The Mariners and Diamondbacks are reportedly in agreement on a trade that’ll send Eugenio Suárez back to Seattle. The D-Backs are getting rookie first baseman Tyler Locklear, reliever Juan Burgos and minor league pitcher Hunter Cranton in return. The deal is expected to be officially announced on Thursday.
Seattle has made a Suárez reunion their top deadline priority. They’ll get their man, bringing back a two-time All-Star who combined for 53 home runs in a Mariners uniform between 2022-23. The M’s made the regrettable decision to trade Suárez away after the ’23 season. That netted hard-throwing middle reliever Carlos Vargas but was primarily motivated by a desire to shed the $13MM that remained on the third baseman’s contract at the time.
While Suárez started his Arizona tenure slow, he’s been one of the best hitters on the planet dating back to the middle of last summer. Over the past calendar year, Suárez has hit 53 home runs with a .273/.332/.589 slash line. He’s tied with Kyle Schwarber and teammate Cal Raleigh for third in MLB in homers during that stretch. Only Shohei Ohtani and Aaron Judge have hit more. Suárez went on such a tear in the second half last year that the D-Backs had an easy call to bring him back on a $15MM club option that once looked likelier to be bought out.
Suárez has shown no signs of slowing down at age 34. He has mashed at a .248/.321/.577 clip across 433 plate appearances. He and Raleigh are tied for the MLB lead with 87 runs batted in. Only Raleigh, Ohtani, Judge and Schwarber have more home runs. He’d led the American League in strikeouts during both seasons in his first run with Seattle. The 12-year big league veteran has trimmed his strikeout rate by a few percentage points in Arizona. There’s still a decent amount of swing-and-miss, but it’s not at the same rate that surely alarmed the M’s front office a couple years ago.
The Diamondbacks were on the fringe of the NL Wild Card race as recently as two weeks ago. A sweep at the hands of the Astros sealed their fate as deadline sellers. Houston’s division rivals have ironically been the big beneficiary. The D-Backs began their sell-off by dealing Josh Naylor to Seattle last week. He displaced Luke Raley as the starting first baseman. Suárez rejoins him as an impact corner infield tandem. It’ll likely push light-hitting rookie infielder Ben Williamson back to Triple-A.
Seattle now runs out a lineup including Raleigh, Suárez, Naylor, Julio Rodríguez, Randy Arozarena, Jorge Polanco and J.P. Crawford. Right fielder Dominic Canzone has mashed since being called up from Triple-A in early June. It’s the imposing lineup that Seattle has tried for years to build alongside their elite rotation.
The M’s are nevertheless far from guaranteed to make the playoffs. They’re currently tied with the Rangers for the AL’s last Wild Card spot and sit five games back of Houston in the division race. They’ve poked around the market for another late-inning reliever. Seattle added left-hander Caleb Ferguson to the bullpen on Wednesday evening, but he’s more of a complementary piece. If the Mariners have another big move in them, it’d probably be in the late innings.
The Mariners are taking on nearly $5MM in salary still owed to Suárez for the stretch run. They assumed almost $4MM on Naylor and close to $1MM for Ferguson. It’s a significant change from an offseason in which ownership left the front office without much budgetary flexibility. They’re all-in as they try to capitalize on Raleigh turning in one of the greatest seasons ever by a catcher. Suárez and Naylor might be the two best impending free agent hitters to move. The acquisition should be very well received in the clubhouse, as Suárez is a highly-regarded teammate with whom much of the roster is familiar.
Seattle gave up a trio of players to make that happen. Locklear, 24, is the most intriguing. He’s a righty-hitting first baseman who could replace Naylor as Arizona’s long-term answer at that position. Seattle took the Virginia Commonwealth product in the second round in 2022. The 24-year-old doesn’t have much big league experience. He appeared in 16 games last season, hitting .156 while striking out 20 times in 49 plate appearances.
Plenty of hitters struggle in their first look at MLB pitching. Locklear has posted excellent minor league numbers. He’s a career .291/.392/.502 hitter against minor league arms. That includes a huge .316/.401/.542 showing in Triple-A this season. Locklear has connected on 19 home runs in 434 plate appearances. Seattle just recalled him this afternoon to replace Raley, who went down with back spasms. Instead, he’s off to Arizona, where he’ll probably jump directly onto the MLB roster.
Burgos, 25, could also get an MLB look in the near future. Seattle called up the 6’0″ righty in late June. Burgos didn’t get much of a look over a three-week stint in the big league bullpen. He made four appearances, working 6 2/3 frames of three-run ball with eight strikeouts. Burgos showed a five-pitch mix built around a low-90s cutter and a mid-90s sinker.
He doesn’t have elite velocity for a bullpen prospect, but he has punched out an above-average 26.1% of batters faced over 31 innings between the top two minor league levels. Burgos has an absurd 0.87 earned run average in that stretch. Baseball America ranked him 25th among Seattle prospects, while he placed 17th at MLB Pipeline. Both outlets feel he’s a low-variance middle relief type.
Cranton is further off. Seattle drafted him in the third round last summer out of the University of Kansas. He was an underslot signee as a senior draft pick. MLB Pipeline ranked the 6’3″ righty as the #16 prospect in the Seattle system. He placed 23rd on Eric Longenhagen’s writeup at FanGraphs last month. He did not rank among BA’s top 30. Cranton has an upper-90s fastball and a slider. He was on the minor league injured through the end of June after being struck in the head by a comebacker during Spring Training, Longenhagen notes.
None of the three players are top-end prospects. The lack of a true headliner might come as a disappointment to Arizona fans, but it reflects teams’ general reluctance to give up elite young talent for rentals. The D-Backs added a pair of controllable players who could play meaningful roles as they try to return to competitiveness in 2026. In the meantime, they’ll eventually get their first real look at third base prospect Jordan Lawlar. Lawlar isn’t quite ready to return from a June hamstring injury that sent him to the Triple-A injured list, but he should get 4-6 weeks of everyday playing time to close the season.
Arizona has traded three impending free agents: Naylor, Suárez and Randal Grichuk. They’ll move at least one and possibly both of Zac Gallen and Merrill Kelly tomorrow. They could also try to move an outfielder or short-term relievers like the currently injured Shelby Miller or Kevin Ginkel. There’s plenty more to come from the Snakes over the next 18 hours.
