"We're going to make sure everything is OK with his arm as we progress," Reds pitching coach Bryan Price said on Tuesday. "He's had just some little moments where he's had a little bit of tenderness. It hasn't necessarily been consistent with his shoulder injury. Since we're going to be in Cincinnati in a couple of days anyway, we figured we'd get a head start on it."
Team medical director Dr. Timothy Kremchek will look at Marshall. The news is disconcerting since the lefty setup man seemed to making solid progress during his throwing program.
"I'm concerned in that he's had some discomfort in his shoulder, on and off, since March 20," Price said. "We haven't been able to get him completely pain free. I think he's stronger now than he was early in Spring Training, but we haven't been able to get him to the point where we can take the next step, which is a rehab assignment. We've gotten close, but not over the final hurdle."
