Somehow it’s still spring training, and it won’t stop being spring training for another week and a half. We’re at the point now where everyone is beyond ready for meaningful games to begin, but just because spring training might last too long doesn’t mean it doesn’t serve a useful purpose. In spring training, pitchers and hitters can start building up their stamina. In spring training, young players can try to push veterans for jobs. In spring training, teams make money! And in spring training, players can work on tweaks during live game action without the games yet being of any real significance. Players seem to be constantly making little adjustments.
Now, the people over at Hardball Talk do great work in chronicling all the best-shape-of-his-life stories that emerge around this time of year. It’s intended in fun, but it could also conceivably be of some analytical value. Here, I want to chronicle stories of pitchers making mechanical adjustments, tweaks to their deliveries. Implementing changes they made over the offseason, or even earlier in spring. I think it would be handy to have this information in one place, even if it’s presently unclear why that might be. It could be of use down the road.
I’ve spent a lot of time on Google, and below, you’ll find what I’ve recovered. Note that changes to delivery are not the same thing as trying a new pitch — that might make for an interesting but separate reference post. Also, this is about pitchers tweaking their mechanics, not hitters tweaking their mechanics. And finally, before we proceed, please let me know in the comments if there are stories that I’ve missed. I’m almost certain that there are, and there are possibly several of them. Think of this as crowdsourcing in a way, and if you provide a link, I’ll add the information to the post. Now, the rest of the post.
