Gregorius is very rangy at shortstop. Good arm. It was just last year that Baseball America said he was one of the few people who were nearly as athletic as Billy Hamilton in our system. While he isn't quite on that same page, he is indeed one of the better athletes we have. I think he could develop some solid pop for a shortstop in the future when he gets more comfortable staying back on the ball (he is more of a slap hitter than I would like given what I have seen when he waits for his pitch and stays back on the ball). Defensively, he has the tools to be an above average defender at shortstop.
