College Commitment: Vanderbilt

Seth Hernandez has a real shot at being the first overall pick on July 13th in Atlanta. If he comes off the board within the top ten, which seems to be inevitable at this point barring injury, Hernandez would be just the fourth high school arm drafted within the top ten since 2020. His team - Corona High School - is a school you’ll likely hear a lot over the next couple of months as it also features two of the top high school hitting prospects, Billy Carlson and Brady Ebel.

Hernandez is a 6’4” 190 pound right handed pitcher committed to Vanderbilt, and is ranked as the fifth overall draft prospect by MLB Pipeline. He came in to the 2025 season as the clear-cut top high school arm in the draft large in part due to a big summer last year on the showcase circuit. Hernandez is a very projectable starter because of his physical attributes and pitch mix. He features a very smooth, repeatable delivery with long levers that create great extension.

It’s roughly a four-pitch mix, but his fastball and changeup is his bread and butter. A changeup as the main secondary is rare for a high school arm which speaks to Hernandez’s pitch-ability. He has ran his fastball up as high as 100 mph but sits anywhere from 95-98 mph. It has a lot of juice and he may even be able to add a tick on it as he’s expected to fill out his 6’4” frame further. He is regarded as having great feel for his changeup and it may be his best offering in the long-term considering how good it is now. The curveball is his main breaking ball and is a super high spin, traditional 12-6. He recently started using the slider and it’s development will be a huge addition to the arsenal if he can really fine tune it.
