Jeremy Guthrie said his shoulder "gets better each day," and he remains hopeful that he'll rejoin the rotation Tuesday in San Diego. "It gets better each day," Guthrie said. "The little bit of soreness continues to improve. I haven't talked to anybody that makes those decisions, but if it's (about) how I feel, I'll be pitching." A decision will likely be made over the weekend, when Guthrie is expected to throw his first bullpen session since the injury. Thus far, he's only played catch from 200 feet.
