"We wanted to give it a day of rest," Astros manager Brad Mills said. "He's still going to go through some things on the other fields. He's not going to throw on the other fields. He'll do some bunting, but no hitting. As of right now, we're not concerned about it, because he didn't hurt it while throwing."
Also, left-hander Wandy Rodriguez, who experienced tightness in his lower back while throwing Thursday, is being closely monitored and is expected to take his scheduled turn on the mound Saturday. Rodriguez did all of his non-throwing drills Friday, but it was tempered.
"If we think it he's going to do something that has the tendency to tweak his back or something, then he's going to go at it a little bit easier," Mills said.
