Pitching prospect Cesar Carrillo might need season ending elbow surgery after being removed from Monday's game with Triple-A Portland.

Carrillo was sidelined for all but 10 starts last season due to similar elbow soreness. If he undergoes Tommy John surgery he will be out for around nine months.

This is sad because both had/have bright futures ahead of them but will join the ranks of Mark Rogers, Humberto Sanchez, etc. most likely. If they both can recover, I still expect good things.
