The 2014 MLB all star series will be held the first couple weeks of November. The best of five series will be played in the Osaka, Sapporo and Tokyo domes with two exhibitions planned at Okinawa and Koshien. The history of the Japan All star tour event dates back quite a ways. This will be the 36th time a group of MLB players will travel to Japan to compete in a friendly series and the 11th All Star tour.
during the site checks our first stop was Okinawa. A small island located way south of the mainland. It’s about a 2 hour flight from Osaka. There is a lot of history in Okinawa as it was considered the turning point of WWII. This is a really cool ballpark which sports a Japanese traditional baseball field which is composed of an all dirt infield. Japanese players have been competing on these type of fields for over 75 years. It’s a 25000 seat park and it was very loud and clear that the Okinawans are excited about hosting an exhibition game. There is a large military base located near by and I’m sure there will be some serious fans supporting their favorite MLB and Japan All stars.
There are two parks proposed for competition in Osaka. Koshien stadium is the older venue with the most history of baseball in the country. Connie Mac brought a tour here in 1934 featuring the likes of Babe Ruth and others. In the early 90’s MLB international and the players union had another tour which stopped by koshien. The park is truly unique hosting the national high school tournament every year. The park is packed for these games. The venue has a all dirt infield, big foul territory and a natural grass outfield. Koshien stadium is about a 30 minutes drive from the Osaka dome.
The other venue planned for games is the Osaka dome. I remember last time it was for the 2004 MLB all-star series. It was good seeing old friends and more importantly seeing the mound and homeplate improvements they had made. They did an amazing job at matching the infield clay around the base pits with the synthetic turf color.
The 4th planned venue is in Sapporo and it is also a domed ballpark. Again this is another impressive dome with huge foul territory and a synthetic turf surface. The outfield wall is about 20ft tall and the distance to the fence is respectable at 330 down the lines and 400 to center. This venue has the ability to open the center field wall and “float” in a regulation size natural grass soccer pitch. The size of the building is massive. I was told by the local management that the entire Tokyo dome can fit inside this dome!
The Main venue for the games will be in Tokyo at the ever so popular and well-known “big-egg” . The big news for this venue is it has a new synthetic turf surface which was really needed. The amount of events this facility sees is truly impressive. Always great to see and work with our friends at Yomuri and the grounds staff in the Tokyo dome.
Looking forward to the tour and working with our Japanese friends.
Plans are well underway for the World Baseball Classic in all of the ballparks around the world. Its hard to believe that the event starts in about 3 weeks! As for the international venues, in the first round we have Hiram Bithorn in San Juan Puerto Rico, Fukuoka Dome- Japan , Intercontinental Stadium- Taichung Taiwan and Tokyo Dome in the 2nd round.
Hiram Bithorn Stadium – The old park built in 1962 is seeing some upgrades to the field, batting tunnels, padding, basically a little facelift. Hiram Bithorn has seen 2 previous rounds of the WBC action and the teams competing at this latin themed ballpark will create some real excitement for the fans! Dominican Republic, Puerto Rico, Venezuela and Spain. each club loaded with big leaguers. It will seat about 20,000 and is an open air synthetic turf field. Same dimensions of 325 down the lines and 400 to center.
Fukuoka Dome – Also known as Fukuoka Yahoo. We last played here during the 2006 All Star Tour. An all synthetic turf field with great site lines. Not a lot of improvements but they will see a few upgrades to the mounds and homeplate. It seats about 38,000 and was Japan’s first re-tractable roof stadium. With dimensions of 328 down the line and 400 to center its a big park with quick turf. The teams competing here are Japan, Cuba, China and Brazil. Intercontinental stadium – We just played the 2012 All-Star tour in this venue as well as several Baseball World Cups over the years. An all grass playing surface that is undergoing some improvements to the outfield and infield for the tournament. Our guys, Kevin Moses and Joe Skrabek are currently there assisting the local governments with the improvements. With distances of 325 down the lines and 400 to center field we witnessed some great baseball here for the 2012 All Star Tour. The fans in Taiwan are second to none when it comes to supporting baseball. Exhibition games are being played in Dio-Liu stadium which is about an hour outside of Taichung. Teams competing here include Korea, Taipei, Nederlands and Australia. Tokyo Dome – MLB’s season opener took place here in 2012. A very long history with MLB and Yomuri. A great partner in developing developing the game in Asia. They will see the basic improvements to the mound and home plate areas. A great ground crew headed up by Tamba and Hokike. Good luck to all the teams and federations. Its going to be a great tournament.
