Spencer Medick Addresses Splitter Spin

Not all splitters are the same. Hybrids are common — think “splinkers” and split-changes — hence the variations seen in both velocity and movement. The human element is also at play. Regardless of the grip, one pitcher’s split isn’t necessarily going to behave exactly like another pitcher’s.

Fifteen of the 71 pitchers who have thrown a splitter this year (minimum 10 innings pitched) are averaging fewer than 1,000 rpm, with Smith being one of seven under 800 rpm, the others being Logan Gilbert (687), Hunter Barco (689), Mark Leiter Jr. (689), Fernando Cruz (774), and Roki Sasaki (776).

Previously with Driveline and Prime Sports Performance, Spencer Medick is now the pitching coach for the Scranton/Wilkes-Barre RoughRiders, the Triple-A affiliate of the New York Yankees.
