to 20 minutes. Then, spread out that moist material to dry further, or borrow a technique from ground crews in South America to remove excess water with no surface penetration. They use a supply of 12-by-24-inch foam-rubber sponges (old padding) and place one in an area of standing water, step down on it, allow it to absorb water to capacity, pick it up, wring it out and use it again.

Another technique to combat light rain or drizzle, and to use between innings when the dirt is starting to look shiny, is to apply a very thin layer of conditioner using a regular walk-behind or hand-held spreader set for the largest opening. You’ll get a more consistent layer than pouring conditioner from the bag or putting out piles to spread.

Working the dirt

The right equipment used properly is critical in maintaining the infield skin. You’ll want a series of different types of drag mats, rigid and flexible steel mats for breaking up dirt clods and leveling, and cocoa mats for finishing the surface. You’ll need both a fine nail and heavy nail drag for scarifying the surface and digging deeper to further loosen the mix and allow better moisture penetration. You’ll need rakes, brooms, edgers and rollers. The 1 or 2-ton roller will become your favorite tool.

The three-wheel field rakes produced by the major equipment suppliers do an excellent job, and they come with an assortment of attachments, as well as connection points for other implements. You also can use a small tractor, lawn mower, utility vehicle or golf cart to pull the drags.

We bored into the infield to check soil conditions and discovered a layering of different clays. We had to rototill to remove the barriers so the clays would not “plate” when the players took the field.

Always pull the bases and insert the plugs so you can drag the entire infield. Pay close attention to the wear areas around and in front of the bases, such as where the first baseman plants his foot. Consider incorporating a heavier clay mix 10 feet out from first base and also at second and third base to make it easier to reduce divoting and keep indentations from forming. Follow different routes when driving equipment onto the field to reduce compaction issues. Transport the drags to the field and drop them at different spots each day. When working the field, keep attachments, drags and screens 6 inches away from the grass at both edges of the base path to avoid lip build up. Use a variety of dragging techniques, continually altering your patterns and incorporating circular spirals and figure eights. Go slow, especially in the turns, to avoid slinging materials.

Managing Lips

To avoid creating lips when hand-raking, always rake up and down the base path, not across it. Work the grass edges with a fan rake or stiff-bristled broom after every practice, workout and game. If you don’t have the staff for that, use the water hose to blast the infield mix from the grass edges at least once a week.

You’ll want to edge the infield grass periodically, cutting away turf to remove any lip buildup, then backfill with new infield mix, tamp down firmly and test the edge. There should be no transition between the grass and the clay. If you can feel even the slightest difference with your foot, the ball can feel it when it hits, and that’s what causes a bad hop.

WBC Workouts for Great Britain & Canada


A great first day for the two clubs at the renovated ball park in Regensburg for the World Baseball Classic.  Field held up great as did the weather.  GB’s Sam Dempster was excited to see the field and the upgrades.  Canada’s Ernie Whitt and Greg Hamilton also had some great things to say about Armin Wolfe Arena grounds.  Always good to get the first day over.  Martin Brunner and his groundcrew did a great job managing the practices.  With 8 practices and only 6 games it sounds a bit upside down but that’s baseball.

GB’s squad actually met yesterday for the first time with the pros that joined them.  i think with the influx of pro guys for Czech, Germany and GB this will be an interesting tournament.  By the way… Thanks to Dan Bonanno and Kevin for painting some awesome logos!   You guys rock!

Ballparks in Regensburg and Athens


On my recent venture we took some time to check in with the folks in regensburg Germany to see how the WBC qualifier preparations were coming along. Stopped in Amsterdam to see the developments of a new ballpark and then onto Athens. The 2004 Olympic baseball stadium in Athens is currently not a baseball venue but a soccer venue. At least they are using it for a outdoor sport!

