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.
Frontier Field
The first professional club soccer game to be played at Frontier Field was a National Women's Soccer League fixture between the Western New York Flash and Seattle Reign FC on July 9, 2016, which had been moved from Capelli Sport Stadium. The selection of Frontier Field, and the decision to use an undersized, field (under the minimum width set by the league), was heavily criticized by soccer players and coaches.
