The Mariners announced that right-hander Logan Evans has undergone surgery to reconstruct the ulnar collateral ligament in this throwing elbow with an internal brace. They announced his return timeline as 12 months, so he’ll miss the entire 2026 season.
It’s obviously rough news for both the club and Evans himself. The righty made his major league debut last year, tossing 81 1/3 innings for the Mariners, allowing 4.32 earned runs per nine. He struck out 16.9% of opponents faced, gave out walks at an 8.9% clip and induced grounders on 40% of balls in play. Instead of building on that in 2026, he’ll have to sit out the entire season while recovering. He’ll look to get back on track during the 2027 season. He’ll turn 26 in June of that year.
For the Mariners, they have now lost arguably their best optionable depth starter. Seattle has a strong core five in the rotation, including Logan Gilbert, George Kirby, Bryan Woo, Luis Castillo and Bryce Miller, but things drop off after that. That’s especially true now that Evans is out for the year.
The Mariners acquired Cooper Criswell from the Mets a week ago. He is out of options and projects to be a long reliever to start the season if he’s still on the roster by Opening Day and everyone else is healthy. Without Evans, the optionable starters on the 40-man roster are Emerson Hancock and Blas Castano. Hancock was the sixth overall pick in 2020 but he hasn’t lived up that pedigree with a 4.81 ERA and 15.6% strikeout rate in his career so far. Castano is 27 years old, has just one major league appearance under his belt and had a 5.19 ERA in Triple-A last year.
In terms of non-roster depth, lefty Jhonathan Díaz was outrighted this week but his transactions tracker at MLB.com indicates he elected free agency yesterday. That leaves Randy Dobnak, Dane Dunning and Casey Lawrence as non-roster options with some big league experience. Switch-pitching prospect Jurrangelo Cijntje is on the way but isn’t a near-term option since he hasn’t yet reached Triple-A and only has seven starts at the Double-A level. Perhaps the Evans surgery will lead the Mariners to add some more depth in the coming weeks.
Evans finished the 2025 campaign on optional assignment, so the Mariners could keep him there throughout 2026. Calling him up and placing him on the major league 60-day injured list would allow them to open up an extra 40-man roster spot but that would involve giving Evans a full year of big league pay and service time.
