Elite velocity is on the rise, and not just in the pro game.
Three high school pitchers from the 2025 class have already hit triple-digit velocity to join an exclusive—but growing—club of high-octane prep hurlers.
California righthander Seth Hernandez, the top-ranked high school pitcher in the class, has gotten his fastball up to 100 mph on multiple occasions. Just last week at USA Baseball’s National High School Invitational, New York righthander Miguel Sime Jr. also touched 100 mph while Illinois lefthander Jack Bauer has run his fastball up to 102 mph to become the hardest-throwing high school lefthander of all-time.
It’s always big news when a pitcher this young touches 100 mph. With that in mind, Baseball America has compiled every officially-known 100 mph high school fastball, resulting in a list of 17 players to accomplish the feat:
| class | player | state | max velo |
|---|---|---|---|
| 2014 | Tyler Kolek | Texas | 102 |
| 2016 | Riley Pint | Kansas | 102 |
| 2017 | Hunter Greene | California | 102 |
| 2021 | Chase Petty | New Jersey | 102 |
| 2025 | Jack Bauer | Illinois | 102 |
| 2001 | Colt Griffin | Texas | 101 |
| 2011 | Archie Bradley | Oklahoma | 101 |
| 2021 | Roki Sasaki | Japan | 101 |
| 2023 | Travis Sykora | Texas | 101 |
| 2011 | Dylan Bundy | Oklahoma | 100 |
| 2012 | Shohei Ohtani | Japan | 100 |
| 2019 | Daniel Espino | Georgia | 100 |
| 2021 | Chase Burns | Tennessee | 100 |
| 2022 | Brock Porter | Michigan | 100 |
| 2022 | Nazier Mule | New Jersey | 100 |
| 2025 | Seth Hernandez | California | 100 |
| 2025 | Miguel Sime Jr. | New York | 100 |
Back in 2001, Texas high school righty Colt Griffin made history when he became the first high school pitcher to be clocked at 100 mph. Viewed as a first baseman and outfielder during the summer of 2000, he threw in the low 90s in a few sporadic outings. After a slot change, he came out in the spring and touched 100 mph, with a few reports of 101.
Griffin was ahead of his time. It took 10 more years for the next high school pitcher to join him. In 2011 two pitchers from Oklahoma did it in the same draft class: righthanders Dylan Bundy and Archie Bradley.
Beginning with the 2010s, it has been more common to see high school pitchers reaching the 100 mph threshold. In fact, since 2011, we haven’t gone back-to-back years without a new high school pitcher adding his name to the list.
The 2025 trio of Hernandez, Bauer and Sime Jr. is the first three-player mix of triple-digit fastball throwers in the same draft class. However, 2021 high school grads Chase Burns, Chase Petty and Japanese superstar Roki Sasaki all reached 100 mph or better in the same graduation year, even if they weren’t all eligible for the draft together.
It’s certainly possible—and perhaps even likely—that the velocity king himself, Aroldis Chapman, touched 100 mph during his high school age years, though we don’t have official numbers to back that up and say for a certainty.
