The Arizona Diamondbacks are signing Zac Gallen to a one-year deal, pending a physical.
Fantasy Impact
Gallen is expected to return to Arizona for his eighth season with the team. He has been excellent for the club throughout his career, posting a 3.61 ERA and 1.15 WHIP across 971 innings and earning an All-Star nod in 2023. Last season, however, he recorded a career-worst 4.83 ERA and saw his strikeout rate dip to 8.20 K/9 after finishing at 9.49 K/9 the year prior. He will look to rebound in 2026 and is going late in drafts, making him an intriguing option for fantasy managers expecting a bounce-back campaign.
The Diamondbacks are reportedly still exploring creative ways to re-sign free agent right-hander Zac Gallen.
Fantasy Impact
Gallen has also been linked to the Cubs, but his overall market has remained quiet. He remains the top available starter left with free agency around the corner.

Zac Gallen has rejected the one-yar qualifying offer from Arizona.
Fantasy Impact
Gallen was expected to decline the offer and will now remain a free agent. The move will set the Diamondbacks up to receive a future draft pick if Gallen signs with another team. The 30-year-old is expected to have multiple suitors as he looks to ink a multi-year contract.
The Arizona Diamondbacks extended a one-year, $22.05 million qualifying offer to starting pitcher Zac Gallen on Thursday. The move comes after Gallen finished what was described as the worst season of his MLB career in 2025.
Fantasy Impact
Gallen, who turns 30 next August, posted career worsts in 2025 with a 4.83 ERA, 15 losses, an 8.2 K/9, and a 1.5 HR/9. It is unclear what his market will be after the down year, but he could decline the qualifying offer in hopes of securing a long-term deal. If he signs elsewhere, Arizona would receive draft compensation.
