X-rays negative on Sizemore's bruised hand

PHOENIX -- It's a break for Scott Sizemore -- and not to a bone for once.

The A's infielder, sidelined by one too many injuries in recent years, was relieved Monday morning upon learning that X-rays taken on his bruised left hand came back negative.

"That's definitely a good sign," said Sizemore, hit by a pitch during Sunday's game against the Rockies. "Even the tests they did yesterday helped me believe it wasn't anything too serious. They told me I wouldn't have been able to have had any kind of grip strength if it was broken, or I would've had shooting pain up my arm. Since I didn't have any of that, it was just precautionary to have an X-ray, and really, for peace of mind that all is well."

Sizemore doesn't think he'll be able to do any swinging for a couple of days, though a lineup card posted in the A's clubhouse for one of Tuesday's split-squad games would suggest otherwise. Sizemore is listed as the designated hitter for the club's road contest against Kansas City.

"We'll see how it feels," Sizemore said. "I'm obviously not ruling it out, but as far as I can tell, I wouldn't be able to swing a bat at game speed. We'll see what happens."

Manager Bob Melvin said he would keep the possibility open, rather than prematurely scratch his name off the list.

Sizemore was going to try to play catch Monday morning, "but if it hurts, then I'll leave it at that so this doesn't linger any more than it has to," he said.

"It still feels pretty similar to yesterday," Sizemore said. "I can tell any type of pressure on it creates a lot of discomfort. That's why I think a couple of days of treatment will be good for it."