There is only one “main” olympic stadium still being used for baseball which is in barcelona host of the 1992 games. The 1996 olympic stadium was Fulton county stadium which was torn down,the 2000 olympic main stadium in Sydney was a showground for cattle and was only a temporary venue for the games. However west of Sydney is the 2nd olympic venue and it has been resurrected by mlb and is used in the abl league. The 2008 wukesong baseball olympic stadium in beijing and both Practice fields were reduced to rubble shortly after the games. So the Olympic baseball stadium legacy plan is not doing so great

Baseball Field Maintenance


Thumbnail image for Thumbnail image for york field.JPG

The level of competition and the expectations of your field users dictate the kind of pregame maintenance routine you’ll have. The routine is a short version of your daily and weekly long-term care. It’s an integral part of the multitude of tasks that need to be done prior to a game. The following basic routine is what would take place in typical, sunny weather conditions. Obviously, rain, snow or other disruptive weather would require major adjustments.

The game day maintenance process actually begins the day before, with the focus on putting the field in its best playing condition for the next scheduled game time. The day starts with mowing. Generally, the foul lines are repainted and the coaches’ boxes marked once mowing is completed. Since time will be limited for the pregame prep, water the infield area heavily early in the morning and/or the night before to reach the best amount of moisture by pregame so only a light wet-down is needed prior to game time. You may need to add water throughout the day, depending on the type of infield surface you have. Smooth out the mound and home plate area and cover them again.

 

Whether the field serves recreational or pro-level play, make sure you have the right equipment and tools for the pregame routine in good operating order, staged and ready to go. Develop a checklist. Cover all the details in advance. Put gas in the utility vehicle or field rake; chalk in the chalk box, etc.

This is a highly orchestrated routine, and you are the conductor. Develop a plan; assign specific duties based on the time frame you normally have, and make it consistent. Review all the details, making sure every crew member understands how everything works and knows exactly what to do. Practice to ensure it flows smoothly, striving to make it a little better each time.

Pregame for rec-level baseball

This pregame routine for recreational-level baseball is plotted for a quick 15-minute fix with a two-person crew, designated here asJack” and “Jill.” Jack drags the infield, generally with a cocoa mat, but if the surface is chewed up from practice, using a screen mat. It’s an on-the-spot judgment call, so have both mats staged and ready. Jack pulls the practice bases and inserts the plugs prior to dragging.

Generally, the infield foul lines would already be in place, having been lined out and put down earlier with a chalk marker. If not, Jack will drag the larger infield area, and the lining and chalking will take place as soon as dragging is completed.

Jill starts doing the home plate and mound work. If there’s no hitting mat, Jill will need to do hole repair with packing clay. If a mat was used, Jill just smoothes the area, first using a rake and following with a screen mat or cocoa mat. Jill then sets the batter’s box frame and puts down the chalk.

By now, Jack has finished dragging. He moves on to fix the pitcher’s mound, paint the pitching rubber and home plate and do any needed touch up on the foul lines in the infield area. Jill starts watering the infield, taking care to avoid the foul lines and the grass. Jack comes in to hold the hose once the other tasks are completed.

Jill places a towel (or an old plate) to cover home plate, lightly waters that area and removes the towel. If there are any dirt issues, Jill sweeps it off with a towel and takes a handful of chalk from the chalk box, rubs it into home plate to help dry it and removes excess chalk.

Once the watering is complete, Jill marks the coaches’ boxes if they haven’t been marked previously. Jack sets the bases and does the final inventory to ensure all equipment is off the field and the setup is complete.

Assignments are adjusted for a three or four-person crew. For example, one person will pull the practice base and insert the plug at second and start dragging from second to third base. The third or fourth person will pull the practice bases at first and third, inserting the plugs. Crew members three and four will start the infield wet-down along the third base side, while person one moves on to drag along the first base side.

