Thanks, Dave. I wouldn't have Arias or Cabrera on top-40 at this point, either. Having a high upside perception is one thing, but at some point there comes a time to retract the perception. If Arias is struggling as a low-A reliever, perhaps it's less that he's underachieving his perceived high ceiling, than that his ceiling perception just isn't accurate at all. In terms of reappraising my evaluation of a guy's tools and ceiling, personally I tend to pull the plug faster on hitters than pitchers. I think pitchers are more likely to improve. They get bigger/faster; they adjust their mechanics; they add a cutter, or develop an effective slider; they get more consistent with their stride and the reproducibility of their arm angle; they get better at hiding the ball and using the same motion for their pitches; they tinker for years before finally finding a grip that works. (Samardz comes to mind….) So I think it's not that uncommon for a pitcher who's got a really good arm and fastball command to grow into his ceiling. But I'm much less a believer that many hitters do that. If the speed and movement of pro pitching is too much for a hitter to really be able to process well, I don't think they very often just grow out of that. Absolutely they can grow into power. But I kind of feel like if a guy struggles hitting in the low minors, it's rare that he'll grow into being a good hitter in the high minors or majors. Certainly every hitter has slumps. Especially in April cold. So Martin may be a very fine hitter who had an 11-game April slump last year, and an 8-game April slump this year. But often if a guy isn't hitting in low-minors, no matter how toolsy his defense and arm and speed and BP power may look, if he doesn't hit in the low minors there's a pretty good chance he just doesn't really have the hitting talent to become a good big-leaguer.
