Liriano’s Change

Moreover, I’m going to quibble with O’Leary’s assertion that the slider is a harder pitch on the elbow. Studies have shown that, thrown properly, the “cost” of a slider is not significantly higher than a fastball. (You can check for yourself at this link. I’m sure you’ll recognize a couple of the names involved, attesting to the quality of the study.) The big caveat is “thrown properly,” which allows any pitch to turn into a potential injury, not to mention anything of in-game or seasonal fatigue issues.
