2026 Projections
2026 Fantasy Outlook
Herz entered last season coming off a promising debut campaign in 2024, when he posted a 4-9 record (19 starts) with a 4.16 ERA, 1.26 WHIP and 106:36 K:BB across 88.2 major-league innings. Unfortunately, after struggling in spring training and opening the 2025 season in Triple-A, his year was cut short in mid-April after undergoing Tommy John surgery. He's unlikely to be available to pitch for the Nationals until around the All-Star break in 2026, and there may not be a clear path to a spot on the major-league roster when he returns from his rehab assignment. When healthy in 2024, Herz finished in the top quarter of the majors in whiff rate (29.3 percent), strikeout rate (27.7 percent), xERA (3.29) and xBA (.207), though he was well below league average in GB rate (36.9 percent) and BB rate (9.4 percent). Those numbers make Herz an interesting stash option in the hopes that he makes his way back to the majors in 2026. Read Past Outlooks
In midst of throwing program
The Nationals announced Wednesday that Herz (elbow) is continuing to progress in his throwing program, Jessica Camerato of MLB.com reports.
Analysis
Back on Feb. 21, MLB.com reported that Herz had been playing catch at a distance up to 150 feet, but it's unclear if he remains limited to throwing off flat ground or if he's since graduated to throwing off a mound. Regardless, after landing on the 60-day injured list, Herz is slated to miss the first two months of the 2026 campaign -- and likely some additional time beyond that -- while he continues to work his way back from the Tommy John surgery he underwent April 16, 2025.

2025 Fantasy Outlook
Herz burst onto the scene for the Nationals in his third career start in June when he fanned 13 batters while yielding just one hit over six shutout innings against the Marlins. The left-hander added another double-digit strikeout game in July and finished his rookie season with an impressive 27.8 percent strikeout rate. The biggest knock on Herz as a prospect was his lack of control, as he's handed out free passes at an ugly 15.4 percent clip in the minors. He got that rate down to 9.4 percent in 19 starts with the Nats, which is still high but acceptable when paired with the swing-and-miss. Herz's four-seamer, changeup and slider made up 97 percent of his pitches in 2024 and all three offerings produced the exact same .283 xwOBA, which is excellent. There's blowup risk with the 24-year-old, but he has real upside if he can keep the walks to a dull roar.
