#5      Seth Hernandez

           RHP   Corona (CA)

18/years old

6' 4"       190

COMMITTED - Vanderbilt

Scouting grades: Fastball: 65 | Curveball: 55 | Slider: 50 | Changeup: 60 | Control: 50 | Overall: 60

On the radar for quite some time, Hernandez started making it clear as a junior, when he won National High School Invitational MVP honors after tossing a complete-game shutout to help his Corona High School team win the tournament, that he’d be the top high school arm in the Class of 2025. He cemented it by showing elite stuff at summer showcase events like USA Baseball’s 18U National Training Camp and the Area Code Games.

Hernandez has an ideal projectable 6-foot-4 pitcher’s frame with the athleticism teams love to see from young power arms. Always on time with an online and loose delivery, Hernandez has big stuff and a feel for all four of his pitches. While he touched triple digits at the Area Code Games, he typically sits in the mid-90s, touching 97-98 mph. His best secondary offering is his changeup, and it’s plus right now, thrown with a lot of confidence and missing bats with it thanks to its good action and how it plays off of his fastball plane well. His curve, a true 12-to-6 spike curveball, has the chance to be plus with hard, tight and late action to it, sometimes registering RPMs in the 3,000 range. He started featuring a harder slider more on the showcase circuit.

In addition to his pure stuff, Hernandez does a solid job finding the zone, especially considering his age and power stuff. Committed to Vanderbilt, he gets very high marks for his work ethic, showing the ability to make adjustments and corrections to put himself in position to be one of the first pitchers taken in the 2025 Draft.

5. St. Louis Cardinals: Seth Hernandez, RHP, Corona HS

The St. Louis Cardinals are likely headed for a bit of a rebuild under Chaim Bloom and the fifth pick in the 2025 MLB Draft is a great place to start. Seth Hernandez, a 6-foot-4 righty, already offers the frame and athleticism clubs like in a prototypical pitcher. Hernandez’s makeup has reportedly drawn very high marks, per MLB.com, a characteristic that incentivizes a club to take a chance on a projectable high school pitcher. Hernandez is also enticing because of a four-pitch mix – fastball (97-98 MPH max velocity), curveball (projects to be above-average), changeup (second-best pitch) and a slider – that would provide the Cardinals organization with plenty to work from.

2. Seth Hernandez, RHP, Corona (California)

Hernandez touts a long, 6-foot-4 inch frame that helps him get up to 98 mph on the radar gun. He also touts a heavy change-up that is advanced for his age. He’s likely to be the first pitcher taken.

4. Colorado Rockies: Seth Hernandez, RHP, Corona (California)

Some feel Hernandez is the best pitcher in the draft with a 98 mph fastball, while measuring 6-foot-4 and 190 pounds.

He is the best pitcher in his high school class, and he’s committed to Vanderbilt.

The Rockies taking him here is based on the team taking long-term upside, instead of taking a player who could debut as early as 2026.

The Rockies were one of the worst teams in baseball in 2024 and have one of the better farm systems in the game at the moment, according to MLB pipeline and Baseball America.

6. Pittsburgh Pirates: RHP Seth Hernandez, Corona HS (CA)

One of three Corona High School players who could wind up hearing his name called in the first round, Hernandez enters the spring as the top prep arm in the country. With an extremely projectable 6'4", 190-pound frame and electric present stuff that includes a fastball that has touched 98 mph and a plus changeup, the Vanderbilt commit checks all the boxes to be a future ace.

4. Seth Hernandez – RHP

HT/WT: 6’4/195 | Bat/Throw: R/R | School: Corona (CA) | Commitment: Vanderbilt | Age: 19

At this stage of the 2025 cycle, there’s no better arm in the class than Hernandez.

At 6’4, 195 pounds, Hernandez has plenty of projection remaining to his frame and his operation is as easy as they come. He’s very athletic and moves fluidly down the mound with loud arm speed and a methodical nature to his timing.

His fastball has sat in the low-to-mid 90s thus far, though he’s gotten up to 96-98 MPH, even touching triple digits in shorter stints, and projects to sit closer to that mark as he fills out his frame.

He gets a solid extension and fills up the strike zone, as well as showing a tendency to miss bats on the top rail. His change-up is one of the best in the country, a low-80s parachute that flashes plus with a ton of sinking action and velocity separation from the heater.

He’ll mix in a bigger curveball in the upper-70s and a firmer cutter/slider hybrid in the mid-to-upper-80s, both of which possess spin rates near 2,700 RPMs. His secondary command will need refinement, but overall, he peppers the strike zone.

The mix of pure stuff, projection, and athleticism make him the best arm in a prep class that lacks dynamic arms. Hernandez is on the older side of the class and will be 19 on draft day. If he gets to campus, he’d be eligible as a sophomore at Vanderbilt.

