If all goes well during Irvin's upcoming throwing session, he could be cleared to head out on a rehab assignment coming out of the All-Star break. Irvin has been shelved since May 24 due to a right shoulder strain and will likely require multiple starts in the minors to build up his pitch count before re-entering the Washington rotation.

Waldichuk posted a 6.75 ERA and 1.50 WHIP in 9.1 innings over his five relief appearances with Washington before landing on the injured list April 13 after suffering a left forearm injury. The southpaw received a couple of medical opinions in the week following the injury and ultimately decided to undergo Tommy John surgery for the second time in just under two years, after he previously had the procedure in May 2024. Waldichuk also underwent a flexor tendon repair as part of the operation.

Parker is likely to undergo Tommy John surgery after being diagnosed with a Grade 3 UCL sprain in his left elbow, so the Nationals will stash him away on the 60-day IL for the rest of the season. The move creates space on the 40-man roster for Kyle Nicolas, who was acquired from Baltimore on Wednesday.

Lovelady retired the only batter he faced during an appearance Sunday versus the Orioles, but he apparently came out of the outing with an injury. The lefty reliever has filled a variety of roles for the Nationals this season from opener to occasional closer, but he'll now been shelved at least through the All-Star break.

Lord last pitched Sunday, when he was rocked for five runs over 1.1 innings. He could return when his 15 days are up or close to it if he is indeed merely dealing with tightness, but the Nationals could still need to send Lord for imaging to see if he has a strain.

It's the first bit of throwing the right-hander has done since he was diagnosed with a right flexor strain in late March. He will be brought along slowly in his rehab before being evaluated for a potential return to the Nationals' rotation.
