The Mariners’ starting pitching depth took a hit today, as the Mariners announced starter Logan Evans had UCL reconstruction surgery with the internal brace procedure. The surgery was performed by Dr. Keith Meister in Texas.
Evans, 24, made his debut last year and pitched in 16 games for the Mariners, accruing 81.1 innings. He started 15 of those 16 games, filling in for a Mariners rotation that suffered a spate of injuries. While Evans didn’t pitch in the playoff run, his contributions down the stretch helped the Mariners patch together a workable rotation while the regular starters healed, allowing the team to go on a deep playoff run.

The highlight of Evans’ season was a May 27th start against Washington where he went eight innings, the longest start by any Mariners pitcher all season. He surrendered just one run over those eight innings, a solo home run to James Wood. That game was also remarkable because the Nationals ran out an Oops! All Lefties! lineup against the righty Evans, who became the first Mariners pitcher in decades to face an all-lefty lineup.
Evans did spend some time on the IL this past season with right elbow inflammation, missing a month starting in mid-August after being diagnosed with VEO, or “pitcher’s elbow.” However, imaging at the time did not show structural damage. Evans first felt the pain on an August 14th start against Baltimore; he was moved to the IL and underwent a treatment plan of rest and cortisone injections. Evans returned to the club late in the season and threw three innings in a game on September 27th against the Dodgers, but was left off the playoff roster as the team progressed into October.
The timeline for recovery for an internal brace procedure is closer to 12 months than the 18 months of traditional Tommy John surgery, so if all goes well in recovery Evans could return as soon as spring training 2027. That doesn’t ease the sting of losing him for this year, though; Ryan just did Evans’s 40 in 40, dissecting the curious nature of Evans the first time vs. second time through the order, and what adjustments could be made to bridge the two performances. Now we will have to wait an extra year to find out the answer to that question.
The Mariners have done an admirable job building depth so far this season, with the addition of Cooper Criswell as well as some stalwart minor-league signings like Dane Dunning and Randy Dobnak. But Evans was a known quantity and proven performer, and the loss stings. This shifts pressure to Emerson Hancock to continue figuring it out at the big-league level, and also turns up the temperature somewhat on top prospect Kade Anderson, who is yet to throw a professional pitch but is almost certain to be a quick mover once he does. In the meantime, we wish Logan Evans well in his recovery, and hope to be back to two Big Logans soon.
