Top 10 high school players available on Day 3 of the 2023 MLB Draft

July 11, 2023

Day 3 of the 2023 MLB Draft will see Rounds 11 through 20 take place at T-Mobile Park. There are still a healthy dose of high school standouts available for teams to pick early on Tuesday afternoon.

It should be noted, college players before far more likely to be drafted at this stage in the draft as bonus pools get smaller and high school players are far more likely to turn down smaller dollar figures in favor of going to college.

That said, some teams maneuvered their day one & two selections to allow themselves some flexibility in spending into the later rounds. Some of these players’ bonus demands simply will not be able to be met and they will go to college. Some, however, are still listening to offers. This is when it gets fun.

Peterson sits 91-94 mph, touching 95, with running life late, filling up the zone. Slider features high spin, resting 78-81 with late break and he’s has shown the ability to manipulate shape. The breaking ball here is the real gem. He flashes a changeup at 83 with tumble and a mid-70’s bender as tertiary offerings. It’s an athletic, compact delivery with definitive starter traits.

In a very deep prep shortstop class, Cholowsky stands out as having some of the highest projectability with supremely impressive talent on the defensive end. It’s a long, athletic frame with tons of room for growth  with high-level actions in the dirt.

He has great range moving laterally and has the arm strength to make every throw. Hands stand out with both the glove and with the bat. Extremely hitterish in the box with advanced barrel control and ability to use the entire field.

Chowlosky posesses a high-level profile that should only continue to get better. Scouts only question his future impact at the plate, but he has a lot of growing ahead of him. He’s is expected to be a tricky sign considering his opportunity to play both football and baseball at UCLA.

Let’s start with maybe the most important piece of Volchko’s profile: he’s committed to Stanford. That’s going to be an awfully difficult poach unless the money is big. It’s certainly a prototype 6-foot-4, 215-pound frame with a fastball that really explodes.

Volchko generates plenty of carry on the heat, missing bats aplenty at the top of the zone. He’s got two breaking balls, a low-to-mid 80s slider being the more consistent two-plane weapon. He’s shown good conviction and bite on a traditional bender, too.

There’s a bit more growing to do, and the operation will tighten up as he gets older, but the arm is loose and the whole arsenal works well. He’s got some scouts turning him in with 7-figure valuations, so we’ll see if he can be pulled from Palo Alto.

Caraway has a ton of strength in his hands that allow him to manipulate the barrel to all fields depending on whether or not he’s out in front of spin/velocity. A violent hitter with power to all fields, Caraway is an offensive threat to do damage.

Caraway has a good throwing arm and can run a bit too, though his size likely sets him up for a future in a corner. Scouts would like to see him lock into a firmer front side to handle bigger velocity as he climbs the ladder to ensure the hit tool buoys at healthy levels.

Johnson is a big, physical lefty up to 97 mph with plenty of arm-side run and sink coming out of a deceptive, low slot. He’s begun spinning a better breaking ball of late, a weapon against both-handed hitters. Scouts are split on whether he’ll be able to start at the next level, but this is an out-getter with a big, strong, projection frame. Johnson could throw pretty hard as he continues to mature.

Standing at the top of a very good North Carolina State 2023 recruiting class is the imposing, high-waisted 6-foot-5-inch frame of Mako. An abundance of projection sounds out with this profile led by an above-average fastball/slider combo. The fastball will live in the low-90s with explosive life at the top of the zone and plenty more velocity to project. The slider could be a plus pitch already in the high-70s with consistent shape and an innate feel to spin (RPMs north of 2800).

Mako will absolutely fill the zone up with both pitches while missing plenty of bats. His changeup remains a work in progress, but it’s hard not to be bullish on the upside.

Holcomb is a big, athletic shortstop with massive power, reminiscent of Brady House from the 2021 class. Holcomb boasts big-time bat speed and raw power that finds its way into games already.

His solid defensive actions and near top-scale arm strength will keep him on the left side infield for the long-term. Scouts want to see a consistent approach at the plate and less swing-and-miss as he continues to develop, showcasing his talents as a hitter first and foremost.

An Alabama commit, Adams is considered one of the more promising left-handed pitching prospects in the class with immense projection and present stuff. The velocity has really ticked up over the last 12 months, now brushing 95 mph, sitting comfortably in the low-90s deep into his outings.

Adams has a promising upper-70s breaking ball that he commands well with big shape and projection thanks to its current velocity and Adams’ arm speed. He’ll mix in a changeup as well, though it’s presently tertiary and it used seldomly against RHH.

Gray is an impressive athlete with a long, physical frame and a short, compact path to the ball. He’s got a ton of projection, and is rather green having not played much baseball due to football commitments. He’s a two-sport standout with a future at wide receiver at UCLA, though scouts think he’s signable away from that commitment.

There’s been some comparisons to George Springer when he was a prepster coming out of Connecticut. Gray is tooled up with potential polish and impact in his not-too-distant future. He is an above average runner and takes solid, long-gaited strides to the spot in the outfield.

The younger brother of Angels first rounder Reid, Parker Detmers is another broad-bodied righty with a budding fastball up to 93 mph and a breaking ball that shows promise. Detmers has a short-arm release that presents some natural deception.
