New York Yankees right-hander Tommy Kahnle underwent Tommy John surgery Tuesday, the club announced Wednesday.

The typical timeline for recovery is 9-to-12 months for a reliever, notes Jon Heyman of MLB Network.

The Yankees placed Kahnle on the injured list with a ulnar collateral ligament injury at the end of July.

Kahnle only pitched in one game in 2020 and struck out three batters over one inning of work. The 30-year-old posted a 3.67 ERA with 88 strikeouts across 61 1/3 innings last year.
