Earlier this week, the Arizona Diamondbacks and Seattle Mariners came together on a trade that sent first baseman Josh Naylor to the Mariners in exchange for two pitching prospects.

Following this, Arizona continued to sell, opting to trade Randal Grichuk next. The Mariners have remained in the market to buy. There’s a chance these two teams will come together on another deal ahead of Thursday’s deadline.

Bob Nightengale of USA Today recently reported the Mariners were aggressively pursuing a trade for slugger Eugenio Suárez from the Diamondbacks. Suárez is in the final year of a $66 million contract. He played two seasons with the Mariners in 2022 and 2023.

“The Seattle Mariners, even after acquiring first baseman Josh Naylor from the Arizona Diamondbacks, are aggressively pursuing Naylor’s former teammate, All-Star third baseman Eugenio Suárez,” Nightengale wrote.

The Mariners desperately need more offense, and they have a hole at third base. With the addition of Naylor, it seems Seattle is one or two solid bats away from being a serious contender in the American League.

Seattle seems to be hyper-aggressive this year, which makes sense because it needs to take advantage of the generational season from Cal Raleigh.

Adding Suárez would be the right move, but there’s bound to be a lot of competition in a trade bidding war. The Philadelphia Phillies and Chicago Cubs make sense as suitors, though it’s unclear how aggressive they are. The Cincinnati Reds have checked in on Suárez, but it seems like a long shot.

Either way, the ball is in the Mariners’ court. If they’re willing to give up more talented prospects, Suárez could be joining Naylor in Seattle.
