Kyle Harrison could move to bullpen as Brewers rotation struggles continue

The Brewers are considering moving Kyle Harrison to the bullpen after a difficult start against the Reds, MLB.com reported, as Milwaukee's rotation continues to face challenges heading into the final month of the regular season.

What happened

Milwaukee is weighing a role change for Harrison following his recent performance against Cincinnati. The exact timing and circumstances of the potential shift remain unconfirmed, but the club is evaluating the move as part of its response to ongoing rotation difficulties.

Why it matters

A rotation in distress forces difficult choices. Moving a starter to relief is not a demotion in modern baseball—it is a recalibration. The bullpen can absorb a pitcher's workload differently, and a reliever's shorter outing can mask fatigue or mechanical issues that accumulate over five or six innings. For a contending team, it is also a way to preserve depth and flexibility down the stretch.

Milwaukee's rotation troubles arrive at a moment when the club can least afford them. The Brewers lead the NL Central by a comfortable margin and sit in position to compete in October. A rotation that cannot deliver consistent quality starts in September—when every game carries weight and the schedule tightens—puts pressure on a bullpen and offense to carry more than their share.

The context here matters. Two days before this report, Jacob Misiorowski tied a career-worst five earned runs in a Brewers win over the Cubs. Manager Pat Murphy acknowledged possible fatigue after Misiorowski's August 21 outing, per the earlier reporting. A week removed from that game, the rotation's struggles have not resolved; they have prompted consideration of structural changes.

The Brewers have also been active on the roster front in recent days. Three days ago, the club designated Joel Kuhnel for assignment after his rehab window expired, reinstating him from the 15-day injured list. Two days ago, Milwaukee re-signed infielder Jonathan Ornelas to a minor league deal, sending him to Triple-A Nashville just before the postseason eligibility deadline. Five days ago, the Brewers activated JoJo Romero and called up a position player, likely Bo Naylor, with September 1 roster expansion. Six days ago, Abner Uribe was activated off the injured list ahead of a key rivalry series with the Cubs.

Those moves reflect a club managing its depth carefully as the calendar turns to September. The potential shift of Harrison to the bullpen would be another adjustment in that vein—a tactical response to immediate need rather than a long-term indictment.

The numbers

Harrison is scheduled to start Sunday's game at Great American Ball Park. The Brewers have not released a season line or performance data in the report, leaving the statistical case for the move unconfirmed. The decision appears to rest on recent performance rather than cumulative numbers.

Misiorowski's recent struggles offer a parallel. His velocity dips and fatigue signs, per the earlier reporting, suggest that the rotation's issues are not isolated to one pitcher. When multiple starters show strain in the same window, the club's options narrow. A bullpen move for one pitcher can buy time for another to rest or reset.

Where the club stands

The Brewers are 88-56 (.611), holding first place in the NL Central with a division magic number of 12. The club is on a two-game losing streak heading into Sunday's matchup at Cincinnati, where Harrison is the probable pitcher against Brady Singer. That game will offer an immediate window into whether the move to the bullpen is imminent or remains under consideration.

Following the Reds series, Milwaukee hosts the Chicago Cubs on Monday and Tuesday. Robert Gasser is probable for Monday against Matthew Boyd; Jacob Misiorowski is scheduled for Tuesday against David Peterson. The rotation's next three starts will reveal whether the club's recent struggles are temporary or symptomatic of deeper issues.

The division magic number of 12 means Milwaukee can afford to experiment. The Brewers are not fighting for a playoff spot; they are managing their way toward October with an eye on health, depth, and matchup flexibility. A bullpen role for Harrison, if it happens, would be part of that calculus—a way to keep him available without asking him to navigate a lineup three times through.

What we don't know yet

The timing of any move is unconfirmed. Harrison could remain in the rotation for his next scheduled start, or the Brewers could make the change immediately. The club has not announced a decision, and the report reflects possibility rather than plan.

It is also unclear whether this is a temporary adjustment or a longer-term role change. Relief appearances can serve as a reset for a struggling starter, or they can signal a permanent shift in how the club deploys him. The Brewers' next moves—and their communication about them—will clarify the intent.

The broader question is how Milwaukee addresses the rotation's struggles beyond Harrison. If Misiorowski's fatigue persists, if other starters falter, the club will need to decide whether to lean on its bullpen depth or adjust the rotation order. September roster expansion allows for additional arms—the active roster grows from 26 to 28 players starting September 1—but adding relievers does not solve a rotation problem. It only buys time.

What to watch

Sunday's game at Cincinnati will be the first test. If Harrison takes the ball as scheduled, the quality of his outing will inform whether the bullpen move accelerates. If he does not start, the announcement will confirm the change and raise questions about who fills the rotation slot.

The broader rotation picture matters equally. Misiorowski's fatigue, the recent struggles, and the September schedule all converge. The Brewers have the depth to weather a rotation adjustment, but the timing and execution of any move will shape how effectively the club finishes the regular season and enters October.

Milwaukee's division lead provides cushion, but October does not forgive a rotation that cannot hold up. The Brewers are managing toward that reality now, one potential bullpen move at a time.
