Arizona Diamondbacks’ rotation shuffles again as injuries hit, with Brandon Pfaadt viewed as a likely next answer

The Arizona Diamondbacks are dealing with a fresh injury setback, one that again forces the franchise to rethink how it will cover innings and matchups as the season moves deeper. Yahoo Sports highlighted that Nelson and Soroka are out, adding pressure to an already strained pitching plan and turning the question from “who is ready” to “who can be ready first.”

In the immediate aftermath, the Diamondbacks’ most practical need is straightforward. When the bullpen has to cover late innings too often, games can become harder to manage, and the margin for error shrinks. Yahoo’s discussion framed the timing as urgent, describing a scenario in which the club needs a pitcher who can realistically handle roughly five to seven innings, not just specialist work, because they have to absorb starts that no longer exist.

Brandon Pfaadt is one of the names that has entered that conversation as a possible next step. Yahoo Sports argued that his longer-term outlook is as a starter, even if his current role is more situational than locked-in at this point. The piece also suggested that the Diamondbacks have more reason to lean on Pfaadt now because other options have not yet received the same opportunity at the major league level.

That distinction matters for roster logic. An organization can carry depth, but if those arms have limited experience facing lineups in full-start contexts, managers often end up protecting the bullpen with shorter leashes and more frequent reliever turns. By contrast, a pitcher who can take on a larger workload can reduce game-to-game volatility, even if his results are not perfect. In other words, the target is innings and structure, not just “someone who can get outs.”

Yahoo’s analysis also described a transition that would be familiar to baseball teams when injuries pile up: the move from mop-up assignments in blowouts to mop-up work that effectively functions as rotation duty. That is a subtle but important difference. Mop-up is often about preserving the bullpen in low-leverage situations, while rotation duty forces a starter to face multiple times through a lineup and to make adjustments over a longer stretch.

The Diamondbacks’ broader challenge, then, is not simply replacing one arm. It is maintaining a usable pitching framework across starts, leverage innings, and travel days, without forcing the staff into a constant crisis mode. When Nelson and Soroka are out, that instantly changes how many pitchers the team can trust for multiple innings and how often relievers can return for fresh work rather than extended stretches.

What to watch next is how Arizona balances urgency with fit. If Pfaadt becomes the most direct “next man up” option, the key questions will be how long he can stay out there, how quickly the team stabilizes its bullpen usage patterns, and whether any additional pitching moves follow to keep the workload from concentrating too heavily on a few arms.
