Softball is a sport that is almost identical to baseball but women play softball and men play baseball. Softball originated in the United States during the 20th century. It was called indoor baseball and was played during the winter to keep in shape. Ever since 1933 this sport has been called softball. The rules of softball are very similar to those of baseball. The area above home plate between a batter’s knees and her armpits is the strike zone. After a batter hits the ball, they must advance to 1st base. The defence can get them out by throwing the fielded ball to 1st base before the runner reaches the base. Additionally, other base runners must advance if they are forced by a base runner behind them. If a player is on deck they are up to bat next. Interference is usually called when a player gets in the way of an opposing player to stop them from making a play. The mercy rule brings a softball game to an early end when one team has a very large lead over the other team. Battery is often called the pitcher and catcher. The first year of Olympic softball was in 1996 in the Atlanta, Georgia. The United States won the very first Olympics for softball. The length of a softball game is seven innings unless the score is tied thru seven. The distance between bases on a softball field is 60 feet. The distance from home to the pitchers mound is 35 feet to 53 feet. From home to the fence the distance ranges from 150 feet to 250 feet depending on age. With runners on first and second or if the bases are loaded with less than two outs and the batter hits a fly ball that can be caught by an infielder with ordinary effort, the batter is out. This rule is called the infield fly rule and prevents easy double plays. Softball is a great way for women to participate in a sport like baseball.
