The field remains natural grass. Naturally, Yankee Stadium has been the scene of many of baseball's greatest moments. Babe Ruth belted his 60th home run here in 1927, and Roger Maris broke Ruth's single-season record with his 61st in 1961. It has hosted far more World Series than any other park. Despite the presence of sluggers like Ruth, Gehrig, Mantle, and Jackson, no Major League batter has ever hit a fair ball completely out of the stadium, although legend says Negro Leaguer Josh Gibson pulled a home run over the left-field roof in 1934.
Foul poles are outside the playing field.
Any batted ball hitting a foul pole above the fence line is a home run. Bat racks are within the dugout. Any thrown ball hitting dugout railing or foundation and rebounding on field is in play. Any ball going into dugout or hitting other parts of dugout is out of play. The distance between the left-center field fence and the front wall of both bullpens is 30 feet.
