PHOENIX — The Arizona Diamondbacks have been hit with another bullpen injury, this time losing one of the relievers who helped stabilize the group during the second half of the 2025 season. Sep 26, 2025; San Diego, California, USA; Arizona Diamondbacks relief pitcher Andrew Saalfrank (27) throws a pitch during the seventh inning against the San Diego Padres at Petco Park.

Arizona Diamondbacks left-handed pitcher Andrew Saalfrank will miss the season after shoulder surgery, the team confirmed on Monday. The Diamondbacks did not say how Saalfrank got hurt, adding manager Torey Lovullo will address the injury on Tuesday. It's another hit for the pitching staff, which already is without relievers A.J. Puk and Justin Martinez, along with ace starter Corbin Burnes, for the first few months of the season.

This is a big blow for Arizona's bullpen.
