Remind me. He's the older OK State guy, who had surgery? Kind of a college Maples, with a strong/fast arm and a lot of K's, but kind of a walk-an-inning guy? I'm sure I'm oversimplifying, but in my head I'm recalling him kind of as a 2K/1BB-per-inning type of wildman profile, right? Kind of an interesting wildcard, I'd think. As a relief guy who was a freshman, then coming back as a rehab guy, and then Covid-shortened, he'll turn 24 early summer, but only pitched 72 college innings combined. So probably with so little actual game pitching, and much of that in kind of rehab post-op mode, it's not entirely clear that what he's been past represents what he might be future. I'm fired up about the pitch-lab stuff and the optimism that they can develop pitch shape etc. But I admit I'm really curious and a little less confident about how much pitch-lab development will be able to help the wildman. Adjusting grips and delivery for better velocity and better pitch shape, that make sense. But does the pitch-lab have capacity to help wildman gain control? If so, how would that work? Heh heh, in chemistry research, we do proof-of-principle experiments, and if a new procedure works well for a case-study, scope-and-limitation studies follow. I'm kinda thinking that *if* there is proof-of-principle that pitch-lab-can help command, a guy like Leeper might be on the extreme-challenge end of the scope-and-limitation continuum for control-repair. You're totally right on the backstory. He's had an extensive history of wildness. It's improved a bit in relief, but he's still about 1 BB/inning. If you wanted a "proof of concept" to developing a pitcher with a wildness problem, maybe Riley Thompson? He sported a 6.8 BB/inning in his last season in college. Since with the Cubs, he's halved that. Not exactly a 1 to 1 situation, but perhaps there's a minor grip change, mental cue, or biokinetic fix for Leeper. Any of those could have happened in instructs. Will be interesting to dive into more.
