Diamondbacks Retain Zac Gallen After Trade Deadline

The Arizona Diamondbacks have chosen to keep their starting pitcher Zac Gallen, despite trade interest and a challenging 2025 season with a 5.60 ERA and a 7-12 record. General Manager Mike Hazen stated that no offers met the team's valuation, particularly given Gallen's impending free agency and the potential to receive a valuable draft pick if he declines a qualifying offer and signs elsewhere. Though Gallen's recent performance has been inconsistent, he remains a key figure for the Diamondbacks, having been instrumental in their 2023 World Series run and recognized as a clubhouse leader. The team has made several trades around the deadline, including sending Merrill Kelly to Texas and Eugenio Suarez to Seattle, but decided not to part with Gallen for less than the value they expect. Despite the down year, Gallen's prior success, including multiple top-10 Cy Young finishes and an All-Star appearance, influenced the decision to retain him. The Diamondbacks will look to Gallen to rebound in the final months of the season as they try to improve their standing in the NL West.
