Carlos Santana isn't expected to return to the Indians' lineup until the final game of this series as he continues to rest his stiff back and ailing bat.

"We're shooting for Sunday," said manager Manny Acta. "Carlos is feeling a lot better. He tested very well with [head trainer] Lonnie Soloff."

Acta said Santana will most likely DH Sunday with the Orioles starting left-hander Brian Matusz.

On Friday Santana said he was still feeling some tightness in his back and right side, but added, "I'm much more comfortable than I was. I'll try to swing and throw Saturday."

Soloff didn't say if Santana was suffering from a strained oblique muscle, which usually means a trip to the disabled list. He said Santana was suffering from soreness in his lower back and sides.

"He's a switch hitter and he's been swinging and missing a lot," said Soloff. "That can take a lot out of you when you're geared up for a fastball and they throw you an off-speed pitch."
