Cubs reset their pitching plan after Edward Cabrera’s return, moving David Peterson to the bullpen

The Cubs’ internal pitching plan has shifted, with manager Craig Counsell moving David Peterson out of the starting rotation and into the bullpen. The change is tied to Edward Cabrera’s return to health and availability, which allowed the club to re-form the rotation without Peterson occupying a regular spot.

According to SB Nation Reacts coverage of the decision, Cabrera’s return meant he would be placed back into the rotation. That in turn created the opening for Peterson to go to the bullpen, a role change that can quickly affect how managers handle late-game matchups and bullpen workload across a week.

For Chicago, the practical impact is roster flexibility. A starter option in the bullpen can lengthen the leash for high-leverage innings, particularly if the Cubs want a left-handed look against specific hitters without burning a primary reliever. Peterson’s move does not eliminate his starting upside, but it does change the usage pattern and how often he is available across consecutive games.

The decision also reflects how quickly roles can evolve in-season when injuries resolve. When a pitcher returns from an injury, the rotation spot is often the first domino, and bullpen options become the balancing factor. In this case, Counsell’s comments as reported by SB Nation Reacts place Cabrera back at the top end of the rotation picture and shift Peterson to a relief assignment.

From a team-building standpoint, the Cubs are essentially choosing a “mix-and-match” approach rather than a permanent single role for every starter. That can matter over the final weeks of the regular season when each club’s bullpen depth and matchup planning tends to become more influential, and when managers are trying to manage fatigue while still chasing performance on specific days.

The immediate question is how quickly Peterson can translate his starter routine into bullpen execution. The best bullpen starters typically provide stable innings, but the transition often shows up in first appearances, sequencing, and pitch selection under shorter clocks. For the Cubs, monitoring how often Peterson is used in the middle innings versus higher leverage will clarify what his bullpen assignment is designed to accomplish.

As for what comes next, the most important watch point is whether Peterson’s bullpen role becomes a durable plan or a temporary adjustment while the rotation stays flexible. Equally, the Cubs will likely keep an eye on how Cabrera handles his return workload, because that can influence future rotation decisions and how bullpen pieces are deployed.
