No idea. I think he has been mentioned as playing in some of Steve Potter's pieces. I do wonder if they held some prospects back, though he is on the active roster. They just have 5 guys to handle the 3 infield positions (3B, 2B, SS). Simmons might be more of a pure 3B these days, but the other 2 spots were manned by Lee and Minyety (the least prospect but maybe the best current player of the bunch) yesterday.
That left Azuaje and Jamari Baylor on the bench. Hope they play today. Injuries and promotions will sort things out. I know at Jersey Shore it would be really nice for Luis Garcia to be in Reading in a couple of months. The initial 30-man rosters too probably get pared back at some point (unless milb does not care any more because the point is to develop prospects, not push a 24 or 25 man roster like they used to).
