Logan Evans Undergoes Successful UCL Surgery

The Seattle Mariners have confirmed that pitcher Logan Evans has successfully undergone surgery to reconstruct the ulnar collateral ligament (UCL) in his throwing elbow. This procedure involved the use of an internal brace. As a result, Evans is expected to be sidelined for the entire 2026 season, with a projected recovery timeline of 12 months.

Impact on Logan Evans and the Mariners

This announcement brings disappointing news for both Evans and the Mariners organization. The right-hander made his major league debut in 2025. He pitched 81.1 innings with an earned run average (ERA) of 4.32, striking out 16.9% of batters faced and walking 8.9%. Furthermore, he induced ground balls on 40% of the contact he allowed.

While Evans had shown potential, his absence will be felt deeply. He will turn 26 in June 2027, when he looks to make a return to competitive baseball.

Seattle’s Pitching Options Moving Forward

Evans’ recovery will leave the Mariners with a gap in their pitching depth. They currently boast a strong rotation including Logan Gilbert, George Kirby, Bryan Woo, Luis Castillo, and Bryce Miller. However, the loss of Evans highlights a decline in their optionable starter depth.

• Acquisition of Cooper Criswell: Recently acquired from the Mets, Criswell is expected to serve as a long reliever if he makes the Opening Day roster.
• Other 40-Man Options: Emerson Hancock, the sixth overall pick in the 2020 draft, has a current ERA of 4.81 and a strikeout rate of 15.6%. Blas Castano, at 27 years old, has only one major league appearance and posted a 5.19 ERA in Triple-A last season.

In terms of non-roster options, Randy Dobnak, Dane Dunning, and Casey Lawrence provide some major league experience. Jhonathan Díaz was recently outrighted, allowing him to choose free agency.

Future Prospects

Looking ahead, the Mariners may consider bolstering their pitching depth soon. Jurrangelo Cijntje, a switch-pitching prospect, is not an immediate option, as he has not yet reached Triple-A.

As Evans continues his recovery, the Mariners will face strategic decisions regarding their roster. Placing Evans on the 60-day injured list could open up additional roster spots, though it will require managing his salary and service time.

As the 2026 season approaches, the focus remains on Evans’ recovery and the team’s ability to adapt to the new challenges in their pitching lineup.
