That wasn't possible based on when he started his rehab assignment. In fact, I think they waited as long as they possibly could before they brought him back. They could keep him on the DL, they just couldn't continue the rehab assignment. Another possibility has come to my mind, though. Perhaps Blanco or Baker will conveniently become "injured" and get placed on the DL, to be acivated when rosters expand in September. That would avoid the need to send anybody down.
