The Yankees made several changes to Herring after drafting him (more sliders, better extension, higher arm slot) and the result looks like a stable backend starter despite 30-grade fastball velocity.
Herring spent two years as LSU’s most consistent long reliever (working as many as five innings) and was a draft-eligible sophomore in 2024. The Yankees made multiple changes to his delivery and pitch usage, which helped him dominate Low-A and earn a promotion after just eight starts. He had a 1.71 ERA combined at both levels at the time of the trade, though his K% dipped quite a bit after he was moved up to Hudson Valley. Herring’s fastball only averages about 90 mph, but lives off deception and riding life. Since turning pro, his arm slot has been raised, but Herring’s stride down the mound has gotten bigger and longer, and his extension was just shy of seven feet at the time of the trade. His loose, whippy arm action prevents hitters from seeing the baseball until release, and despite lacking anything close to average big league fastball velocity, Herring’s heater has generated above-average miss and chase so far this year.
With the Yankees, Herring also emphasized use of his slider, which has become his most-deployed pitch. It ranged from 80-85 mph in his final outing prior to the deal, and has tight late movement but lacks huge depth. It’s playing like an above-average pitch in pro ball. Herring didn’t really have a changeup in college, but he’s added one as a pro and is throwing it about 14% of the time. His feel for it isn’t bad considering he’s just begun using it, but it often cuts on him or finishes too high. A smooth on-mound operator, Herring looks the part of a starter even though he isn’t especially physical because of his mechanical grace. It’s impressive that he’s maintained his excellent college strike-throwing even though his delivery has been changed, and he projects as a high-floored backend starter.
