Mariners top prospect Emerson to start 2026 in Triple-A

PEORIA, Ariz. -- Colt Emerson had a solid Spring Training, saw as much playing time as any Mariners position player and is a huge part of the club’s long-term plans.

But he will begin the 2026 season in the Minor Leagues.

Seattle on Saturday announced that it reassigned the 20-year-old infielder to Minors camp, ahead of its Cactus League game against the Cubs and one day after Emerson played in the Spring Breakout prospect showcase game.

Ranked the Mariners’ No. 1 prospect and MLB Pipeline’s No. 9 overall, Emerson went 11-for-41 with two homers, one double, one triple, eight RBIs, five walks and 10 strikeouts over 47 plate appearances -- good for a slash line of .268/.340/.488 (.828 OPS).

Emerson is expected to begin the season at Triple-A Tacoma, sources familiar with the club’s thinking told MLB.com, though it won’t announce the Rainiers' full roster until a later date.

Although the Mariners might have a need at shortstop if J.P. Crawford isn’t ready for Opening Day -- the veteran has been recovering from a sore throwing shoulder -- Emerson wasn’t legitimately considered as a temporary fill-in.

The club doesn’t view him as a placeholder and also didn’t want that to impede his player development by bringing him up for his MLB debut, potentially for a short stint, then sending him back down. Moreover, while he had a solid camp, Emerson didn’t necessarily force the front office’s hand by wowing his way onto the Opening Day roster.

The area where he shined most was with his glove, as Emerson made all the routine plays and even some flashy ones while playing in 13 games at shortstop and five at third base.

Crawford is making progress since receiving a cortisone shot earlier this week during a consultation with Dr. Keith Meister in Texas, but the Mariners won’t truly know if he’s ready to go until they break camp -- and potentially a few days after.

Leo Rivas is believed to be the frontrunner to fill in if Crawford needs more time, and Cole Young has started each of Seattle’s past two Cactus League games at shortstop, though that was more to get him reps there.

So, Emerson will report to Tacoma, where he finished last season over his final six games, then their two-game run in the Pacific Coast League playoffs. But it didn’t stop there, as Emerson was invited to T-Mobile Park to be included on the Mariners’ taxi squad ahead of the American League Division Series, even playing in a few scrimmages.

He climbed three Minors affiliates last season, and the next leap will be the big leagues -- potentially in 2026, as the club has said publicly. It just won’t happen for Opening Day.
