SEATTLE -- Mariners reliever David Aardsma is done for the 2011 season and likely longer after an MRI determined the closer needs Tommy John surgery on his right elbow.

The Mariners announced Aardsma's diagnosis on Friday night. He is scheduled for surgery late next week to be performed by Dr. Lewis Yocum.

Aardsma has missed the entire 2011 season. He was first sidelined by offseason surgery on his left hip. Once Aardsma started throwing, his rehab assignment at Triple-A Tacoma was cut short by a strained ligament. He spent the past two months try to rehab his elbow without surgery.

After an MRI on Thursday, it was recommended that Aardsma have the surgery.

Aardsma recorded 69 saves for Seattle the past two seasons.
