2/14/2026, 4:57:12 AM

Key Details of the Contract

The Arizona Diamondbacks have reportedly finalized a one-year contract with pitcher Zac Gallen, valued at $22.025 million. This agreement comes after Gallen declined a $22 million qualifying offer from the team earlier in the offseason. The contract includes a deferred payment of $14 million, as reported by multiple sources, including ESPN's Alden Gonzalez and The Athletic's Ken Rosenthal.

Gallen's Recent Performance

Zac Gallen, a 30-year-old right-handed pitcher, experienced the most challenging season of his career in 2025, finishing with a 4.83 ERA and allowing 31 home runs, which ranked among the highest in Major League Baseball. Despite these struggles, Gallen showed signs of improvement towards the end of the season, achieving a 3.32 ERA in the latter part of the year. Over his seven-year career, he has maintained a career ERA of 3.58 and a FIP of 3.65.

Background and Context

Gallen has been a significant figure in the Diamondbacks' rotation since being acquired from the Miami Marlins in July 2019. He was drafted by the St. Louis Cardinals in 2016 and has since developed into a key player for Arizona, even finishing third in the National League Cy Young Award voting in 2023. His performance contributed to the Diamondbacks' unexpected run to the World Series that year.

Official Statements & Responses

Diamondbacks General Manager Mike Hazen indicated that the team is still actively seeking to bolster both their starting pitching and position player depth. The return of Gallen is seen as a strategic move to enhance the rotation, especially as the team awaits the recovery of ace Corbin Burnes from Tommy John surgery.

Criticism & Opposition

While the Diamondbacks are optimistic about Gallen's return, some analysts have expressed concerns regarding his recent performance and the potential risks associated with his contract. Critics argue that investing heavily in a player coming off a poor season could be a gamble, especially in a competitive division that includes strong teams like the Los Angeles Dodgers and San Diego Padres.

What's Next

As the Diamondbacks prepare for the upcoming season, they aim to solidify their roster further. The team has also signed reliever Paul Sewald to a one-year, $1.5 million contract, indicating their commitment to enhancing their bullpen. The Diamondbacks will kick off their season against the Los Angeles Dodgers on March 26, 2026.
