If Buxton does go IL...which he probably will, by all means bring Martin back up, but Castro should get the CF duty, with Martin backing him up. The scary thing about Buxton this time, is that it's the same knee...and he didn't hurt it running into a wall, diving for a ball, or sliding. Not good. Maybe it's just some scar tissue discomfort and he's back soon. Gotta hope for the best.
