A.J. Burnett had a cortisone shot Monday to dull the pain in his groin. He will require surgery at some point to correct a small inguinal hernia. 

"Surgery at some time" is a bad omen for future performance. I would keep him rostered but would have a back up plan in place, just to be safe.ANALYST: Ivar G. Anderson Burnett has obviously been effected by the injury, at lest in terms of his control as he has walked more batters than he has struck out (14 BB:10 K in 16 IP) making him a risky own going forward even though he has a respectable ERA of 3.94 through his first three starts.
