Shoulder to keep Rangers' Cordero out of WBC

SURPRISE, Ariz. -- Texas Rangers closer Francisco Cordero said Thursday a sore shoulder will keep him from competing for his native Dominican Republic in the World Baseball Classic.

"I'm really disappointed," Cordero said before morning workouts. "I've been waiting as long as I could to make the decision, but my shoulder just doesn't feel right."

Cordero has been battling a twinge in the back of his pitching shoulder that has limited him to throwing off flat ground instead of a mound this spring. He threw eight minutes Wednesday and said the pain was lingering.

"I'm not a fast starter in spring training, and I need to be careful," Cordero said. "I want the Dominican Republic to win as much as anybody back home, but I also want to be able to help the team."

Cordero is looking to regain his form as one of the best closers in the game. He had 49 saves and a 2.13 ERA in 2004 but slumped to 37 and 3.39 last season.

"I feel comfortable he made a decision in the best interest of his season and our season," general manager Jon Daniels said. "I know it was difficult for him."