Pregame for pro-level baseball

At the pro level, in addition to basic pregame maintenance and setup, there’s an entire practice setup and take down. The question to keep asking is, “What else can I do to protect the field and make it better for the game?” The array of tools to accomplish that typically include: the pitching deck and the geotextile turf protector that goes under it, the batting cage, the turf protector for the back that fits around the batting cage and the extensions or separate pieces for the fungo circles, the trapezoid section that goes on the grass in front of home plate, the home plate mat, the protective screens for first and second bases, the ball shagging screen and two ball baskets on wheels.

Take a full inventory of the tools and equipment you have to make sure it’s all staged prior to use and picked up afterward. Each person is responsible for his or her assigned area and they provide the check, down to the tiny details. If they took 32 pins onto the field to anchor a protector, they need to be sure 32 pins came off.

For years, it was the custom in the major and minor leagues to take batting practice first and the infield practice afterward. When batting practice comes first, the setup usually takes about 20 minutes and starts when the team comes out to get loose. Over the past couple of years there’s been a trend for teams to take the infield practice before batting practice. If that’s their preference, you have to prepare to put the batting practice things out there the same way, but very quickly.

Another trend in the MLB is for the visiting team to take infield practice just once while in town and the home team just once during the home stand, generally prior to their first batting practice. For most low-level minor league play, everyone takes infield practice, with each team working for 10 minutes. Pregame practice is always a double cycle; the home team goes first, then the visiting team.

Communication between the head groundskeeper and coaches is key the night before the game to find out the plans for the next day. That may include an early practice, which means a few infielders or pitchers will do some drills prior to the typical batting practice. Some pitchers don’t want to throw off the pitching deck. Bottom line, whatever they want is what you do.

Communication with the front office is essential, too, so you know all the details for the first pitch and pregame ceremony, including the performance of the national anthem. You need to know who will be coming onto which area of the field and when it will take place so you can plug it into your setup schedule. Sometimes you’ll place a fake home plate for the ceremony. Your grounds crew will need to replace it because they know how to walk across home plate, approaching it from behind the catcher’s box to avoid tracking chalk around the batter’s box.

You need a lot of people to accomplish all this, typically five or six people for the minors and eight to 10 for MLB level. In Beijing, I had 14, which was necessary because some of the equipment was so heavy. With the increased numbers, activity and visibility, the orchestration becomes even more important.

T

On a typical practice day, batting practice (BP) comes before infield practice. You’ll have only 2 to 2.5 minutes to remove everything you’ve placed for BP. If your exit for the cage and screens is through the center field gate, you’ll need to take the cage and screens all the way off before infield practice can begin. If the exit is on the first or third base side, you can stage them off the field in foul territory temporarily, and then complete the removal.

Once the practices are completed for both teams, the pregame maintenance and setup begin. The basics are similar to the rec-level pregame routine, with more detail work added. One crew member will be dragging; others will be sweeping up loose clay around the mound and home plate; some will be removing any clay from the grass edge; some will be clearing any debris from the grass off the clay; some will be smoothing the area around the warning track with a fan rake; and one person with a smoothing board, rake or small drag will be working along the edges of the infield. At least four or five people will be holding the hose, with the one at the nozzle being extremely careful to keep any water from falling on the grass. Wet grass, which could result in a wet ball or damp cleats that pick up clay, is unacceptable on a sunny day at this level of play. Some crew members put down fresh chalk on the foul lines.

At all levels, the game bases are set after the watering is completed so they’ll be dry and not slick. For the pros, there’s a specific way of placing them so the logos are set consistently at first and third.

The head groundskeeper makes one final field walk, checking to ensure the setup is complete and no small details have been missed. If there is an issue, it’s fixed immediately and addressed prior to the next pregame setup. The goal is perfection.

Once you establish the most efficient plan, make it so consistent that it becomes routine so you can do it fast enough, but not so routine that you become complacent. If your guard is down, sometimes you forget something.  Above all remember you are part of the “show” and a key member of the team,  therefore presentation and how your staff looks on the field is also very important. Same shirt, cap, pants adds to the professionalism of your crew.  Planning for the unexpected is also important.  Things like irrigation system breaks, the water hose breaks, the cart runs out of gas while dragging the field, a base anchor is bent etc…  Things happen so its best to have a procedure in place to deal with the unexpected.

