SLIDER? CUTTER?

BY WHATEVER NAME,

AN EFFECTIVE PITCH

Zack Wheeler’s slider is so good that it confuses even pitch-tracking systems. Wheeler maintains that many of his sliders, particularly to left-handed batters, are actually cutters. The pitches look similar and are differentiated only by subtleties in their horizontal movement.

Regardless, the evolution of Wheeler’s slider/cutter is a big reason for his ascension from the ranks of very-good pitchers to elite. Here’s a breakdown of his usage of the slider/cutter and its effectiveness over the years:
