What it is

Forward Extension is the distance the ball travels forward from the set point (where the pitcher pauses before beginning their delivery whether pitching from the stretch or the wind up) to the point of release. Forward Extension is measured in feet. Moving your set point may change your Forward Extension. pitchLogic identifies the point of release at the exact moment the ball loses contact with the pitcher’s fingertips.

Why it matters

A more consistent delivery and release point aids a pitcher in having more consistent performance. Having a consistent Forward Extension and release point makes it more difficult for the batter to identify the pitch type. Your Forward Extension is indicative of your stride length and leg drive, which directly impact speed.

How it is used

As a rule of thumb, Forward Extension is typically close to the pitcher’s height. If Forward Extension is significantly over or under the pitcher’s height, they may be over or under extending. This can cause losses in velocity, changes in Arm Slot, and other problems with mechanics. However, some variation is normal with different pitching styles. Since Forward Extension and stride length have a large impact on velocity you can fine tune your Forward Extension to improve velocity. Once you have identified your ideal Forward Extension, try to keep it consistent across all your pitch types.

Please note: If you don’t come to a complete stop at your set point, pitchLogic may not be able to capture your Forward Extension. When this occurs Forward Extension will be displayed as “-.-“. The accuracy of Speed may be reduced as well.
