The Arizona Diamondbacks have secured Zac Gallen with a one-year contract worth $22.05 million, according to a source who confirmed the agreement to ESPN. The deal keeps the All-Star pitcher in the desert for the 2025 season after months of speculation about his future with the team.

Gallen, who has been the cornerstone of the Diamondbacks' rotation, was entering his final year of arbitration eligibility. The 28-year-old right-hander posted a 3.63 ERA across 32 starts last season, striking out 228 batters in 196 innings. His performance helped Arizona reach the playoffs for the first time since 2017.

The agreement provides both sides with flexibility. Gallen can test free agency after the season, while the Diamondbacks retain a proven starter without committing to a long-term deal. This approach mirrors how other small-market teams handle elite pitchers approaching free agency.
