Penn Murfee To Undergo Season-Ending UCL Surgery

The Mariners are dealing with a rash of significant pitching injuries, as relayed by Ryan Divish of The Seattle Times (Twitter links one, two and three). Right-hander Penn Murfee will undergo season-ending surgery on his ulnar collateral ligament. Meanwhile, pitching prospect Taylor Dollard will undergo season-ending labrum surgery. Additionally, lefty Marco Gonzales will be shut down for two weeks due to nerve issues in his elbow.

The news is a very unfortunate development for Murfee, who has been a strong presence in Seattle’s bullpen over the past two years. He debuted last season with a 2.99 ERA in 69 1/3 innings, striking out 27.9% of opponents against a 6.6% walk rate. This year, he’s struggled with control but nonetheless dropped his ERA to 1.29. He twice landed on the injured list due to elbow inflammation and will now have to go under the knife.

It’s not exactly clear exactly what kind of surgery Murfee will require, but he’s sure to face a significant absence either way. Full ulnar collateral ligament reconstruction, also known as Tommy John surgery, typical requires 14 to 18 months of recovery time. Even the internal brace alternative usually requires close to a year. That means that, in addition to missing the remainder of the 2023 season, Murfee will miss a chunk of the 2024 campaign as well.

More to come.
