The Royals acquired Ryan Bergert from the Padres last summer hoping he could provide additional depth to their starting rotation. He impressed with a 4.43 ERA and 39 strikeouts in 40.2 innings over eight starts, but was sent to Omaha to begin this season. He exited his third start with an injury with right elbow discomfort.

The Royals announced today that Bergert successfully underwent Tommy John surgery this week to reconstruct his right ulnar collateral ligament. The typical timeline after Tommy John surgery requires 12-16 months of recovery.

Bergert had a 3.66 ERA in 76.1 innings in his debut season last year, split between the Padres and Royals. He was acquired with pitcher Stephen Kolek for catcher Freddy Fermin last July. Kolek is currently out with an oblique injury, although he has begun a rehab assignment in Omaha.

MLB.com reporter Anne Rogers also reports that Royals pitching prospect Ben Kudrna underwent an olecranon stress fracture fixation surgery on his elbow. The typical recovery time for that injury is 3-6 months. Kudrna had a 5.30 ERA in 105.1 innings in the minors last year, and made just one start for Omaha. MLB Pipeline ranks him as the #9 prospect in the organization.
