A lot of eyes will be glued to the Seattle Mariners farm system in the next five days in the lead up to the 2025 MLB trade deadline, which is set for 3 p.m. PT on July 31. One of the Mariners most interesting prospects is starting to heat up for the organization's High-A Everett AquaSox.

On Wednesday, the Seattle Mariners acquired Josh Naylor from the Arizona Diamondbacks, likely taking them out of the Eugenio Suarez sweepstakes. Multiple teams, including the Tigers, could emerge as serious suitors for Suarez before the 2025 MLB trade deadline.

Suarez, on the back of an All-Star selection, is one of the hottest names on the market. With an eye-catching 36 home runs, good for second place in the National League, and 87 RBI, a bountiful number of MLB contenders are fighting for his services.

Though the move is a position upgrade for Seattle, it isn’t ideal for Naylor’s fantasy value — he was hitting .324 with five homers, 36 RBIs and a .855 OPS at Chase Field. Since 2021, Naylor hit a homer roughly once every 24 at-bats — including a career-high 31 last year with Cleveland when he hit one every 18 at-bats.

Jerry Dipoto has a longstanding reputation for jump-starting the Trade Deadline market, and the Mariners’ president of baseball operations indeed sparked this year’s traction, with the first major domino falling to Seattle on Thursday night.

The latest turn in the MLB trade market saw the Yankees get a third baseman, which could help the Seattle Mariners' push to land Eugenio Suárez.

The Seattle Mariners are open to trading versatile Gold Glove winner Dylan Moore, according to a report. Moore has struggled recently.
