ST. LOUIS -- Cesar Izturis inched closer to a return to active duty on Saturday, while Troy Glaus was cleared to play for at least the Cardinals' two upcoming afternoon games.

Izturis, who has been out since Tuesday after he was hit on the right arm by a pitch, did not start Saturday afternoon's game against the Astros. However, he could pinch-hit or play defense if the situation dictated it.

"I think he could play in an emergency today if we needed him," manager Tony La Russa said on Saturday morning. "[I would] try to keep him out of [pinch-hitting], but I think he could if we needed him to. I'd probably play him in the field first."

Glaus, meanwhile, has had no problems in day games. Night games at home, however, have brought him blurred vision resulting from watery eyes. He was removed from Friday night's game after two at-bats when he was unable to pick up the ball coming out of Shawn Chacon's hand.

"It's been damp -- not just cool, but damp too," La Russa said. "You've got to pay attention to it. I just wish he'd told me before he went up to bat the second time. He had told Barry [Weinberg, head athletic trainer] that his eyes were watery, and they put some drops in there. But it would have been nice to call time and say, 'Hey, I can't see.' He tried to gut it out."