2012 MLB Dominican League Field Maintenance Clinic


The MLB Dominican League Office in the D.R. hosted the 4th annual MLB Dominican League Field Maintenance Clinic this week at the Cleveland Indians Academy in Boca Chica.   We had a great turnout with about 45+ sportsturf managers and operators representing 26MLB clubs and 5 winter league baseball stadiums.

Also had a couple new guest speakers take part in the education sessions this year.   Trevor Vance Kansas City Royals Head GK, Tom Burns and Rene Asprion with TXI.

The MLB Academy development in the DR has been growing extensively the past 5 years.  Each club has invested in building new and  upgrading existing 2 or 3 field  complexes that sport great fields and facilities for the young athletes.

As a teacher by trade,  it is a wonderful feeling sharing knowledge and experience to help fellow turf managers around the world improve and develop their skills.

Tips on Designing a Professional Baseball Field


   

Below  are a few general tips and considerations that can be used as a template or checklist when planning and or  building a baseball field.  First and foremost.

  • Hire your sports turfmanager, or field consultant.
    • Develop maintenance budget and begin to order equipment. A reputable field contractor can install a professional level field in 45 days so it’s important to be ready to take care of it when they lay down the grass.
  • Secure the services of a qualified surveyor and field contractor and or field project director. Making small mistakes during the planning period could result in costly maintenance problems down the road.
  • If you’re sodding the field, locate the grass source and determine the type you need based on your area.  It’s important to do this early in the process so you can have the turf tested and growing properly before it harvested.
  • Determine elevation and grade lines to confirm what existing grades are and how they will change to allow your field to drain properly.
  • Have a soil analysis completed to find out what type of soils your site consists of.  You will want to send the soil sample to a certified testing service that understands the difference between testing soils for roads, builds and sports fields. They are very different tests.  They will test for particle size, percolation, soluble salts and PH.
  • Roto-till hard pan and subsurface soil if your site proves to be an impermeable surface.
  • Install irrigation system mainlines and outlets.
  • Excavate and pour concrete footings for light towers, dugouts, stands and locker room.
  • Install the drain tile system, drain outlets, sewer system.
  • Install electric lines, cables, outlets to light towers, dugouts and stands
  • Lay out stabilized areas; haul in aggregate for warning tracks, paths to home plate in front of dugouts, coach’s box, on deck, and fungo circles.
  • Replace or prepare native topsoil – from soil analysis formula, mix in soil structure amendments. This material can be stockpiled on site.  Again if you are building a sand based field system you will remove all of the soil from the existing field and replace it with a pea gravel drainage system and sand based root zone for the growing medium.
  • Sterilize native soil materials if possible. Taking care of the weeds in this material can save a lot of money trying to spray out weeds in the future.
  • Roto-till the soil for uniform and thorough mixing. Rework the area to grade elevations with laser grader
  • Recheck grade elevations with surveyor’s report.
  • Roll the area to a firm soil.
  • Install backstops, fences, scoreboard, flag pole, foul line marker.
  • Build a pitcher’s mound
  • Spread a starter fertilizer before laying down your grass
  • Finish grading with laser device.
  • Remeasure diamond and recheck grade elevations carefully.
  • Set the home plate, pitchers plate, base anchors.
  • Mark all grass lines, circles, arcs and boxes with chalk or lime.
  • Plant the area (seed, vegetatively, or sod)
  • Build your bullpens and install warning track
  • Finish construction and installation of dugouts, light towers, stands, locker rooms, showers, toilets, storage space, concession stands, and parking lots

MLB Groundskeeper Hall Of Fame Trophy Named for Gary Vanden Berg


In a great show of respect for Gary a group of MLB Groundskeepers selected a couple of sport turf industry greats in the trophy’s inaugural year.  George Toma and Emil Bossard were announced as this years recipients for their outstanding contributions to the game and the sportsturf industry.   I never had the pleasure of meeting Emil but  have spent a little time with George over the years at conferences and turf events.  He is a true inspiration to the world of groundskeeping.  The Hall of fame committee members are Bill Deacon Mets, Trevor Vance and Justin Scott Royals, Bob Christofferson Mariners and Mark Razum Rockies.    

