Seattle Mariners prospect Colt Emerson, a 20-year-old shortstop, signed a record $95 million, eight-year contract last week, the biggest commitment ever for a minor leaguer yet to make his major league debut. Emerson is focused on the positives of the deal, which provides financial security for his family and allows him to continue developing as a player for the Mariners.

Why it matters

Long-term contracts for minor league players have become more common in recent seasons, as teams look to lock up top prospects before they reach the majors. Emerson's deal surpassed the previous record set by Milwaukee's Jackson Chourio, and it reflects the Mariners' high expectations for the young shortstop.

The details

Emerson, the 22nd overall pick in the 2023 draft, had a breakout year in 2025, hitting .285 with an .842 OPS, 16 homers, 28 doubles and 78 RBIs across three minor league levels. The Mariners first engaged in contract discussions with Emerson's agent during spring training, and the two sides quickly agreed on the record-setting deal that will keep Emerson in Seattle through the prime years of his career.

  • Emerson signed the $95 million, 8-year contract last week.
  • In 2025, Emerson had a breakout season in the minors.

— Jerry Dipoto, President of baseball operations, Seattle Mariners

“Given the security of being in the same city for the next eight years, (it) just allows me to stay the same guy. I mean, I'm never planning to change as a person, and just happy to go out there and be a winning ballplayer for the team and do whatever they need me to do.”

What’s next

Emerson will continue developing in the Mariners' minor league system, with the goal of making his MLB debut in the coming years and helping the team reach the World Series after coming up short last season.

The takeaway

Emerson's record-setting contract is a testament to the Mariners' faith in his potential, and it provides the young shortstop with financial security and the opportunity to focus on his development without the pressure of free agency looming. This deal could set a new precedent for top minor league prospects to be locked up before reaching the majors.
