X-rays on Scott Sizemore's left hand were negative, splendid news for the second baseman who was in no mood for a here-we-go-again tale. "Tell me about it," he said. Sizemore, who was hit on the back of his hand by a pitch Sunday, missed all of last season after tearing the anterior cruciate ligament in his left knee on the first day of spring training. Before his rookie season in Detroit (2009), he had ankle surgery. "I definitely don't need any broken bones or serious injuries at this point," said Sizemore, who's expected to be shelved at least until Thursday (the A's are off Wednesday) as the swelling subsides. "This is obviously good news." Sizemore was plunked by Colorado's Tyler Chatwood in the third inning. Sizemore played defense in the bottom half, then exited. Balfour's comeback: After throwing nearly 40 pitches in his latest bullpen session, closer Grant Balfour said he still could make as many as six exhibition appearances, beginning in a couple of weeks. Balfour, who underwent arthroscopic knee surgery Feb. 14 for a torn meniscus, said he remains in the "early stages" of recovery but added, "I'm not even thinking about the knee, but about getting my arm in shape." He was waiting to receive a doctor's clearance to further push himself. He'll next throw off a mound Wednesday.
