I agree that it is silly to read too much into changes in release point and movement over small samples, but velocity stabilizes very quickly. I think it is one of the things that can give us useful information early in the season. I think the main problem last year was that MLB changed the process by which they captured velocity. So it made it impossible to measure it against previous years’ data, which is the only way you can even learn anything about velocity. So any analysis last year was fucked out of the gate. And it led to a lot of guess work and confusion. But even still, looking at the guys who had lost a lot of velocity a couple of starts in... things didn’t work out very well for that group. A lot of guys were either pitching injured or ended up injured. Some others proved completely ineffective and aren’t even in the league anymore. Even looking at our pitchers: Lackey was horrible and retired. Arrieta, Lester, and Hendricks weren’t quite as effective and all missed some time. Hendricks was the only one that saw his velocity recover. Most importantly though is that velocity changes have been shown to correlate with success. Obviously a change in velocity won’t affect all guys the same. But velocity matters. With release point, it’s guesswork if it’s just noisy, why it’s changed, what a change will result in, and why it will matter, if at all. A guy could just be pitching differently but with the same results. A guy pitching slower seems a lot different to me, though. So I agree that release point and movement is too noisy and doesn’t interest me much in small samples. But velocity changes still scare the horsefeathers out of me.
