Frustrated by a shoulder injury, Clay Buchholz will seek a second opinion from Dr. James Andrews on Monday in Florida.

The hope, John Farrell said, is that Buchholz will gain some "peace of mind" from his exam.

Buchholz has not pitched since June 8 and has thrown just 11 2/3 innings since May 22. He complained of soreness during a bullpen session Sunday in Oakland, bringing his throwing program to a halt.

"I think given all that Clay has dealt with, the start-and-stop throwing process, the rehab process associated with the shoulder, neck, all that, as we've said many times he's extremely frustrated with it," Farrell said.

"It seemed like he'd turned the corner with it on the trip to Seattle and the throwing he was doing, but it hasn't. To get some verification, clarification from Dr. Andrews to put his mind at ease is probably as important as anything he's dealing with from a physical standpoint."
