MINNEAPOLIS -- The White Sox announced that left-hander John Danks will have exploratory surgery on his left shoulder on Monday, ending his season.
Danks has not pitched for the Sox since May 19 against the Cubs. He threw four innings in a minor league rehab assignment for AAA Charlotte on June 12 but wasn't right shortly after that start.
The White Sox Opening Day starter, Danks signed a five-year, $65 million extension during the off-season.
Last Friday, the Sox altered his throwing program in a last-ditch attempt at getting him back before the season ends.
"It's tough,'' Danks said Tuesday. "Obviously, this whole time, this has been the absolute last resort. We've been going on eight, weeks, and we haven't made improvements that we hoped and thought would be making. You do what you got to do. And we got to the point where we couldn't think but help start thinking about next year and cutting our losses this year and try to be ready by spring.''
A team of four doctors led by Tony Romeo and Greg Nicholson will perform the surgery at Rush Hospital. They will explore and determine what needs to be repaired.
The injury has been described as a strain. Trainer Herm Schneider said that MRI readings make it appear as though the strain has been healed, however. So it's obvious there is another, unknown issue.
The first-place Sox played the Minnesota Twins on Tuesday with a 1 1/2 game lead on the Tigers in the AL Central.
"These guys are playing well enough this year without me and getting [Francisco] Liriano [in a trade with the Twins] certainly helps and I definitely think there's plenty here now that me being out isn't going to kill this team. I'll be a cheerleader for the next two months, three months hopefully."
"It's disappointing for him, I know that,'' manager Robin Ventura said. "But in the long run, you find out what it is and take care of it. That's the biggest thing.
"With the way he was feeling and the timing of it, it's time to go in and find out what it is and take care of it.''