To be considered for induction in the MLB Groundskeeper Hall of Fame, a person must have made a significant contribution to the sportsturf industry at the major league level and has not been employed full-time in the profession for at least 5 years.

Gary was one of the kindest people in the sportsturf industry.  Always one to answer a question or talk about his field.  He will be missed by many. Naming this award in his honor was truly an easy selection as it passed unanimously by the association members.

MLB All Star Tour in Taiwan shifts to Taichung City


Taiwan is a small island with 16 baseball stadiums.  Some of the parks are Triple A level and could host major baseball events.  Couple that with baseball crazed fans and you have a wonderful fun-loving culture of baseball.   Today we headed south to play in Taichung after completing a rain shortened game the night before in Zingzuan Stadium, New Taipei City. Photo above are the guys from Zingzuan.  great group and a great job buy the youth baseball team. 

The All Stars are 2-0 and last night’s game in Taichung’s intercontinental field was a close one up to the final couple innings before the MLB guys scored a couple making it 5-3,

Checked out the Pig on a spit in the stands. Literally right behind in the mid level seats section. Open fire in the stands, the works.   A real ballpark pig pickin!

Many of you know that Taiwan is considered the land of the scooters.  There are millions on the road daily outnumbering cars 3 to 1.  Well it appears Mr. Morse from the Nationals was inspired and picked up a scooter helmet which he was sporting during BP.  These guys are really having fun.  It’s a good mix. 

Fields are holding up.  Infields are soft due to the lack of clay on the island which is requiring extra dragging and watering and rolling etc… but the guys are doing a great job.  Greg ( Jones) , Eric and Ryan.  Keep it up!

Texas Rangers Groundcrew Sport New Bling


Stopped by The Ballpark in Arlington this week to visit with Dennis Klein, head groundskeeper for the Rangers and coincidentally it was ring day for the Texas Rangers American League Champions.  Each full-time member of his crew also recieved a championship ring.  Hats off to Nolan Ryan and the Rangers for taking care of the ground crew.    As usual the field looked immaculate.

The Baseball Field


 

What makes a baseball field so beautiful is in the eyes of the beholder but how it becomes that lush field of  manicured grass is all about the sportsturf manager and his staff.  (For those old-timers groundskeepers are now called sports turf managers.)   Baseball fields haven’t changed drastically since the 1840s back when the sport was known as knickerbockers. The bases were measured at 90ft then and they remain that distance today. The mound however has changed quite a bit.  In the last 20 years,  field playing surfaces for all levels have improved tremendously, Standards have increased and the need for safety was stressed.  even with all of the new fancy equipment and field protection materials there is still one part of the field that remains a true art.  Managing the clays. The infield mound and homeplate.  To hard or to soft.  It’s all about moisture and how your field takes the water during certain times of the year.  Mother nature has a calendar but she will sometimes tweak it a bit and throw everyone a curve like the Yankees practicing in a snow fall a couple of days ago.    The turf managers in the north had a pretty rough winter and  those fields are green and ready.  I’ve blogged a bit about  lot of How to grow your fields etc… but each spring seeing our fields go green after harsh winters is really amazing.  The amount of hours and time spent on maintaining these fields is immense.

With the 2011 Baseball season officially underway we need to say thanks to  our Spring training site ground crews  for getting the guys ready for the season and the job our MLB and Minor League clubs are preparing to begin. Have a great season!

Building a Baseball Infield


infield watered.jpgTechnically, the term infield skin refers to segments of the baseball field that contain clay, specifically the areas around the bases and base paths. The keys to quality infield skin are good materials, proper moisture and consistent maintenance practices. With 70 percent of the game played on the infield, having a consistently firm, smooth playing surface is essential.

Infield construction

Infield mixes are made from various combination’s and percentages of sand, silt and clay. People consider the general standard for an OK infield to be 60 to 70 percent sand, 30 percent clay and 10 percent silt. Particle size also makes a big difference in these materials. Infields vary greatly by regional conditions, commercially available mixes and the preferences of the sports field manager and their facility and teams.

The nail drag scarifies the surface and digs deeper to further loosen the infield mix. With any drag, be careful not to drag too close to the turf edge.
Annual laser-grading is used to check the infield slope and correct any inconsistency.

The weight of the infield mix is in the clay and the silt and that’s what retains the moisture. You may be in an area with a lot of rain, and if you don’t have much maintenance help for tarping you’ll want to have a bit sandier infield mix. If you have a heavily used field or one for university or professional play, you’ll probably want a more stable infield with a heavier mix containing more clay and silt to withstand the wear and tear of multiple events. For some infield mixes with lesser percentages of silt and clay, a conditioning amendment of calcined or vitrified clay is worked into the top 1 to 2 inches of the mix to help bind the clay and stabilize the infield.

When constructing a new field or rebuilding an existing one, the general depth of the infield material for the baselines is approximately 5 inches. The depth, the type of material used and the subbase components are subject to budgetary constraints. There are fields with the infield mix placed directly on the subbase soil, some on a sand layer over the subbase soil, some directly on a pea gravel layer and some on geo cloth covering any of these subbases.

Opinions differ on whether a geo cloth layer will be detrimental to drainage. While drainage within the infield mix will vary according to the percentages of clay and silt, it is generally slow, so many prefer the geo layer for other advantages. It can keep pea gravel from migrating up into the infield mix and bordering grassed areas. Geo cloth on the pea gravel does keep the infield mix from sifting into the gravel, reducing the need for continual addition of the mix during the first few years of construction and helping stabilize the surface more quickly.

To counteract slow drainage within the infield mix, many fields are constructed with a slope to help move the surface water off the clay and into the grass. A slope of about .5 percent, extending from the edge of the pitcher’s mound out past the 95 arc should provide sufficient water movement for most fields. Some skinned baseball infields and some softball fields are constructed with a greater percentage of slope.

It’s critical to achieve consistency of slope across the entire surface. Use laser-grading equipment and a skilled operator. Otherwise, once all the material is in place, run string lines from the infield grass to the outfield grass across the infield and work your way across the field with shovels and rakes. Keep moving the string lines every 1 to 2 feet, and check and recheck for accuracy as you move.

Managing moisture

An in-ground irrigation system with a zone that only waters the infield clay is one way to deliver volumes of water quickly. When water patterns are diverted in windy conditions, hand-watering will be required to reach the places missed.

Quick-connect outlets behind the mound and behind home plate provide access to hook up a water hose. Some field managers place quick couplers at the infield corners behind first and third base in the grass. A 1-inch hose is preferred to deliver a larger volume of water faster. A retractable hose reel installed in the ground behind the mound makes pull out and rollback easier and eliminates hauling the hose out and back for each watering.

Select hoses and hand-nozzle sizes based on the number of fields you need to maintain and the size of your crew. Ideally, your nozzle selection should be able to apply enough water to reach the desired depth for the initial soaking and to lightly mist repeatedly to maintain the desired moisture level. Some infields drain so well that you can “puddle” the infield after a night game and it will be perfect for play by morning.

When necessary, crews can level the infield skin using a string line and hand-held tools and hand-pulled drags.

