Washington Nationals

Matt Waldron

Waldron has pitched 5.2 shutout innings since joining the Nationals in late August, but the team will now be without his services until at least Sept. 20 as he manages his chest injury. Zak Kent will come up from Triple-A Rochester to replenish Washington's reliever depth.

Drew Millas

Millas had a procedure in July when he first suffered the injury, but he'll undergo another one Friday because the finger didn't heal as hoped. It will be the third surgery the catcher has had on the finger since last August. There's no word on a timeline for Millas' rehab, but he should be healed well before spring training.

Orlando Ribalta

Ribalta landed on the injured list Monday with forearm inflammation, but the results of his tests confirmed that he isn't dealing with a structural issue. The Nationals will now shift their focus to making sure the 28-year-old gets enough time to rest and recover, and with the team well outside of the hunt for a postseason berth, there's no guarantee he pitches again this season.

PJ Poulin

Poulin had been on the shelf since July 19 due to a left flexor strain, and his move to the 60-day IL ensures that he'll remain out through Sept. 13. The southpaw's move to the 60-day frees up a spot on the 40-man roster for one of Yovanny Cruz and Jake Bird, two of the four players the Nationals acquired Sunday in the deal that sent Luis Garcia to the Yankees.

Mitchell Parker

Parker moved to the 60-day IL at the start of the month after being diagnosed with a Grade 3 UCL sprain, and the procedure will officially keep him out for the remainder of 2026 and most, if not all, of the 2027 campaign, as well.
