The Arizona Diamondbacks aimed for a balance of retention and strategic acquisition during the 2026 offseason, successfully bringing back key pitchers Merrill Kelly and Zac Gallen while making a significant splash with the trade for third baseman Nolan Arenado. Totaling $56.3 million in guaranteed spending, with an additional $21.025 million deferred, the D-backs sought to bolster their roster without drastically increasing financial commitments.

Ketel Marte Trade Rumors

Despite significant trade speculation surrounding second baseman Ketel Marte, with interest from nine teams including the Tigers, Reds, Red Sox, Rays, Mariners, Pirates, Phillies, Giants, and Blue Jays, a trade ultimately did not materialize. General Manager Mike Hazen indicated a trade was “mostly unlikely” and set a deadline for negotiations. Source Marte’s acquisition of 10-and-5 status (10 years of MLB service, 5 with one team) granted him full no-trade protection, further complicating potential deals.

Payroll and Financial Considerations

The Diamondbacks’ total offseason spending reached $77.325 million, including deferred money. Team chairman Ken Kendrick expressed a commitment to investing in the team, stating the organization aims to allocate resources effectively based on fan support. Source The team’s projected payroll is approximately $195.2 million, a slight increase from the previous year’s $191.3 million.

Rotation and Bullpen Outlook

The re-signing of Gallen and Kelly addressed significant needs in the starting rotation, joining Eduardo Rodriguez, Brandon Pfaadt, and Ryne Nelson. Still, health concerns linger, with Kelly battling a back issue and Pfaadt experiencing side discomfort. Corbin Burnes is recovering from Tommy John surgery and is expected to return in late July or early August. Source

Reinforcing the bullpen was a priority, but the D-backs did not make substantial investments in new relievers. Paul Sewald and Taylor Clarke were added on modest deals, and the team hopes to identify bullpen contributors from waiver claims and minor league signings. Justin Martinez and A.J. Puk, both recovering from arm surgeries, are expected to return later in the season.

Position Player Notes

Jordan Lawlar is transitioning from infield to center field, adding complexity to his development. James McCann was re-signed as the backup catcher, and Carlos Santana is expected to share time at first base with Pavin Smith.

The Diamondbacks will require to assess their rotation’s health and performance during Spring Training, potentially leading to further bullpen additions before Opening Day. They may also explore trade options if the need for impactful changes arises as the season progresses. Source
