Gerrit Cole, Dallas Keuchel, and Charlie Morton on Developing Their Fastballs
Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.
In this installment of the series, we’ll hear from three pitchers — Gerrit Cole, Dallas Keuchel, and Charlie Morton — on how they learned and/or developed their go-to fastballs.

Gerrit Cole, Astros
“It’s all about the fastball. From a young age, I’ve thrown both the two-seam and the four-seam. I just try to keep my fingers on top of the ball and get after it, man. It’s pretty simple.
“You try to locate it the best you can, knowing that overcooking the pitch — whether that’s overthrowing it or overthinking it — can cause you to maybe leak the ball over the plate or simply lose some of the quality of the pitch. You try to be as relaxed as you can, and have the most-connected delivery that you can. You keep your fingers on top of the ball, spin it, and take it right through the glove. Don’t try to do too much. Just let it eat.
