Bloomquist underwent the surgery on Friday morning. Manager Lloyd McClendon said Bloomquist will be on crutches for the next six to eight weeks, but should be available for spring training.
Bloomquist was injured running out an RBI groundout on July 23 against the Mets. He was scheduled to have a scope that revealed the extent of the damage in his knee. Seattle was hopeful the damage was minimal and Bloomquist would be back this season.
Bloomquist hit .278 in 47 games while appearing at seven different positions for the Mariners.
