Fastpitch softball

Fast-pitch softball (also known as fast pitch or fastpitch without the hyphen or "fastball") is a form of softball played commonly by women and men, though coed fast-pitch leagues also exist. The International Softball Federation (ISF) is the international governing body of softball. The ISF recognizes three pitching styles: fast pitch, "modified" fast pitch, and slow pitch. Fast pitch is considered the most competitive form of softball. It is the form of softball that was played at the Olympic Games in 1996, 2000, 2004, and 2008. The fast pitch style is also used in college softball and international competition.

Pitchers throw the ball with an underhand motion at speeds up to 75 miles per hour (121 km/h) for women and up to 85 miles per hour (137 km/h) for men.
