Diamondbacks Face Offseason Decisions: Key Players Likely Out
8 Oct
Summary
- RHP Zac Gallen likely departing after two poor years and elbow injury.
- Kevin Ginkel's social media post suggests a likely departure from Arizona.
- Ryan Thompson's effectiveness dipped, likely favoring other arms for re-signing.

The Arizona Diamondbacks are preparing for an offseason of critical player decisions. With several roster members under contract through 2027, the team must navigate expiring deals and potential re-signings.
Right-handed pitcher Zac Gallen is nearly certain to leave Arizona. After re-signing ahead of 2026, he experienced a career-worst 2025 and continued struggles in 2026, posting a 6.07 ERA. Injuries and a move to the bullpen further complicated his season, making his return unlikely as he is not under contract for 2027.
Relief pitcher Kevin Ginkel has also signaled his departure through a heartfelt social media post. Despite a 4.12 ERA in 2026 and better underlying metrics, Ginkel experienced a late-season slump. His emotional farewell suggests he will not be re-signed by the Diamondbacks, despite his contributions, including to the 2023 World Series bullpen.
Another key member of the 2023 postseason, RHP Ryan Thompson, also appears to be on his way out. His effectiveness diminished in 2026, with his ERA rising to 4.43 and his sinker velocity dropping. Although a cheap deal is possible due to his late-season injury, the team likely prioritizes arms like Taylor Clarke or Jonathan Loaisiga over Thompson.
