The Diamondbacks reassigned Hatch to minor-league camp Thursday, Alex D'Agostino of SI.com reports.
Hatch joined Arizona on a minor-league deal in January after he spent the 2025 season in the Royals and Twins organizations, logging a 5.82 ERA, 1.68 WHIP and 22:17 K:BB over 34 big-league innings between the two stops. After the right-hander was unable to win a spot on Arizona's Opening Day roster, he'll likely serve as a swingman at Triple-A Reno to begin the 2026 campaign.
