Rhett Lowder (elbow, oblique) will begin a minor league rehab assignment on Saturday with Triple-A Louisville.
Lowder has been out all season recovering from elbow discomfort and an oblique strain. The 23-year-old prospect, who was selected seventh overall in the 2023 MLB Draft, is unlikely to contribute for Cincinnati this season (or postseason), but he appears on track to be a full-go for spring training.
