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.
Yankee Stadium
On April 21, 2014, it was announced that New York City FC, a Major League Soccer expansion team owned jointly by the New York Yankees and Manchester City, would play in Yankee Stadium from 2015 until their new stadium site is determined and the stadium is built. NYCFC played their first game at Yankee Stadium on March 15, 2015. Because of the unique dimensions of the Yankee Stadium field, the playing surface of the soccer pitch is 110 yards (100 m) long by 70 yards (64 m) wide—the smallest field in all of Major League Soccer, and the smallest allowed by FIFA's international guidelines.