What a week. A lot of firsts even for this old dog. Great games both pretty close. A’s came out ahead tonight so now the A’s and Mariners are tied for 1st place for about a week. A lot of thanks go out to way to many people I cant remember for helping us pull this one off. Tamba, Hokike and my man Kas. Shawn took us through the first steps and chad Olsen played the key roll in making the event successful Along with the masked man and moma boss. Both supervisors that we nick named for fun
What a great crew of Japanese and American turf managers. Couple other fun shots of the final game.
Then there is cepesdes
And my fav..UMPIRES TRAINING!
Plans are well underway on the field and ballpark improvements at the Tokyo dome for the 2013 MLB Opening Series. Teams arrive tomorrow, practice saturday then back to back double headers before the opening games on weds and thursday between the A’s and Mariners . Reconstruction of bullpens, homeplates, mounds, base pits, turf repairs, etc… took place over a 38hour time frame due to the event constraints around the opening series…The guys worked in shifts from the crew but there were a few Yomuri warriors along with the grounds supervisors that worked straight through along with Chad-son an Murray-son. The dome is a slightly pressurized facility that helps support the roof membrane that covers the stadium. Built in 1988 on the old Velodrome site, you can still walk in the outfield and see the track railings. Every time you leave the park your ears pop from the pressure in the building.
This is our 5th time working in the “egg”. The staff has always been great and they recently made a few changes. The head groundskeeper Hoshimoto an his trusty assistant Suzuki retired last year after working 50+ years with yomuri giants and the Tokyo dome . They look like they are both 40! A true inspiration to sportsturf managers around the world. 50 years with one company! Hoshimoto was telling me about the earthquakes and how the dome was swaying last night. What’s cool is they promoted Tamba and Kohike from within showing consistency and loyalty to the young guys on the crew. The Dome is showing its age but at the sametime versatility to be able to host major events throughout the year similar to the rogers centre in toronto.
Going to be a fun event…i really like not having that big tarp to mess with!
Baseball’s mound has evolved over the years. Back in the late 1800s, it was 45 feet from home plate and the pitcher could take a couple of steps with the ball when throwing. Later, the pitcher had a 6-foot-square box as the designated area and had to stay within that box when throwing. The mound was initially defined in the rules in the early 1900s with the pitching rubber at a height of no more than 15 inches above home plate. Because mounds were at varying heights up to 15 inches, the rule was changed in the 1950s, setting 15 inches as the uniform height. Baseball became a pitcher’s game. In the late 1960s, pitcher Bob Gibson had an ERA of 1.12 and MLB’s top hitter, Carl Yastrzemski, was batting .301. During the 1968 season, over one-fifth of all MLB games were shutouts. The rule was officially changed in 1969, establishing the height of the pitching rubber at 10 inches above home plate–period–not 10 inches above the grass. That rule changed the way the game was played. At 15 inches, pitchers were told to “stand tall and fall.” With the change to 10 inches, it became “drop and drive.” The pitchers would drop down and push off from their right or left leg.
That 10-inch height is mandatory for major and minor league baseball, NCAA Baseball and most high school programs. (Check the official governing body for rules at each level of play.)
This is the method I use for new construction or total reconstruction of a mound. There are many other methods, but I’ve found this is the simplest way.
You’ll need a plate compactor, hand tamp, landscape rake, shovel, level board, hose and a water source. I prefer the professional block-type, four-way pitching rubber. You can flip it each year and get four years of use from it.
The most important thing you need is the clay. I suggest using two types: a harder clay on the plateau and landing area and your regular infield mix for the sides and back of the mound. The harder mix has more clay, with a typical mix about 40 percent sand, 40 to 50 percent clay and 10 to 20 percent silt. The infield mix for the rest of the mound is typically about 60 percent sand, 30 percent clay and 10 percent silt. Suppliers offer several options in bagged mound mixes, some of which come partially moist, some almost muddy and some as dry as desert sand. Be aware of those factors as you evaluate your clay sources. Any of the commercially bagged, vendor-provided mound mixes are heavy in clay and good to work with. When you purchase the material from a vendor, you know you’ll be getting the same thing each time. Bricks are also available for the harder clay. Some people prefer these, which are packaged moist and ready to go into the ground. Others prefer the bagged mixes for more flexibility in establishing moisture levels.
You’ll want to have 8 to 10 tons of clay available to build the mound; 2 tons of the harder clay and 6 to 8 tons of the infield mix. You’ll need wheelbarrows or utility vehicles for loading and unloading it–and people to help move it.
