Herz (elbow) struck out two and allowed one hit and two walks over two scoreless innings in a rehab start Thursday with Double-A Harrisburg.

After Herz underwent Tommy John surgery in April 2025 and then suffered a left flexor strain this past June, the Nationals have been having him ramp up slowly. Through three outings between Single-A Fredericksburg and Harrisburg, the southpaw has yet to permit a run, but he's been limited to five total innings in those appearances. The 33 pitches he threw Thursday marked a new season high for Herz, but he would need to push that count up to the 70-80 range before becoming a viable option for the Washington rotation.

Herz (elbow) struck out two over two perfect innings in his rehab start Friday with Double-A Harrisburg.

Since restarting his rehab assignment earlier this month after recovering from a flexor strain, Herz has piled up five strikeouts over three scoreless frames. Before bringing Herz back from the 60-day injured list, the Nationals are likely to have him build up gradually over at least two more rehab appearances, as the left-hander previously underwent Tommy John surgery last April. Depending on how he fares in subsequent outings in the minors, Herz could have a spot in the rotation waiting for him once he's activated.

Herz (elbow) will resume his rehab assignment with Single-A Fredericksburg on Saturday, Spencer Nusbaum of The Athletic reports.

Coming back from Tommy John surgery, Herz had made three rehab starts before he encountered a setback in late June with a left flexor strain. The southpaw logged a 1.17 ERA, 0.52 WHIP and 11:0 K:BB in 7.2 innings on his rehab assignment before getting hurt, so he'll be looking to pick up where he left off. Herz might not rejoin the Nationals until September, if at all, this season, as he still has a ways to go in terms of rebuilding stamina.

It's a significant setback for Herz, who has been working his way back from April 2025 Tommy John surgery. The left-hander posted a 1.17 ERA, 0.52 WHIP and 11:0 K:BB in 7.2 innings covering his first three rehab starts, potentially setting him up for activation around the All-Star break. After suffering the flexor strain, however, Herz will be out indefinitely.

Nationals manager Blake Butera said that Herz (elbow) won't make a rehab start Sunday with Single-A Fredericksburg as planned after experiencing forearm tightness following his most recent outing Tuesday, Spencer Nusbaum of The Athletic reports.

Just over 15 months removed from Tommy John surgery, Herz had looked good over his first three rehab starts between Fredericksburg and the rookie-level Florida Complex League, turning in a 1.17 ERA, 0.52 WHIP and 11:0 K:BB in 7.2 innings. The southpaw appeared to be tracking toward consideration for a spot in the big-league rotation upon his return from the 60-day injured list, but the setback will muddle his outlook. Herz will likely be shut down at least a couple of weeks before resuming mound work.
