The Tacoma Rainiers have one week left in the season and are in contention for the PCL postseason. These factors have led to Emerson’s promotion, and he looks to help the team at shortstop during the final stretch of the campaign.
Per Justin Hollander, the Rainiers needed infield help, specifically shortstop, and they felt Emerson was the best fit. Tacoma has another week of games and possible PCL postseason https://t.co/uPd1ey5bfb

Emerson was drafted by Seattle with the 22nd overall pick of the first round in the 2023 MLB Draft. He The young infielder has shown elite talent during his time in the minors. Across two levels in 2025, Emerson has slashed .281/.380/.446 for a .826 OPS with 14 home runs, 26 doubles, 6 triples, 77 runs, 69 RBIs, and 13 stolen bases. He has also shown steady defense at the shortstop position, showing strong mechanics and making highlight plays.
The young shortstop has impressive tools that project well at the major league level. After moving to Triple-A, the next question is when he’ll break into the majors.
JP Crawford is the current shortstop for the Seattle Mariners, and he is under contract until the 2027 season, when he will become an unrestricted free agent. However, Emerson's quick path through the minors could allow him to make the MLB roster before the 2027 season. If Emerson proves that he can play at the Triple-A level during his stint with Tacoma, the front office will have no choice but to let him compete for an MLB spot during next season's Spring Training.
Keep an eye on Colt Emerson at the Triple-A level. As a key piece of Seattle's organization, he is putting himself in a position to make the major league roster in the near future.
