"I feel good," Salas said Monday. "There's no pain. I have confidence and control."
Manager Mike Matheny would not estimate how many appearances the Cardinals would like Salas to get before he would return to the Cardinals' bullpen.
Though Salas made tangible progress in his rehab program while the Cardinals were on the road, Chris Carpenter's program remains somewhat stalled. The veteran right-hander threw a long bullpen session Sunday but is now dealing with some back tightness, Matheny said.
Carpenter, through a spokesperson, declined a request from the media to provide more details about the issue Monday.