8.  Seth Hernandez, RHP, Corona (Calif.) HS

A two-way guy coming into this spring, as someone who also offers plus raw power with the bat, but he is a higher-ceiling pitching prospect because of the projection to his frame as a starter with a fastball that can get into the upper 90s mixed with a hard breaking ball that has swing and miss potential.

8. Toronto Blue Jays: Seth Hernandez, RHP, Corona HS (CA)

Hernandez could go much higher than this. He’ll have the earned skepticism of being a prep right hander but he might be the best pitcher in the draft class. The 6-4, 190 pounder has the profile of a top of the rotation starter. He was stellar on the summer circuit and he’s an athletic, power arm with premium stuff.

7. Marlins: Seth Hernandez, RHP, Corona (Calif.) HS (No. 5)

Hernandez is interesting as a right fielder with well-above-average raw power and arm strength -- and more interesting as a projectable righty who can reach 98 mph with his fastball and spin a wipeout curveball.

9. Cincinnati Reds

Seth Hernandez, RHP — Corona HS

HOMETOWN: Chino, California

HEIGHT: 6-4

WEIGHT: 195

BAT/THROW: R-R

Hernandez might not even be available this late in the Draft but they would welcome another pitching prospect as they’ve found more and more success in developing that profile of late.

The thing that immediately stands out about Hernandez at this stage is his mature pitch-ability and his natural talent to pound the strike zone. He’ll work in the low 90s, grabbing 96 with solid spin and carry through the zone. His best weapon currently is a low-80s slider with solid depth and some sweep, as well as an upper-70s changeup, killing spin well.

Hernandez has a track record against older bats and he’s shredded them up. When you consider the resume, the frame, the projection, and the present feel for the mound, there’s upside here for an impact righty at the next level.

 

8/11/24 - Sports Gambling Podcast - 2025 Mock Draft

Seth Hernandez, an Elite Charter Academy product and Vanderbilt commit, is a very projectable 6-4, 190 pounds RHP. He lands closed and finishes with long and whippy arm action. Hernandez’s fastball sits in the low 90s with good ride. Hernandez has two plus offspeed offerings (changeup and slider).

 

link  - RHP Seth Hernandez - Corona (CA)

Budgeoning stuff. That’s the name of the game for Seth Hernandez. He’s eclipsed himself as the number one arm in the country, and it is easy to see why. Tyler caught him at USA 18u just recently, and the fastball was 96-98 mph with tons of carry. It was a shorter stint, and he usually is in his low to mid-90s. That’s fantastic for a prep arm with much room to grow and a very buttery operation. He pairs that fastball with a slider and a changeup. The slider has spin rates above 2,700 RPMs, and Tyler saw it with a ton of velocity that was 85-98 mph, giving it the action of a cutter. His changeup is even filthier and creates great deception off his fastball. It drops out of zone and has a ton of depth to it. As of now, Hernandez is committed to Vanderbilt, but he expects to be one of the first arms off the board. It seems highly unlikely that he will make his way to campus.

 

 Tyler Jennings   @TylerJennings24

Seth Hernandez, the #1 arm in the country for a reason.

Hernandez's FB was electric, sitting 94-97 T98 with strikes and carry upstairs. Flashed a tight SL at 85-89 with cutter-esque shape and a sharp fading CH at 80.

That was loud.

2024 National Showcase

Seth Hernandez is a 2025 RHP/1B/3B with a 6-4 195 lb. frame from Chino, CA who attends Corona. Extra-large, athletic frame with broad shoulders and long limbs, lots of twitch and physical projection remaining. Ran a 6.75 60-yard dash. Primary right-handed pitcher, didn't throw in this look but consistently into the mid-90s with top of the class arsenal. Smooth actions on the approach to the ball in the outfield, clean medium length arm stroke in back with quickness to release, lots of arm strength and carry to the intended base with low effort, works through the ball well. Right-handed hitter, begins with a wide base and shows rhythm throughout, easy hand speed through the zone and able to impact the ball with authority to the pull side. Consistently on the barrel with a solid launch and plenty of leverage through the point of contact. Highest level tools across the board. Excellent student. Verbal commitment to Vanderbilt. Selected to play in the Perfect Game All-American Classic.

5. Seth Hernandez, RHP, Corona (CA) HS (Vanderbilt commit)

Hernandez, a Vanderbilt commit, looks to be the top prep arm in this draft class. Standing at 6’4, he has a big frame that allows him to reach the upper 90s with his fastball on a consistent basis.

With a couple of strong offspeed pitches to go along with his fastball, Hernandez projects well as you look into his future. It would be easy to see a MLB team fall in love with him, and him end up as a top pick.
