EDGE Analysis

Garrett was placed on the injured list Friday after being diagnosed with left elbow valgus extension overload. He underwent an injection to help reduce the irritation and will be completely shut down from throwing for at least the next week. Jackson Kowar is up from Triple-A Omaha to provide much-needed depth for the Royals' bullpen.
