Tennis polo
The sport is played on a grass field between 80 and 100 yards long and 50 to 65 yards wide. The goal area is a semicircular line with an 11-yard radius and the penalty mark at 13 yards from the goal. An experimental rule has a second semicircular line on the field with a 17-yard radius. Generally, a field for gridiron football or soccer can be used.
Ohio Stadium
Major League Soccer games were held at Ohio Stadium between 1996 and 1998. The home opener was held on April 13, 1996, against D.C. United before 25,266 fans. Brian McBride scored 2 goals and had an assist in a 4–0 rout. The field at Ohio Stadium was the smallest in the MLS, measuring only 62 yards wide by 106 yards long, limited by the track surrounding it. Because of the smaller market for soccer than Ohio State football, B Deck, C Deck, and the South end zone seats were closed, leading to a capacity of 25,243.
