Seattle Mariners shortstop Colt Emerson, a 20-year-old prospect with zero major league service time, has agreed to an eight-year, $95 million contract extension, sources confirmed to ESPN. This deal establishes the largest MLB contract ever for a player yet to appear in the majors, according to Spotrac. Emerson will remain at Triple-A Tacoma, where he's hitting .357 with a home run in his first three games, before potentially replacing J.

P. Crawford as the regular shortstop in 2027. The contract includes a ninth-year team option and a full no-trade clause, potentially reaching $130 million.

Emerson, the 22nd overall pick in 2023, slashed .285/.383/.458 with 16 homers and 78 RBIs across three minor league levels last season.