The most accurate way to set your distances and heights is to use a transit with a laser. If you don’t have access to this, you can use a string line run between steel spikes with a bubble level that you clip onto the string. Or, you can build a slope board.
Tackling the task
Plan for the proper orientation when constructing a new field or when building a mound for practice purposes. You’ll want the line from home plate through the pitcher’s mound to second base to run east-northeast so the batter isn’t looking into the sun when facing the pitcher. As you prepare to construct the mound, use the transit and laser or string lines to make sure home plate, the pitcher’s mound and second base are accurately aligned and everything is square.
For a regulation MLB field, the distance from the back of the home plate to the front of the pitching rubber is 60 feet 6 inches. The typical pitcher’s mound is an 18-foot circle with the center of the pitching mound 18 inches in front of the pitching rubber. That makes the measurement from the back of the home plate to the center of the pitcher’s mound 59 feet. Too often, the rubber is accidentally placed in the center of the pitcher’s mound so be sure you have the measurements right.
If you’re using the string line, place one steel spike behind the pitching rubber location and one just beyond home plate. Put a pin at the 59-foot point in the center of the mound area and stretch a 9-foot line out from it, moving it all around the pin to mark the outer line of the 18-foot circle. If the grass is already in place, protect it with geotextile and plywood while you’re building the mound.
Leave the pin in the center and place a second pin where the pitching rubber is going to be and mark the pin at 10 inches above home plate. Then, start bringing in the clay to form the base of the mound. Establishing the right moisture content within the clay mix is the key to building the mound. That consistency has been described as just a bit drier than that of Play-Doh when it first comes out of the can. It’s one of the instances where the science and art of sports field management mesh, learning by doing what that right consistency is given the material being used, the outside temperatures and humidity levels, sun, shade or cloud cover, wind speeds and direction. These factors vary daily–and often hourly–and make a difference in the formula that will keep the mix at just the right moisture level.
That’s why you will build the mound in 1-inch levels, creating the degree of moisture you want in each level so it will be just tacky enough for the new layer to adhere to the previous one. Use a tamp to compact each level. It’s important that the hard clay used to build the plateau and landing area is a minimum of 6 to 8 inches deep. You can put down plastic or wrap the tamp with a towel or piece of landscape fabric to keep it from sticking to the clay. You can’t add soil conditioner between these layers, as that will keep them from bonding together. Check the measurements of the height, using the transit and laser or the string line, with every lift of clay.
When you’ve built up the subbase with hard clay at the 60-foot-6-inch area to a 10-inch height, construct the plateau 5 feet wide by 34 inches deep. Position the front of the pitching rubber 60 feet 6 inches from the back of home plate. Set it firmly in place, making sure it is level across the length and width, with the top surface exactly 10 inches above the level of home plate. Draw a centerline through the pitching rubber and run a string from home plate to second base to confirm the rubber is centered.
With the pitching rubber in place and the plateau completed, you can begin to build the slope toward the front of the mound. Begin the slope 6 inches in front of the toe plate creating a fall of 1 inch per each foot. Double-check the accuracy of the slope using the transit and laser or the string line.
You’ll be using the harder mound clay to create the pie-shaped front slope of the mound, as this section will provide the landing area for the pitcher. Use the same method of clay mix, water and tamping, working in 1-inch increments.
You’ll use the infield mix to construct the remainder of the mound. Begin working from the back edge of the plateau using the same layering process. Use the edge of the slope board or a large wooden plank, positioning the top edge on the back of the plateau area and the other edge of the board on the edge of the grass to guide the degree of slope for the back and sides of the mound. Looking at the mound from the front as a clock face, you’ll be completing roughly the area from 9 a.m. to 3 p.m. to transition into the wedge in the front of the mound. You’ll want a smooth area of slope for the back and sides so that the side section precisely meets the edge of the pie-shaped wedge that is the front of the mound. Upon completion, the mound should look like a continuous circle with no indication that different materials have been used.
The dimensions, working from the outer edges of the 5-foot-by-34-inch plateau, are mathematically accurate to make the back and side segments a perfect fit. They tie into the wedge with the 1-inch to 1-foot fall of the front slope that begins 6 inches in front of the pitching rubber.
Once the mound is completed, top it with a 1/8-inch layer of infield conditioner so it won’t stick to the tamp. Then, cover the mound with a tarp and keep it covered to prevent it from drying out and cracking. Once the mound is properly constructed, you’ll have only the easier, but ongoing, task of managing the moisture level as you repair the mound after every practice and game.
