The Very Simple Explanation for the Better Michael Pineda
As I check the latest version of the leaderboard, I see that Michael Pineda currently leads all pitchers in WAR. Granted, it’s by only a little. Granted, a chunk of that just happened Sunday. And granted, WAR is a rough tool, especially for pitchers. Lots of stuff going on there. But something we know for sure: higher-WAR pitchers are better than lower-WAR pitchers. The guys at the top of the leaderboard are better than the guys at the bottom. And Pineda’s got an extraordinary strikeout-and-walk differential. Not only is it really good; in terms of K% – BB%, Pineda has gotten better by 10 percentage points, relative to last season. Only Danny Salazar is showing a bigger step forward so far in the American League.
Whenever you see a bump in performance like that, you have to wonder what changed. The first place a lot of people look is repertoire. And looking at the repertoire has a few steps — people look for new pitches, or new movement on old pitches, or new pitch mixes, or changing velocities. Sometimes people also look for changed release points. So goes the search for improvement explanations. As for Michael Pineda? He’s not throwing anything new. He hasn’t changed his movements or his arm slot, and his pitch mix is fairly similar. His pitches aren’t going faster. The explanation here seems to be one of the most difficult to prove, but also the simplest to convey. Pineda, from the looks of things, just has better command.
