The first major move of the 2025 MLB trade deadline arrived Thursday with a deal that sent Arizona Diamondbacks first baseman Josh Naylor to the Seattle Mariners, according to ESPN’s Jeff Passan.
Reportedly going back to the D-Backs are pitchers Brandyn Garcia and Ashton Izzi. Garcia made his MLB debut only three days earlier as a reliever, while Izzi is currently playing for the High-A Everett Aquasox. Garcia is ranked 13th on MLB Pipeline’s list of top Mariners prospects, while Izzi is 16th.

The D-Backs acquired Naylor last offseason in a deal that sent pitcher Slade Cecconi and a competitive-balance draft pick to the Cleveland Guardians. The move was made to replace outgoing first baseman Christian Walker, now of the Houston Astros, on an Arizona roster that still held playoff aspirations.
Naylor mostly fulfilled his end of the bargain, slashing .292/.360/.447 with 11 homers in 93 games, while the D-Backs did not. They currently hold a record of 50-53, good for fourth place in the NL West and 5.5 games back from a wild-card spot.
Arizona is now getting started on selling at the deadline, and the Mariners proved to be a match for Naylor.
