There's one day left until the 2025 MLB trade deadline, which takes place at 3 p.m. PT on July 31, and the Seattle Mariners reportedly have a lot of irons in the fire.

The Mariners knocked down the first domino in trade deadline season by acquiring first baseman Josh Naylor from the Arizona Diamondbacks on July 24. Since then, Seattle has been involved in discussions involving Diamondbacks third baseman Eugenio Suarez and several high-leverage relievers.

The Mariners added a piece to their bullpen by acquiring left-handed reliever Caleb Ferguson from the PIttsburgh Pirates on Wednesday, and they have one less competitor in the sweepstakes for Suarez.

The Cincinnati Reds acquired third baseman Ke'Bryan Hayes from the Pirates, also on Wednesday, which takes them out of the running for Suarez. The Reds were rumored to have interest in the 2025 All-Star. Suarez played for Cincinnati from 2015-21.

Per MLB insider Mark Feinsand, Seattle and the Chicago Cubs, Detroit Tigers and Philadelphia Phillies are still in play to acquire Suarez. The Milwaukee Brewers are also rumored to have interest in him.

The market for Eugenio Suárez is beginning to shape up with less than 30 hours until the Trade Deadline. Per sources, the Mariners, Cubs, Tigers and Phillies are considered the primary teams in the race for the All-Star third baseman.

Suarez has also played for the Tigers and the Mariners. It's been reported that Arizona is looking for an MLB player and top 100 prospects in return for him.

In two seasons with Seattle from 2022-23, Suarez has scored 144 times in 312 games and has hit 53 doubles, two triples and 53 home runs with 183 RBIs. He slashed .234/.327/.423 with a .751 OPS.

Suarez has scored 64 runs in 106 games this season and has hit 19 doubles and 36 home runs with 87 RBIs. He's slashed .248/.320/.576 with an .896 OPS.

If that’s Eugenio Suárez’s final Diamondbacks’ at-bat, it’s certainly been a hell of a run. pic.twitter.com/WILsZLnKmF
