White Sox shuffle Erick Fedde to bullpen after Luis Castillo acquisition, keeping Noah Schultz in rotation for now

The Chicago White Sox have begun reshaping their pitching rotation and bullpen after acquiring starter Luis Castillo from Seattle, with manager Will Venable announcing an immediate move for Erick Fedde. Instead of continuing as a starting pitcher, Fedde will be shifted to the bullpen as a stretched, multi-inning reliever, a role intended to keep late-leverage innings from draining the rest of the staff.

The practical effect of that decision is that the White Sox’s current starting plan remains intact at least in the short term. Noah Schultz, a rookie left-hander, is expected to stay in the starting five “for now,” according to the report attributed to Scott Merkin of. That suggests Chicago’s immediate priority is not a wholesale rotation overhaul, but rather a quicker redistribution of pitching responsibilities created by the Castillo addition.

The Fedde-to-bullpen move is also notable for how it fits the White Sox’s broader need for bullpen innings and flexibility. A multi-inning reliever is often used to bridge the gap between starter workloads and late-inning high-leverage matchups. With Castillo already in the mix as part of the rotation picture, the organization appears to be trying to protect pitching depth by turning Fedde into a weapon that can handle multiple frames rather than a single scheduled outing.

Strategically, a move like this can carry ripple effects. When a veteran starter takes on a reliever role, the team may reduce strain on other arms while also giving the manager a steadier option for long relief situations. In turn, that can impact how the rest of the bullpen is deployed, particularly in games where the starter is forced to depart early or where the team wants to preserve matchups for later innings.

Venable’s decision comes with an additional planning question still hanging over the staff: the report indicates the White Sox could trade for another starter. That possibility is significant because it points to a longer-term adjustment, not just a one-time reshuffling. If Chicago explores adding a rotation piece, the Fedde bullpen role may be part of a broader recalibration of how many starting pitchers the team wants to carry and how it intends to manage innings through the remainder of the season.

For Schultz, remaining in the rotation for now is both a vote of confidence and an opportunity to define his role with the club. Being kept in the starting five suggests the White Sox are willing to let the rookie’s development continue without immediately inserting another starter and pushing Schultz to the bullpen or out of the rotation mix.

What to watch next is whether the White Sox follow through on the reported interest in another starter, and how the bullpen is constructed once Fedde settles into his new assignment. The early answers may come quickly, because multi-inning relievers tend to receive consistent usage patterns once a team identifies the proper innings targets for that role.

Ultimately, the decision highlights how midseason trades can force teams to re-balance their pitching staff almost immediately. With Castillo now on board and Fedde moved into bullpen duty, Chicago’s management is trying to squeeze more functional value out of the roster rather than treating the rotation and bullpen as separate units.
