It's hard to say what his ceiling is, cause no one really knows if his power will develope at all. He shows very good power (to hit possibly 20 HR's), but only in batting practice. The good news is he has great speed, a good bat, and is a very good SS. If I had to throw out some numbers I'd say around, .280, 10-15 HR's, & 20+ SB's ... the rest more or less depends where he bats. He really needs to work on walking more if he wants to be a table setter, as of right now he really lacks in that area though.
