Mariners' Colt Emerson: Inks $95 million contract extension
Rotowire
The Mariners signed Emerson to an eight-year, $95 million contract extension Tuesday, Robert Murray of FanSided.com reports.
The deal includes a club option for a ninth year and can top $130 million if all incentives are reached. It's a record contract for a player yet to reach the majors. Emerson came close to winning a roster spot with the Mariners in spring training and now, with a new long-term contract, is a good bet to be promoted to the big club sooner rather than later, though he will remain at Triple-A Tacoma for now, per Ryan Divish of The Seattle Times. J.P. Crawford (shoulder) is on the 10-day injured list with a right shoulder injury that's nagged at him since the start of spring training and faces an uncertain timetable. Leo Rivas has been filling in at shortstop for Seattle, but the club could eventually look to Emerson to fill that void. Emerson, 20, slashed .285/.383/.458 with 16 homers and 14 steals over three levels in the minors in 2025 and is 5-for-14 with a home run in his first three games at Tacoma in 2026.

Mariners' Colt Emerson: Will open season in minors
Rotowire
The Mariners reassigned Emerson to minor-league camp Saturday.
Emerson entered spring as a contender to start at second base for the Mariners to begin the season, but fellow youngster Cole Young ended up running away with that role. Still, Emerson has held his own in Cactus League play, posting a .268/.340/.488 slash line with two home runs, eight RBI, nine runs and a stolen base through 18 contests. Emerson remains likely to make his MLB debut at some point during the upcoming campaign.

Mariners' Colt Emerson: Could need more seasoning
Rotowire
The Mariners could give Emerson more seasoning at Triple-A Tacoma following the acquisition of Brendan Donovan, Daniel Kramer of MLB.com reports.
Emerson will compete with Cole Young for a spot in the Mariners' lineup, but Young is considered the heavy favorite for the second-base job entering camp. The 20-year-old Emerson reached Tacoma in 2025, finishing with a .285/.383/.458 batting line with 16 home runs and 14 stolen bases over 130 games covering three levels of the minors. He should get an opportunity at the big-league level at some point during the 2026 campaign.

Mariners' Colt Emerson: Gets invite to MLB camp
Rotowire
The Mariners have extended Emerson an invitation to major-league camp during spring training.
Fellow top prospects Kade Anderson, Lazaro Montes and Ryan Sloan, among others, will join the 20-year-old infielder in big-league camp. Emerson has the best opportunity of all of them to break camp with the big club, as he is expected to be in the thick of the competition for the Mariners' third-base job. He slashed .285/.383/.458 with 16 home runs and 14 stolen bases over 130 games covering three levels of the minors in 2025.

Mariners' Colt Emerson: Will compete for Opening Day spot
Rotowire
The Mariners are expected to give Emerson "runway" to win an Opening Day roster spot, Adam Jude of the Seattle Times reports.
Most of Emerson's playing time in the minors has come at shortstop, but he's also played some second base and third base. With Eugenio Suarez entering free agency, the hot corner appears the most likely path for Emerson, who is expected to compete with Ben Williamson for the starting job. Emerson is just 20 and has only six games of experience at Triple-A Tacoma, but Jude notes that the Mariners considered putting Emerson on their playoff roster taxi squad. The left-handed hitter slashed .285/.383/.458 with 16 home runs and 14 stolen bases over 130 games across three levels in the minors in 2025.

Mariners' Colt Emerson: Adjustments paying off
Rotowire
Emerson is hitting .333 with three home runs, two steals and a 12:12 K:BB in his last 20 games for High-A Everett.
Emerson is slashing .265/.365/.411 with seven home runs, five steals and a 17.5 percent strikeout rate in 71 games for the AquaSox, but he's been making adjustments at the plate to better incorporate his lower half to get to more power while also introducing a toe-tap. Emerson's 51.4 percent groundball rate on the year is still something to monitor, but his stock is trending back up after a lengthy stretch where he struggled to hit for power.

Mariners' Colt Emerson: Walk machine for Modesto
Rotowire
Emerson has a .295/.457/.443 slash line with two home runs, one stolen base, 12 strikeouts and 16 walks in 16 games for Single-A Modesto.
