Little League Baseball field dimensions were originally designed with Little League teams in mind, not professional teams. But professional baseball teams are now building their own professional baseball field with a different set of measurements than those used by Little League teams. Many professional baseball teams play at a 90-degree foul line, which is one inch less than that on most Little League baseball fields. The inside dimensions are also different: It is now common for a baseball diamond to be constructed with a two-acre playing surface. The backstop is no longer a standard measurement, but was once a tradition adopted by many major league baseball teams. For instance, the New York Yankees plays at home in the Polo Grounds in New York City, which has a backstop of three acres.
However, professional baseball field dimensions are not the only thing that differs from Little League dimensions. Indoor batting cages and batting tee boxes are generally smaller than those found in Little League parks. Back then, players could not stand on short stumps, which means they had to leap relatively high into the box to hit. Now, the shorter the distance between home plate and first base, the longer the player has to jump to reach the plate.
In addition to the differences in baseball field dimensions, there are also some other features that differentiate the leagues. There are several age-appropriate sizes for pitching rubber, and most Little League baseball clubs have green bases with white edges; for other leagues, the edges are black. There are also few standardized rules in other leagues, so some leagues use different rules for different games, such as when it comes to the throwing of the ball and the running of the foul lines. But most important of all, each league has a designated player who plays every game on each team, which means every player must start at first base, regardless of his position on the field.
