Really? Under 100 ABs of domination elevates him to that level? I do love how he has responded to the prospect hype, but every player goes through highs and lows throughout a full season. he hit really well all of last year, including a very strong showing as the second-youngest player in the arizona fall league. he has to still be one of the youngest hitters in the southern league and continues to rake. the three editors of the BA prospect handbook ranked him at 13, 16 and 29th best prospect in baseball, and obviously he's not moving down anyone's list at this stage. by midseason i'd expect some of the guys ahead of him to not be rookies any more (heyward, matusz, escobar, neftali feliz, maybe guys like strasburg, carlos santana, pedro alvarez) so assuming he continues to play very well, he'd almost certainly have to be considered a top 10 prospect. I guess we will see how he performs in the long haul. He can hold his own with the bat for a SS. Can he play D? Hopefully he isn't Ronny Cedeno with the glove - lots of promise and no consistency. I won't read too* much into his error totals as some of those fields look like the surface of the moon. Graduating to the Top 10 via absence of elite prospects speaks more to the nitpicking of what defines a "prospect" vs comparing Castro to his peers (service time)- to which we will ultimately be evaluating his performance.. * edit spelling
