Right handed pitcher David Aardsma had an MRI exam yesterday on his elbow.

The results revealed that Aardsma will have to undergo Tommy John surgery. Aardsma will have the elbow ligament replacement procedure done in California late next week by Lewis Yocum, the Los Angeles Angels team physician. reports Greg Johns of MLB.com.

“Unfortunately my season is over,” the 29-year-old Aardsma tweeted on Friday. “I guess I wasn’t meant to pitch this year. I will undergo elbow surgery next week.

The Mariners closer already had to undergo surgery this year (January) to repair a torn labrum in his left hip, and hasn’t pitched in the Majors this season. He injured his elbow in May while still rehabbing from the hip surgery.
