The Split-finger fastball, also known as the Splitter is a pitch that became prevalent at the end of the 20th Century. The Splitter behaves like a Straight fastball on its way to the plate, making it looks deceptively similar to a Fastball but breaks down near the plate which can effectively induce swing and misses.

The Splitter is especially effective when used in combination with a good Fastball. Being able to locate the Fastball inside the Strike Zone's corners will force batters to chase the Splitter that comes after the Fastball as it is very difficult for the batter to differentiate between the 2 due to its somewhat comparable velocity of a Fastball.

Grip

The Splitter is gripped very similarly to the Forkball but not as tight or deep between the fingers. The grip allows the pitcher to both inject a good amount of speed on the pitch, unlike the Forkball, and also impart downward spin on the ball, causing the ball to break down at the plate.
