Mariners Bring Back Eugenio Suárez in Trade With Diamondbacks

The Seattle Mariners are reuniting with a familiar face. They’ve agreed to a trade with the Arizona Diamondbacks that brings third baseman Eugenio Suárez back to the Pacific Northwest. Arizona will receive rookie first baseman Tyler Locklear, reliever Juan Burgos, and minor league pitcher Hunter Cranton in return. The deal is expected to become official on Thursday.

Suárez Returns After Red-Hot Stretch

Bringing back Suárez was Seattle’s top trade deadline priority, and they got it done. The two-time All-Star played for the Mariners in 2022 and 2023, hitting 53 home runs across those two seasons. Seattle traded him away after last year in a cost-cutting move that saved $13 million and brought back reliever Carlos Vargas.

That decision didn’t age well.

Suárez started slow in Arizona, but he’s been one of baseball’s best hitters since mid-2023. Over the past year, he’s slugged 53 home runs and posted a .273 batting average with a .589 slugging percentage. Only Shohei Ohtani and Aaron Judge have hit more homers in that time. His second-half surge last year made Arizona’s decision to pick up his $15 million option this season an easy one.

At 34, Suárez hasn’t slowed down. He’s hit .248 with 28 home runs and 87 RBIs so far in 2025 — tied for the MLB lead in RBIs with teammate Cal Raleigh. He still strikes out, but not as much as he did during his first stint in Seattle, when he led the American League in that category both years.

Seattle’s Lineup Looks Stronger

This deal is Seattle’s second trade with Arizona in just over a week. Last week, the Mariners acquired Josh Naylor, who has replaced Luke Raley at first base. Now Suárez slots back in at third, likely sending rookie Ben Williamson back to Triple-A.

Seattle’s new-look lineup includes Suárez, Naylor, Raleigh, Julio Rodríguez, Randy Arozarena, Jorge Polanco, and J.P. Crawford. Outfielder Dominic Canzone has also been hitting well since his call-up in June. It’s the kind of balanced, power-packed lineup the Mariners have wanted for years to support their elite pitching staff.

Still a Tight Race in the AL

Despite the upgrades, the Mariners have work to do. They’re tied with the Texas Rangers for the final AL Wild Card spot and trail the division-leading Astros by five games.

Seattle also added lefty reliever Caleb Ferguson on Wednesday. He’s a useful piece, but the front office may still look for another late-inning arm before the deadline.

Ownership has taken on nearly $10 million in salary over the past week between Suárez, Naylor, and Ferguson — a major shift from a quiet offseason. The team is clearly all-in as they try to take advantage of Raleigh’s incredible season behind the plate.

What Arizona Gets in Return

The Diamondbacks are retooling after falling out of the playoff picture following a sweep by the Astros. This is their third trade in a week, following the deals that sent Naylor and Randal Grichuk away.

In return for Suárez, Arizona gets three players — none considered elite prospects, but all with upside.

Tyler Locklear (1B):

Locklear is the most notable piece. Drafted in the second round in 2022, the 24-year-old has torn up Triple-A this season, batting .316 with 19 home runs. He struggled during a brief stint in the majors last year, hitting just .156, but he could develop into Arizona’s long-term first baseman.

Juan Burgos (RHP):

The 25-year-old reliever made four appearances for Seattle this year, striking out eight batters in 6.2 innings. He’s known for a solid five-pitch mix, including a mid-90s sinker. Burgos has dominated the minors this year with a 0.87 ERA. He likely fits into Arizona’s bullpen plans soon.

Hunter Cranton (RHP):

Cranton, 22, was a third-round pick last year out of Kansas. He’s further away from the big leagues, especially after taking a line drive to the head in Spring Training. Still, his upper-90s fastball and slider give him solid potential.

What’s Next for the D-Backs?

This trade continues Arizona’s deadline sell-off. They may also move pitchers Zac Gallen and Merrill Kelly before the deadline ends. Outfielders or injured relievers like Shelby Miller and Kevin Ginkel could be on the block, too.

Suárez’s departure could open the door for top third base prospect Jordan Lawlar once he returns from a hamstring injury. The 2021 first-round pick is expected to get extended playing time in the final month of the season.
