Here's the link to Hunter's minor-league stats:http://www.baseball-reference....id=hunter001ced
He seems to have some speed, based on his triples numbers, but doesn't steal a lot of bases. Not much power and doesn't walk a whole lot (48 is his career high). What he does, give Memphis an extra outfielder (they appear to be a little short right now with Hamilton and Luna on the DL) but he doesn't strike me as anything special, despite his "top prospect" rating with the Padres (that may speak more about the Padres, though). I imagine he's probably better defensively than Cazana, who I suppose can DH now.
Interesting trivia: he made his major-league debut on Opening Day last season against the Cards and scored what proved to be the winning run in the 11th inning when he pinch-ran for Cameron Maybin. The next day he pinch-hit and walked. He got a pinch-hit single two days later against the Giants, then went 0-for-3 over the next few games and was sent down to Tucson.
