Seth Hernandez made the start for the Pirates’ Spring Breakout at LECOM Park in Bradenton, Fla., on March 20, 2026 — his first public appearance since Pittsburgh selected him in the first round of the 2025 draft. (mlb.com) Across his outing he threw 21 pitches with 11 reaching triple digits and three more at 99+, and five of his six offerings to Tigers prospect Max Clark clocked at 100 mph or faster; that plate appearance ultimately ended in a walk. (mlb.com) MLB Pipeline has Hernandez listed among the organization’s top prospects and in MLB’s Top 100 (he appeared as Pittsburgh’s No. 3 prospect and No. 29 overall in pipeline coverage), reflecting his rapid climb since the 2025 draft. (mlb.com) Scouts covering the showcase noted Hernandez mixed an elevated cutter with a 12-6 curveball and a feel-for changeup during the appearance, and TribLIVE reported he signed autographs before the game and later glanced at the radar readout. (triblive.com) In a dugout interview with MLB’s Jonathan Mayo, Max Clark said he’d followed Hernandez since high school and described that first pitch as “a beam of light,” a quote editors and analysts picked up while breaking down Clark’s on-field reaction. (mlb.com) Coverage linked Hernandez’s outing to the Spring Breakout’s history of eye-opening velocity displays — outlets pointed to prior triple‑digit showings from prospects like Paul Skenes in 2024 as part of the event’s emergence as a prospect showcase.
