Oakland Athletics pitcher Rich Harden will likely miss more than the 15-day minimum after a recent MRI revealed his strained oblique muscle was worse than originally thought. "We just know it's not going to be 15 days," Davis said Tuesday. "Hudson was six to eight weeks, so this is going to be between 15 days and six weeks. We'll just see how he progresses." Harden was disappointed to learn that he is probably going to miss at least three starts, including today's game, because he doesn't feel that bad. Of course, he hasn't tried to throw yet. "I'll feel it sometimes when I'm reaching for something or getting out of bed, but just walking around I feel pretty good," he said. "That's the frustrating part."
