Cust OK after blurry vision

Second baseman Ellis day-to-day with sore shoulder

SEATTLE -- Friday night's game against the Mariners wasn't an ordinary experience for Athletics outfielder Jack Cust.

Thanks to blurriness in his right eye that was present before the game started, he was forced to leave after just two innings and one at-bat. As he pointed out, seeing tends to be a pretty important part of hitting a baseball.

"It's never fun coming out of the lineup. I want to play, but when it's your eyes, it's too much," he said.

Cust, who hasn't had such problems before, had the eye checked out by a doctor after he came out and was supposed to see an eye doctor Saturday morning if he woke up and the problem was still there.

But he said it was better when he woke up, and although he wasn't in the lineup Saturday, the eye was not the reason.

"Jack's OK. I just elected to play [Rajai Davis] today against the left-hander," manager Bob Geren said. "[Davis] had a great game last night. Jack will take BP, he'll be available to pinch-hit."

Cust said he'll probably go have it checked out when the team gets back to Oakland.

Second baseman Mark Ellis had his own problems on Friday when he exited the game after just one inning of play because of pain in his right shoulder. Ellis incurred the injury when he slid into second base during Thursday's series opener and collided with a Seattle fielder while trying to break up the double play.

He said after the game that he had done well on strength tests administered by a doctor. Ellis tore his right labrum during a collision with shortstop Bobby Crosby in Spring Training in 2004 and missed the entire season. Ellis also missed a little time in late July this year when the shoulder became sore.

"He is still listed as day-to-day. He feels a little better today," Geren said. "He's not going to do anything today baseball activity-wise. He'll get treatment, and my guess would be day-to-day but probably two days at minimum."
