Gets Tommy John surgery Wednesday
Nationals manager Dave Martinez confirmed that Herz (elbow) underwent Tommy John surgery Wednesday in Dallas, Andrew Golden of The Washington Post reports.
Analysis
TalkNats.com was first to report earlier Wednesday that Herz had decided to undergo the season-ending procedure, though it wasn't immediately clear when the surgery would take place. Rather than scheduling surgery for a later date, Herz elected to have the operation performed by renowned orthopedic surgeon Dr. Keith Meister, whom he had recently visited for a second opinion on the partially torn UCL in his left elbow. Martinez noted that Herz's surgery didn't involve the insertion of an internal brace, so he'll likely be in line for a 14-to-18-month rehab process rather than a 12- or 13-month recovery. The 24-year-old is thus unlikely to be ready to contribute for the Nationals until around the middle of the 2026 season.
