Diamondbacks left-hander Andrew Saalfrank underwent shoulder surgery this morning and will miss the entire 2026 season, reports Steve Gilbert of MLB.com. The team has not yet announced the injury or provided further details but should do so in the near future. Presumably, Saalfrank sustained an injury late in his offseason program. Whatever the case, his subtraction from the bullpen is a tough break for a D-backs club that was already facing plenty of questions about its relief corps and has been working to bring some arms into the fold.
Saalfrank, 28, pitched 29 big league innings this past season and notched a pristine 1.24 earned run average in that time. That mark seems ripe for regression, as it was propped up by a .217 average on balls in play and 87% strand rate — neither of which seemed sustainable. Saalfrank fanned only 16.8% of his opponents, although his 12.2% swinging-strike rate suggests there could be more punchouts in the tank.
The left-handed Saalfrank issued walks at a respectable 8.8% clip and induced grounders at a solid 44.7% rate. Even if another sub-2.00 ERA wasn’t going to be in the cards, he still looked the part of a viable middle reliever at least — though Arizona used him in plenty of high-leverage spots last year after losing Justin Martinez and A.J. Puk to season-ending elbow surgeries.
More to come.
