It helps to have larger hands to throw this pitch. Because the fingers are spread wider than normal on the baseball, this pitch produces more stress from the hand up through the arm. While the mechanics are the same as a normal fastball, the stress it places on the hand and arm is different. Over time it is possible to damage the arm. It is therefore not recommended for younger pitchers to learn this pitch. Older pitchers should feel comfortable deploying this pitch, but to use it in moderation. The splitter is an effective pitch because the hitter generally picks up the movement later and either swings over the ball or produces a weakly hit ground ball.
