The Diamondbacks signed Dubin (elbow) to a minor-league contract Dec. 19.
Dubin made 30 appearances between the Astros and Orioles in 2025, collecting a 5.08 ERA and 28:11 K:BB over 33.2 frames. The 30-year-old finished the year on the injured list with right elbow discomfort, and it's unclear whether he will have any restrictions at the beginning of spring training.