Top it off

Using the different calcined or vitrified clay amendments as the top surface coat can make it a little easier to manage the skin moisture levels and achieve consistency. You don’t want the players to pick up wet clay on their spikes or have the infield get too dry during the pregame workouts. With a topping of 1/8 to .25-inch, you can soak the infield as you would normally and have a good surface for workouts and sufficient moisture retention for the game. Consistency of depth is extremely important during the initial application of the top layer both for accuracy of the slope and footing for the players. Once in place, use a cocoa mat or the back of a fan rake so you’re just lightly smoothing the top surface and not moving piles of material.

Dry down

An infield tarp is an important tool in moisture management. No one likes to use it, but covering the infield when you have rain issues can be the quickest and easiest way to preserve playability.

Edging the infield as a weekly maintenance practice will reduce lips and keep turf edges smooth. This Turfco Edge-R-Rite was used in 2004 during the Olympics. Along with edging the bermudagrass, it doubled as a small sod cutter.
Rolling infields is an important practice to stabilize the areas.

The worst thing you can do following a heavy rain on an uncovered field is to work the field too early. Let the sun do its work on the dry down before you get out there to squeegee, rake and dig. The dryer subsurface material will try to draw down the moisture from an undisturbed wet surface. If you must work existing or added material to dry down the surface, use a roller squeegee rather than a rake to spread the water so you’re not cutting into the wet material and disrupting that downward movement.

If you have depressions with standing water, fill them with calcined clay and let it soak up the moisture for 15 to 20 minutes. Then, spread out that moist material to dry further, or borrow a technique from ground crews in South America to remove excess water with no surface penetration. They use a supply of 12-by-24-inch foam-rubber sponges (old padding) and place one in an area of standing water, step down on it, allow it to absorb water to capacity, pick it up, wring it out and use it again.

Another technique to combat light rain or drizzle, and to use between innings when the dirt is starting to look shiny, is to apply a very thin layer of conditioner using a regular walk-behind or hand-held spreader set for the largest opening. You’ll get a more consistent layer than pouring conditioner from the bag or putting out piles to spread.

Working the dirt

The right equipment used properly is critical in maintaining the infield skin. You’ll want a series of different types of drag mats, rigid and flexible steel mats for breaking up dirt clods and leveling, and cocoa mats for finishing the surface. You’ll need both a fine nail and heavy nail drag for scarifying the surface and digging deeper to further loosen the mix and allow better moisture penetration. You’ll need rakes, brooms, edgers and rollers. The 1 or 2-ton roller will become your favorite tool.

The three-wheel field rakes produced by the major equipment suppliers do an excellent job, and they come with an assortment of attachments, as well as connection points for other implements. You also can use a small tractor, lawn mower, utility vehicle or golf cart to pull the drags.

We bored into the infield to check soil conditions and discovered a layering of different clays. We had to rototill to remove the barriers so the clays would not “plate” when the players took the field.

Always pull the bases and insert the plugs so you can drag the entire infield. Pay close attention to the wear areas around and in front of the bases, such as where the first baseman plants his foot. Consider incorporating a heavier clay mix 10 feet out from first base and also at second and third base to make it easier to reduce divoting and keep indentations from forming. Follow different routes when driving equipment onto the field to reduce compaction issues. Transport the drags to the field and drop them at different spots each day. When working the field, keep attachments, drags and screens 6 inches away from the grass at both edges of the base path to avoid lip build up. Use a variety of dragging techniques, continually altering your patterns and incorporating circular spirals and figure eights. Go slow, especially in the turns, to avoid slinging materials.

Managing Lips

To avoid creating lips when hand-raking, always rake up and down the base path, not across it. Work the grass edges with a fan rake or stiff-bristled broom after every practice, workout and game. If you don’t have the staff for that, use the water hose to blast the infield mix from the grass edges at least once a week.

You’ll want to edge the infield grass periodically, cutting away turf to remove any lip buildup, then backfill with new infield mix, tamp down firmly and test the edge. There should be no transition between the grass and the clay. If you can feel even the slightest difference with your foot, the ball can feel it when it hits, and that’s what causes a bad hop.
