Interesting blog post on Yahoo:
The skinny, he's only in high A ball, but he looks like he may be the most terrifyingly fast players we've seen in some time. Last season: 103 sbs in 133 attempts (for a solid 77% rate) over just 135 games. They HAVE to know he's going to go, and he's still swiping them. He's swiped 31 bases in 38 tries (84%) this season, in just 26 games.
He's also Baseball America's #48 prospect. But he's far from perfect (and probably not Rickey). He's still low in the system, but he does strike out a bunch, and his defense has not been very good (39 errors, .932 fielding % last year, 8 errors, .922 fielding % this year).
Is he the next Rickey? Probably not. But an amazingly fast player who will sell tickets and terrorize opposing catchers? Possibly.
