The Cincinnati Reds have placed right-hander Tony Santillan on the 15-day injured list with a left oblique strain, retroactive to June 23, the team announced. The move means Santillan will be unavailable for at least the start of the IL period, and the team is now working from a thinner relief corps while it figures out the left side of its bullpen rotation over the coming weeks.

To fill Santillan’s spot on the active roster, the Reds recalled right-hander Zach McCambley from Triple-A Louisville. The roster transaction is designed to keep the bullpen stocked for day-to-day workload swings, especially as managers in MLB manage a delicate balance between setup usage, late-inning availability, and rest.

Santillan, 29, is the latest Reds relief pitcher to deal with a physical issue in a role where timing and availability matter. Because oblique strains can vary widely in recovery time, the Reds have not indicated a specific timetable beyond the IL designation, leaving the day-to-day plan to be shaped by how he responds during treatment and rehab.

The Reds’ next challenge is how to integrate McCambley into the mix immediately. A late-season recall typically comes with a defined bullpen role for the first stretch, but his exact usage will depend on how Cincinnati manages pitching matchups and recovery needs for the rest of the staff.

For the Reds, this is also a roster-management moment that affects more than just the next appearance. When a reliever goes on the IL, it can ripple into bullpen leverage planning, including who is available for consecutive games and who can pitch multiple days in a row if the schedule demands it.

Santillan’s placement on the injured list is official, but the reported length of absence is not. The IL window provides a baseline, yet oblique injuries often require more careful ramp-up than some other types of strains, so the team’s decisions in early July could reflect how the organization gauges his recovery.

Going forward, the story to watch is not only whether Santillan can resume throwing on the expected timeline, but also how Cincinnati continues to support its bullpen depth with the active roster spot filled by McCambley. The Reds will need that support to stay competitive in tight late-inning games, where bullpen availability can quickly change the outcome of a series.

Why It Matters

Bullpen stability is critical in MLB, and an IL placement for a reliever forces immediate changes to late-inning planning and leverage usage.
A left oblique injury can affect recovery pacing, meaning the Reds may have to manage bullpen staffing beyond the minimum IL window.
The McCambley call-up increases bullpen depth quickly, but his early role will depend on matchups and how Cincinnati allocates rest across the staff.
For Cincinnati, the move underscores the ongoing roster management challenge of keeping multiple relief arms available over a long season.
