Royals place LHP Amir Garrett (elbow) on injured list

The Kansas City Royals placed left-handed reliever Amir Garrett on the 15-day injured list on Friday.

Garrett, 31, has valgus extension overload in his left elbow. His IL designation is retroactive to Monday.

Garrett has no decisions and a 3.00 ERA in 23 relief appearances this season.

The Royals recalled right-hander Jackson Kowar from Triple-A Omaha in a corresponding transaction.

Kowar, 26, made one appearance for Kansas City earlier this season. He pitched 2 1/3 hitless innings against the Chicago White Sox on May 19.
