Mariners infielder Colt Emerson will undergo season-ending surgery on his left wrist. Ryan Divish of The Seattle Times was among those who reported the news. Emerson is expected to be healthy for spring training next year, according to Divish. Emerson is already on the 10-day disabled list. He can be moved to the 60-day injured list whenever Seattle needs a spot on the 40-man roster. Emerson has had a newsworthy 2026 season, although not always in a good way. He entered the year as one of the best prospects in all of baseball. He apparently had a legitimate chance to break camp with the club, but was sent to the minors at the end of spring training. Although he was sent to the minors to start the schedule, the Mariners clearly saw him as a big part of the future. On the last day of March, Emerson and the Mariners agreed to an eight-year, $95 million extension. Despite signing that deal, Emerson initially remained in the minors on an optional assignment. He was finally promoted in May, but did not have much success in the major leagues. In his first 69 major league games, he stepped up to the plate 241 times. His 34.4% strikeout rate and 6.4% walk rate were poor numbers, contributing to a .190/.246/.335 line. On August 13, it was reported that Emerson would be moving back to the minors. However, the next day, he was placed on IL with tendon inflammation in his left wrist. According to Adam Jude of The Seattle Times, the injury had been bothering him for some time. While still in the minors in April, he received a cortisone shot and missed five games. President of baseball operations Jerry Dipoto expressed disappointment that Emerson had not been more forthcoming. “I wish he would have been a little more direct if it bothered him that much,” Dipoto said earlier this month. “I should have said something.” In the short term, the Mariners are still in the running here in 2026 and will have to continue to improvise at the shortstop position. JP Crawford moving from short to third to accommodate Emerson would be the logical solution. However, he is also on the injured list at the moment, coincidentally also due to inflammation of his left wrist. His return schedule is unclear. Meanwhile, Brock Rodden and Leo Rivas receive the majority of playing time there. Rodden had just been promoted when Emerson went on the disabled list. He has a solid .250/.321/.417 line in 28 plate appearances, but with a 34.7% strikeout rate and a .400 batting average on balls in play. Rivas has a career slash line of .201/.325/.258. That’s far from ideal as the M’s have a legitimate chance to win the division. Despite their 62-69 record, the Mariners are just three games behind the Astros and Rangers with just over a month left. From a broader perspective, the club surely hoped the long-term shortstop question had already been answered. Instead, it will remain a question until 2027. Presumably, the Mariners will feel that the wrist injury contributed to Emerson’s problems, but they still have no proof that he can be a viable major league player. “It … gives me some comfort understanding what happened during his time here,” Dipoto said when Emerson went on the injured list. “He just wants to compete. He wants to contribute. It’s hard to hit with a bad wrist, and it’s especially hard to hit with a bad wrist when you’re trying to play against a level of competition you’ve never played before. Colt Emerson has never had a problem with contact (in the minor leagues). He’s never had a problem with velocity, and we saw things happen that didn’t make sense. And this could really make sense.” Emerson made 600 plate appearances in the minors in 2025, at three levels. In them, he had a 17.5% strikeout rate and an 11.8% walk rate. He hit .285/.383/.458 for a wRC+ of 129. That’s what the Mariners were hoping for when they gave Emerson a deal just under nine figures. They may still get it in the long run, but they’ll probably have to remain in wait-and-see mode with Emerson for the time being. Looking to Seattle’s infield in 2027, Crawford is an imminent free agent. He could be re-signed, but is currently not part of the picture on paper. Josh Naylor will be at first base. Cole Young is having a good enough season to move back into the second base role next year. Brendan Donovan makes sense to be next year’s third baseman, although he is also having a year marked by injuries. He has good numbers but has been limited by various ailments to only 39 games so far. In an ideal world, an Emerson would make a full recovery and get things back on track by early 2027. He would arrive in the spring healthy and productive, and then hit the ground running in the regular season. But there are many ways they could go off the rails. Emerson’s recovery could suffer setbacks. It could take time to get back into good shape even after recovering, something that can happen with wrist problems. The 2027 season may not even start on time, depending on how collective bargaining negotiations play out. As the Mariners navigate the upcoming offseason, which is expected to be interrupted by a lockout, they will have to track all of those developments as they try to make their 2027 season less frustrating than the current campaign. Teams can’t communicate with players on their 40-man rosters during a lockout, so the front office likely won’t be able to track Emerson’s progress over the winter. Perhaps they’re looking for an eligible utility man at shortstop, someone who can cover Emerson’s position but also can get out of it if necessary. Maybe that’s Crawford. Perhaps the Mariners would have been searching for that type of player anyway, but this news presumably makes that search more important. Photo courtesy of Steven Bisig, Imagn Images
