Webb may need season-ending surgery

D-backs ace seeking second opinion before deciding

PHOENIX -- Brandon Webb has a big decision to make.

Webb had an MRI exam on his right shoulder Tuesday and was evaluated by team doctor Michael Lee to determine the next course of action and treatment. Webb previously treated the ailing shoulder with rest and strengthening exercises.

Season-ending surgery is an option this time around.

"It's a definite possibility," D-backs manager A.J. Hinch said. "You can't rule anything out at this point. We've got to find a way to alleviate the pain. That's what the doctors are paid for. They'll give their opinions. He and I and the rest of this organization will come together and come with a plan of treatment."

The 2006 National League Cy Young Award winner has been on the disabled list since April 13, retroactive to April 7, because of the shoulder. He began to experience discomfort during Spring Training and made one start before going on the DL. He was scheduled to make a bullpen session on Friday but felt discomfort and returned to Phoenix for an evaluation.

Webb was not available for comment before Wednesday's game against the Rangers but is reportedly seeking a second opinion.

"We're going through the evaluation with the doctors and he's evaluating how many doctors he wants to see and getting as many opinions as possible," Hinch said.

Hinch briefly alluded to a big decision by Webb following Tuesday's 8-2 victory against Texas.

"I was referring to a decision on what type of treatment he is going to get, how serious this setback is, and playing out the next month of his life, what our next step is," the manager said. "He wants to get as much information as possible from as many doctors as he can so he can get his arms around what is causing this thing."
