Oakland designated hitter Frank Thomas was cleared for game action Saturday following an examination on his left ankle by the team doctor. It was as simple as watching him run on dirt with spikes. "It's the first time he used spikes," Dr. Jerrald Goldman said. "Either it works or it doesn't work. We needed to talk to him and make sure the trainers said he ran well and without any problems. As far as I know he'll play (Sunday)."
