Sox's Erick Threets to have surgery

CHICAGO -- Rookie Chris Sale is now the last left-hander standing in the White Sox bullpen after Erick Threets was lost for the season.

Threets, who is scheduled to undergo Tommy John surgery, tore his ulnar collateral ligament during the ninth inning of Friday's game against the Yankees. He did not give up a run in 11 appearances with the White Sox.

The 6-foot-5, 240-pounder has had an injury-plagued career ever since he was drafted by the San Francisco Giants in the seventh round in 2000. He missed the entire 2004 season with a shoulder injury and is expected to miss all of next season recovering from the surgery.

"This is going to be the last major setback I think," said Threets, who could be out as long as 12-18 months. "I'm going to work real hard to make this is the last one and if that doesn't work then I'm going to find another occupation. But I know for a fact I can get outs and I know for a fact I can be effective when we have leads. The timing of this is unfortunate. I feel a little embarrassed, actually."

The injury is another blow to the White Sox bullpen, who also lost left-hander Matt Thornton and right-hander J.J. Putz to the disabled list on Wednesday. Thornton is out with left elbow inflammation and Putz is out with tendinitis in his right knee.

Threets made just 10 major league appearances, all with the Giants, before coming to the White Sox this season.

"[A] very, very sad moment," manager Ozzie Guillen said. "This kid had some injuries in the past and now he's throwing the ball much better. I got the feeling when that happened, he knew because when I went out there and he didn't know what to say. I got the bad feeling that 'Wow, I think this kid know what he's got.'"

To take Threets' place on the roster, the White Sox recalled right-hander Carlos Torres from Triple-A Charlotte. Torres started for the White Sox on Aug. 3 at Detroit and gave up five runs on nine hits over six innings. He was 9-9 with a 3.52 ERA in 26 games, 24 starts, for Chicago's top farm club.
