The right-hander received an injection in the AC joint of his right shoulder after an MRI came back negative Friday, and he'll spend at least a couple weeks on the shelf. Manager Terry Francona indicated Lowder is taking a break from mound work but will continue to throw, which could indicate his absence won't be a lengthy one. The Reds didn't make the transaction official prior to Sunday's matchup with the Astros, but the move should be announced in the near future.

Ferguson, who also threw Thursday, worked on back-to-back days for the Bats, which is typically a final box to be checked off for a reliever before coming off the injured list. The left-hander has made four appearances combined between Louisville and Double-A Chattanooga. The Reds' bullpen has fallen apart in May (8.47 ERA) and could use Ferguson as soon as possible.

Greene continues a slow ramp up while on the 60-day injured list after undergoing right elbow surgery in March. The Reds are targeting late May for the right-hander to throw a bullpen session, per MLB.com.

Reds manager Terry Francona noted Friday that Suarez's left oblique strain is about 50 percent better. Suarez will rest for a few days after Thursday's workout before ramping things back up. While the veteran slugger is improving, his return is not imminent. Nathaniel Lowe will continue to handle designated hitter duties for the Reds while Suarez is out.

A left calf strain has kept Staumont on the sideline since Opening Day. He made three rehab appearances at St. Paul and will remain with the Saints after allowing three runs across 3.2 innings, though he could return to the majors if the Twins find themselves in need of a fresh bullpen arm later in the season.

The transaction clears space on the 40-man roster for the addition of Tejay Antone, who was called up from Triple-A Louisville. Williamson landed on the 15-day IL last week with left shoulder fatigue and now won't be eligible for activation until late June.

Spiers was non-tendered by Cincinnati last week, but he'll remain in the organization on a minor-league pact. The right-hander is expected to miss most, if not all, of the 2026 season after having Tommy John surgery in late July, so it's likely a two-year minor-league contract.

Pagan aggravated a nagging hamstring issue on his first pitch of an appearance during Tuesday's 3-2 extra-inning loss to the Cubs and was placed on the 15-day injured list earlier Wednesday. With Pagan slated to miss at least a month of action, the Reds are likely to turn to Tony Santillan at closer, with Graham Ashcraft also potentially in the mix.
