The Seattle Mariners could be facing a significant offseason loss, as projections from baseball insiders suggest the club may part ways with veteran third baseman Eugenio Suárez. Forecasts indicate Suárez could land a three-year contract worth approximately $70 million with the Arizona Diamondbacks, a move that would reshape both teams’ infield pictures heading into the new season.
Suárez, who spent the 2025 season in Seattle after being acquired via trade, played a key role in the Mariners’ offensive push during their playoff run. His power bat added much-needed thump to the middle of the lineup, and his presence helped stabilize the infield during a crucial stretch of the season. Despite that impact, signs are pointing toward Seattle being reluctant to match the type of long-term financial commitment Suárez is expected to command on the open market.
The Mariners were active at the trade deadline, acquiring both Suárez and Josh Naylor in an effort to bolster their offense for a postseason run. While Naylor has already re-signed with Seattle, Suárez remains unsigned, fueling speculation that the organization has made a calculated decision about where to allocate its resources. Retaining both sluggers at market value would significantly increase payroll, and Seattle appears poised to prioritize flexibility and long-term sustainability instead.
Analysts project that Suárez’s market value sits near $70 million over three years, an average annual salary just under $25 million. Given his consistent power production and track record as a run producer, that figure is seen as reasonable despite his age. At 34 years old, Suárez is likely seeking both financial security and a competitive situation, making a three-year deal an appealing middle ground for all sides.
Arizona has emerged as a particularly strong fit. The Diamondbacks are familiar with Suárez from his previous time in the National League and are in need of additional power to complement their dynamic core. A lineup featuring Suárez alongside players such as Corbin Carroll and Ketel Marte would give Arizona a deeper and more dangerous offensive profile, especially as the club looks to sustain postseason contention.
The Diamondbacks’ willingness to spend in pursuit of immediate competitiveness could give them an advantage in negotiations. While several teams could use help at third base, Arizona’s combination of roster need, payroll flexibility, and competitive trajectory makes them a logical landing spot. Adding Suárez would address a positional need while also sending a signal that the organization is committed to building on recent success.
From Seattle’s perspective, allowing Suárez to depart would reflect a broader philosophical approach. The Mariners have emphasized building around younger talent, strong pitching, and selective investments rather than long-term deals for aging veterans. While Suárez’s bat was impactful, the front office may view his departure as an opportunity to redistribute resources toward pitching depth, player development, or future offensive upgrades.
There is also the reality of timing. Seattle’s competitive window remains open, but the team must balance short-term ambition with long-term planning. Locking into multiple high-priced contracts for players in their mid-30s carries inherent risk, particularly for a club that has historically valued payroll flexibility. Letting Suárez walk would be a difficult decision, but not an unexpected one.
As of now, no official agreement has been announced, and Suárez’s future remains unresolved. Other teams could still enter the mix, and a return to Seattle has not been entirely ruled out. However, the growing expectation around the league is that his next contract will come from a new organization.
The situation has become one of the more closely watched storylines of the offseason. Whether Suárez ultimately lands in Arizona, remains in Seattle, or signs elsewhere will depend on how teams weigh performance, age, cost, and competitive timelines. Until a deal is finalized, the Mariners and Diamondbacks remain linked by a free-agent decision that could have lasting implications for both franchises.
