Fact: one of the most exciting areas of study right now is catcher defense, and catcher pitch-framing. A little bit of the shine is off, but we’re still making discoveries, and the whole thing is exciting because at last we’re able to put some numbers to something that’s long been suspected or known. Previously, we were left with guesswork and anecdotal evidence. Now we have an understanding of who’s good and who’s not good, and though it’s all still evolving, more and more people are aware of it, and more and more people are talking about it.
Yet conversations about pitch-framing are seldom just about pitch-framing. Practically every time it comes up, the conversation turns to whether or not this ought to be left to skill. Sure, some catchers receive better than others, and it can make a meaningful difference. But why should it be that way? Why can’t umpires just call consistent strike zones for everybody? Why can’t we just have automated, perfect strike zones, to even the playing field? And so on and so forth. It’s exciting that we’ve identified pitch-framing as a talent, but people are split on whether or not they want this talent to keep having an effect.
