2) Is there a "mechanical" reason for that? As a player gets taller, his range decreases or he can't get down on balls as easily? Or just a rule of thumb? It would seem that if YR is an excellent defensive SS right now, adding a couple inches might decrease his SS ability a little, but still end up better than Yunieski... (ok, maybe that wasn't the best example, but...) 3) Since you have seen MM's swing, I'm wondering if there have been some adjustments since he reached AA? He could barely crack .600 OPS at Brevard and below. But then in 2010, he hit around .725 combined in AA and AAA and .809 last year in AA and AAA. I can't imagine his swing in 2010-11 is the same as prior. He is doing something better. I've got to think his chances at being the next Mike Matheny are decent.
