Doesn't alarm me either. I never pay attention to comps, each player is unique. Right now the only thing that has me worried about Perez is that he won't beat out as many infield singles as he rises in the ranks. Other than that, the guy is an extremely tough out at the plate, is a terror on the basepaths, and plays amazing defense. He is promising, but sure, each prospect has a good chance of failing somewhere along the line.
