The Diamondbacks announced a new seven-year contract with star second baseman Ketel Marte. It’s a reported $116.5MM guarantee that comes with $64MM in new money. Marte, who had already been under contract for three seasons, is now signed through 2031. He can opt out of the deal after the 2030 season, when there’ll be at least $11.5MM remaining. There are also $33MM in escalators and performance bonuses for the QC Sports client. Marte receives a five-team no-trade clause, though that’ll become moot when he gets 10-and-5 rights early in the 2026 season.
The contract takes effect this year and breaks down as follows: $14MM in 2025 ($5MM of which is deferred), $15MM in ’26, $12MM in ’27, $20MM in ’28, and $22MMM per season between 2029-30. Each top-three MVP finish would boost the following year’s salary by $3MM; it’d go up by $2MM if he finishes between fourth and seventh in MVP voting. The deal also includes $2.5MM annually from 2026-31 in plate appearance incentives.
The news surely comes as a delight to fans in Arizona. The face of the Diamondbacks franchise first flashed superstar potential back in 2019, when he was an All-Star and finished fourth in NL MVP voting after slashing .329/.389/.592 (150 wRC+) in 144 games. In the years since then, he’s generally been an above-average player but not necessarily a superstar, slashing .275/.347/.462 with a wRC+ of 118 from 2020 to 2023. That narrative changed in 2024, however, as Marte rediscovered his MVP-caliber form during his age-30 season with a phenomenal .292/.372/.560 (151 wRC+) slash line that earned Marte his first career Silver Slugger award, a second All-Star appearance, and a third place finish in MVP voting behind Shohei Ohtani and Francisco Lindor.
That’s the sort of elite production that makes for a phenomenal building block, so it’s not exactly a surprise that Arizona brass were interested in extended Marte’s stay with the club and making him a Diamondback for life. The club has often been aggressive about extending its top players under Mike Hazen, with this latest deal for Marte standing as the tenth extension agreed upon since he took over baseball operations in fall of 2016. It’s also the fourth of 2025, joining agreements the club reached with shortstop Geraldo Perdomo, reliever Justin Martinez, and right-hander Brandon Pfaadt.
More notably, it’s also the third extension of Marte’s career. His first came back in 2018 when he was a pre-arbitration player. The switch-hitter was guaranteed $24MM by that first deal, which ran through the end of his expected team control window but also afforded the Diamondbacks two option years on what otherwise would’ve been Marte’s first two years of free agency. Marte’s second deal came about just before the 2022 season began, ahead of his final year before those options would’ve kicked in. That deal overwrote those two option years and guaranteed Marte $76MM for the 2023-27 seasons, and also included a club option for 2028.
The second deal ended up covering just two seasons, as it has now already been overwritten to extend Marte’s stay in Arizona through at least 2030, with a player option that could push the deal into 2031. Given the fact that Marte was already under team control through the end of his age-34 season, it’s at least somewhat surprising that the Diamondbacks would decide to commit to their second baseman’s mid-30s this far ahead of time. After all, the club very easily could’ve waited to see how Marte would perform over the next two or three seasons before opening discussions with Marte prior to the 2028 season, when they would likely exercise their club option over his services.
With that being said, the deal not only extends Arizona’s years of control over their star, but also restructures his existing contract. Marte was slated to earn $50.8MM over the next three seasons on his existing contract. That number drops to just $41MM with his new deal, saving the club nearly $10MM over the next three seasons and $5MM in 2025 alone. That also does not factor in the $46MM in deferred money in the deal, which cuts down the amount of money owed to Marte in the short-term even further.
That the Diamondbacks would seek a restructured deal with Marte in order to save a bit of money in the short-term is understandable considering that the team is deep into uncharted financial waters. According to Cot’s Baseball Contracts, the club opened the 2025 season with a payroll of nearly $187MM. That’s an increase of $24MM over 2024, which was already the highest payroll in franchise history by more than $30MM. The club’s aggressiveness this winter in adding Corbin Burnes and swinging a trade for Josh Naylor was certainly admirable, but it’s long appeared likely that the Diamondbacks were likely stretching the limits of owner Ken Kendrick’s comfort zone.
If Arizona is facing the upper limits of its baseball operations budget, that could also explain the club’s reported insistence on suitors for struggling southpaw Jordan Montgomery eating at least $13MM of his $25MM salary for 2025 in trade talks as well as the club falling short in its pursuit of a top-flight closer this winter. Perhaps this restructured deal with Marte will offer them a bit more breathing room to work with at the trade deadline during an important 2025 season. After the current campaign, Montgomery and Naylor are slated to be joined by Zac Gallen, Merrill Kelly, and Eugenio Suarez in departing for free agency. That’s a lot of significant players who will need to be re-signed or replaced to avoid a step back in 2026, and it’s possible today’s restructuring of Marte’s deal could help the club fill those upcoming holes as well.
Mike Rodriguez first reported last night that the D-Backs and Marte were working on a new nine-figure contract. Nick Piecoro of the Arizona Republic was first on the $116.5MM guarantee, the $46MM in deferrals, the 2031 player option, and the salary structure. ESPN’s Jesse Rogers had the $11.5MM option value and the $149.5MM maximum after escalators. Piecoro had the escalator specifics.
