Mariners, D-backs Have Discussed Eugenio Suárez

The Mariners are among the teams with interest in Diamondbacks third baseman Eugenio Suárez, reports Jon Heyman of the New York Post. Adam Jude of the Seattle Times further reports that Suárez is viewed as Seattle’s top target in its well-known search for a corner infield upgrade. Jude adds that the Mariners and D-backs have held “preliminary” discussions regarding Suárez, whom Seattle views as a preferable option to Arizona first baseman Josh Naylor.

The 34-year-old Suárez has emerged as perhaps the most coveted bat on the trade market. He’s hitting .257/.328/.605 with 36 home runs on the season and has been among the sport’s elite power hitters dating back to his July renaissance in 2024. It’s easy to forget now, given how dominant Suárez has been at the plate over the past calendar year, but the beginning of the slugger’s time in Arizona was a disaster. He hit so poorly through the season’s first two-plus months that he began to lose playing time to young Blaze Alexander. That shift didn’t last long, as Suárez caught fire while Alexander stumbled.

Dating back to June 25 of last season, Suárez has come to the plate 751 times and slashed .281/.341/.605 with a whopping 60 home runs, 36 doubles and a triple. Only Aaron Judge and Shohei Ohtani have hit more home runs in that time (66 apiece). Suárez has bludgeoned left-handed and right-handed pitching alike. He’s being paid $15MM this season, with about $5.48MM of that sum yet to be paid out as of this writing. He’ll be a free agent at season’s end.

It’s not entirely clear yet that the Diamondbacks will trade Suárez at all, however. They swept the Cardinals in their first series coming out of the All-Star break, and though they lost to the Astros last night, they’re now just one game under .500 and 5.5 games back in the NL Wild Card chase. The Snakes have two more games against Houston before wrapping up their pre-deadline slate of games with three games in Pittsburgh and three games in Detroit.

Arizona general manager Mike Hazen has made clear that he hopes to avoid a sell-off and act as a buyer at this year’s deadline, but the team will have to perform well enough in this final push to justify that position. The Diamondbacks can also make a qualifying offer to Suárez if they hang onto him, so any trade return would need to eclipse the value of what would likely be a compensatory pick after the first-round of the 2026 draft.

If the Diamondbacks do end up seriously weighing offers for Suárez, a trade seems like a better outcome than that draft pick, however. The D-backs will likely take aim at contending again next season, and Suárez could net them some talent that can contribute either late this season or early next year. The draft selection would be a longer-term play, of course.

In theory, the Diamondbacks could even trade Suárez while still hoping to remain in contention this year. There’s no replacing his prodigious power output, but top prospect Jordan Lawlar could step into the everyday third base role down the stretch. Lawlar hasn’t hit at all in a tiny sample of 56 big league plate appearances, but he’s never been given any sort of regular playing time, either. He’s decimated Triple-A pitching this year, hitting .319/.410/.583 in 250 plate appearances. He’s currently on the minor league injured list with a hamstring strain but should return shortly after the deadline. Whether it’s this year or next, the 2021 No. 6 overall draft pick seems likely to get the opportunity to prove that he can be Arizona’s long-term option at the hot corner.

If the D-backs sell any veterans — Suárez or otherwise — they’re expected to focus on stockpiling young pitching. On the surface, that might sound like it makes Seattle a particularly appealing trade partner. However, the M’s aren’t going to trade an established starter like Logan Gilbert, Bryan Woo or George Kirby for a rental, and outside of young Logan Evans, most of their higher-end pitching prospects (e.g. Ryan Sloan, Jurrangelo Cijntje) are further down the pipeline.

That’s not to say the two sides can’t line up on a deal. At the end of the day, talent wins out, and if the Mariners offer a demonstrably better package than the Yankees, Cubs and other suitors, the positions of the prospects won’t be crucial. Arizona could look to flip some of those prospects for established big league arms in the offseason, after all. But if the D-backs are weighing two offers they deem to be comparable in value, it seems likely that they’d gravitate toward one that included some pitching talent that could be in the majors before terribly long.

The Diamondbacks lost Corbin Burnes to Tommy John surgery last month. He won’t pitch until late in the 2026 season, at the earliest. Zac Gallen and Merrill Kelly are free agents at season’s end. In-house arms like Blake Walston and Tommy Henry also had UCL surgeries earlier this season. Young righty Cristian Mena has been out since June with a shoulder strain. Top pitching prospect Yilber Diaz has had a disastrous season in the minors. Big league starters Brandon Pfaadt and Eduardo Rodriguez have both struggled. Adding some young arms is a sensible aim for the D-backs front office if they go the sell route in the coming week-plus.

The Mariners, of course, traded Suárez to the D-backs in the first place. That trade, following the 2023 season, was largely driven by a mandate from Seattle ownership to reduce payroll. The Mariners did come away from that swap with righty Carlos Vargas, who’s now a key member of the bullpen (47 innings, 3.83 ERA, 11 holds), but the front office surely would’ve preferred to hold onto the slugger and his vaunted clubhouse presence if not for those financial constraints. Mariners ownership is now reportedly willing to boost payroll, putting a reunion back on the table.
