Pitchers in fast-pitch softball usually throw the ball using a windmill type of movement. In this style of pitching, the pitcher begins with his arm at the hip. A common way to be taught how to pitch is using the motions, 'repel', 'rock', 'kick', 'drag', 'toss'.he 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. The pitching style of fastpitch is different from that of slowpitch softball.
