Footspeed and Forcing Errors: A Case Study
Defensive errors have been a part of baseball history forever, but we seldom ever talk about them now. We’ve come to better understand the importance of range, and so we look beyond errors for our defensive evaluations. A guy might make an extra error or two simply because he’s covering a lot more ground than a peer. There’s also the matter of errors being subjective, some being obvious calls and some being coin flips. As for hitters, errors are mistakes by the other team. When a hitter smacks a ball in play and the defense makes an error, we tend to think of the hitter as lucky, because that shouldn’t have happened. So hitters don’t get a lot of credit.
But errors do happen, and they’re factored into some wOBA formulas, and there’s a line of thinking that faster runners can force more defensive errors, giving them a mostly unseen advantage. There’s the idea, then, that there’s indirectly some skill involved, which might mean a few extra runs. I, personally, have seen Ichiro reach a bunch of times on misplays, which might’ve had to do with his speed. The more a defender has to hurry, the more prone he might be to screwing up, which could be a thing worth talking about. We’re about to focus on Norichika Aoki.
