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.

The shortest fair fences in Major League Baseball are both in Boston's Fenway Park; the shortest fence that is nearly perpendicular to the foul line is the Green Monster. The left foul pole, renamed "Fisk's Pole" in honor of Carlton Fisk's famous home run in the 1975 World Series, stands 310 feet away from home plate. The right field foul pole, known as Pesky's Pole, is 302 feet down the right field line, although the wall there is nearly parallel to the foul line as it curves back to the distant right field wall at 380 feet. From 1958 through 1961, the Los Angeles Dodgers played home games in Los Angeles Memorial Coliseum, a stadium built for track and field; without the ability to move any of the permanent stadium structure, the Dodgers configured the field to result in a 251-foot left field foul line distance.
