What is the best thing about the baseball pitch called the slider?

Answer 1

To the batter the slider properly thrown has the batter thinking he is facing a fastball. This among other things fools the batter and he is not expecting the ball to waver in its flight to home plate. I filled in part of the discussion area to explore this pitch in more depth.

Answer 2

The slider is a good pitch to have as the batter sees the ball as a fastball but at the last moment the slider drops in front of home plate. Most batters can spot a curve ball by its spin or the pitching motion of the pitcher. The slider looks exactly like a fastball due to its speed and spin. A slider is thrown by grasping the ball with the index finger and middle finger not in the center of the ball, but off a bit to the right.
