These are the Top 150 high school prospects for the 2027 MLB Draft. The Over-Slot team set off to attend as many premier events as we can this summer. Hoover, Alabama... Cary, North Carolina... Long Beach, California. We have personally seen 142 of the 150 players with reports on this ranking.

As always, the Over-Slot boards are built on three steadfast pillars:

- Live Looks

- Data and player-metric evaluations

- Discussion with scouts in the field

Speaking of data... Summer data, high school athletic testing, showcase tournament performances, and more. We've included all of it from the summer prior. Furthermore, we're nose-deep into the numbers from the summer thus far. This update of the Over-Slot Top 150 High School Board brings more information and metrics into the fold than ever before. While we're still a ways away from fully understanding what the 2027 Draft will look like, each new piece of information helps provide signal toward a consensus.

Shortstop Dylan Seward is still our top high school prospect at this stage, however there are a few names nipping at his heels. An 80-grade runner with impactful skills from both sides of the plate, Seward can impact the game. He's as exciting as it gets. Southpaw Connor Salerno is our top-ranked pitching prospect with his 97 mph heater and polished, firm secondaries. 

Enjoy.
