Royals reliever Tim Collins underwent season-ending Tommy John surgery Wednesday after a second opinion of his injury revealed ligament damage in his elbow, per The Kansas City Star.
Collins made just 22 relief appearances for Kansas City last season while dealing with inflammation in the flexor tendon of his elbow, going 0-3 with a 3.86 ERA. The left-handed hurler is 12-17 with a 3.54 ERA over four MLB seasons.
