KANSAS CITY, Mo. (AP) — Kansas City Royals reliever Greg Holland will undergo Tommy John surgery in Los Angeles on Friday.

The two-time American League All-Star had a drop-off on the mound this season, due in part to having pitched with a partially torn ulnar collateral ligament in his right elbow. He was shut down last week after pitching in 48 games with a 3.83 ERA and 32 saves.

At the time he was shut down, the team determined that surgery was the likely outcome for Holland, who said the elbow has bothered him since August 2014.

Dr. Neal ElAttrache of the Kerlan-Jobe Orthopaedic Clinic will perform Holland’s surgery, an MLB.com report said.

Holland returned to form for the Royals’ surprise run to the AL pennant but resisted an offseason MRI because he wanted to finish last season without knowledge of a potential tear, the report said.

An MRI on Aug. 31 detected the tear, but the 29-year-old wanted to try to pitch through it. He was replaced in the closer role by electric right-hander Wade Davis, who went 8-1 with an 0.97 ERA, 14 saves and 74 strikeouts in 64⅔ innings.
