The Texas Rangers have released Tim Lincecum.

Lincecum was signed by the Rangers in March.

He has been working his way back from a blister that he suffered in spring training. His 30-day rehab period ended Tuesday, meaning the Rangers had to activate him, keep him on the disabled list indefinitely, send him to the minors or release him.

"Despite best intentions and a lot of hard work, we just didn't feel that it was the right move to bring him up right now," Jon Daniels said. "He was throwing OK, still kind of inconsistent with this command. We just were not of the mindset that it was going to be an upgrade on our relievers who are here. Our bullpen's been very, very good here."
