Ian Stewart has not ruled out exploratory surgery on his ailing left wrist. Stewart has had problems with the wrist for over a year, and it's surely been a factor in his struggles. A battery of tests last year revealed no structural damage, but he'll see a specialist Monday to get a second opinion. ''With all the MRI and X-ray results, nothing of major value came up in there where they said, 'We've got to get this done now,' or it would have been taken care of a long time ago,'' he said. ''But there have been instances where things didn't show up on those, and they can go in [surgically] and look and see if there are other things. I don't know if we'll go that route, but that's definitely a possibility.''
