Understand that I’m not a pitching coach. I’ve never played one on TV, and if I were asked to serve as one for an actual team, I’d be wildly out of my element. Pitching is complicated, and pitchers in the major leagues are impossibly good, and pitchers in the major leagues also have reasons for doing what they do however they do it. I don’t know if what follows is good advice for Kevin Gausman and James Paxton, or garbage. It’s just, there’s at least enough here that we can have a conversation.
Thursday, I wrote about the Rays and collecting and encouraging high fastballs. I’m interested in this high-fastball thing — it’s an intuitively sensible way to attack hitters who are increasingly prepared to hit down low. The Rays have talked about this idea. The Astros have talked about this idea. Brandon McCarthy has talked about this idea, during an interview for the Hardball Times Annual. It’s a trend, seemingly, to counter a different trend. But it’s worth noting, not just any fastball should be thrown high. You need to have some command, and you need to be able to generate the right kind of spin. You want to have a fastball — a four-seamer — with a high PITCHf/x vertical-movement reading. That’s not the way pitchers themselves think about it, but that’s how we can understand it.
