Like I stated, 4 for 19. His BABIP is .400. His line drive rate is high, so I will give him that (even those numbers are above your typical line drive numbers). Yet only 3 walks so far. In all honesty, I see him as a .300 to .320 at best OBP guy with some years under .300. He also is not going to slug .655. Let's face facts, he is most likely a .450 type guy at best. So I see a .770 ceiling for him and will probably be a low to mid .700 guy. Which for a shortstop in today's league, especially one with a good glove, is not too bad. I see him probably being an above average SS. Yet that is as far as I would go, and I can even see him completely flame out if he is not good at making adjustments.
Of course I could be wrong and maybe he is the next Nomar Garciaparra (a SS who ended up hitting much better in the pros during his prime). Yet even Nomar was a .800+ OPS guy in the minors with stints where he was well above that.
I do agree, he is not a slap hitter. Yet he is certainly not a power hitter either. If he ends up being a .800+ OPS guy with a OBP above average I will be rather surprised, and not even this hot start has changed my opinion on that.
