The motion of a split-finger pitch is similar to the outlawed spitball and at one time the pitch was known as the "dry spitter". When thrown, the pitcher must emphasize the downward pull of the pitch at the end of his motion. Thrusting the hand and forearm downward is what causes the reduced backspin relative to a fastball, and thus the appearance of "drop off the table" movement from the pitch. The split-finger fastball is a very effective pitch with runners on base. A common tactic is using the split-finger to cause the batter to hit into a double play. When thrown correctly, the split-finger's apparent last second drop causes many batters to hit the top half of the baseball therefore inducing a ground ball.
