The Seattle Mariners are expected to be one of the aggressive teams at the trade deadline based on several reports. An MLB insider recently became the latest to buy into the Mariners being trade partners with a National League squad.

In a recent fan q&a story for The Athletic, Jim Bowden said Seattle should pursue Arizona first baseman Josh Naylor and third baseman Eugenio Suarez. Bowden pointed out the Mariners should be able to get deals done with their farm system:

The Mariners should do everything they can to make a trade with the Diamondbacks for third baseman Eugenio Suárez or first baseman Josh Naylor — or both for that matter. They have a strong enough farm system to get that done.

Seattle has been mentioned as potential partners with Arizona several times over the last few weeks, which makes sense given how often the two have been trade partners in the past. The Mariners are also rumored to be targeting corner infielders, which are needs Suarez and Naylor would both fill.

Seattle has nine prospects according to MLB Pipeline and eight according to Baseball America. Four of those prospects are middle infielders, two are outfielders, two are pitchers and one is a catcher.

Entering Wednesday, Naylor has scored 44 times in 83 games and has hit 18 doubles, a triple and 11 home runs with 58 RBIs. He's slashed .296/.357/.465 with an .822 OPS.

Suarez has scored 53 runs in 90 games this season and has hit 17 doubles and 28 homers with 74 RBIs. He's slashed .252/.319/.558 with an .877 OPS. Suarez earned the second All-Star nod of his career this season. He played for the Mariners from 2022-23.
