Zac Gallen Finalizes $22.025M One-Year Deal with Diamondbacks

Zac Gallen has finalized a one-year, $22.025 million contract with the Arizona Diamondbacks, returning to the team after declining a qualifying offer. The 30-year-old right-hander was unable to find a long-term deal this offseason. He is coming off a career-worst 2025 season, posting a 4.83 ERA, 1.26 WHIP, and allowing 31 homers. Despite the performance dip, he has maintained health, making at least 31 starts in three of the last four years.
