Top 2025 MLB Draft Prospects to Eye Out of Poly Prep and Don Bosco Prep High Schools


The new top 100 MLB Pipelines’ Draft prospects list for the 2025 rankings recently came out with Ethan Holliday, the son of Matt, a former outfielder who played 15 MLB seasons, topping the list.

Additionally, that list includes two players from Brooklyn’s Poly Prep Day Country High School: Right-handed pitcher Justice de Jong at 96 and another righty hurler in Miguel Sime at 100.

Right now, the 6-foot-3, 210-pound de Jong, a Duke commit, has legitimate two-way potential. But after a productive summer on the bump on the baseball circuit against top talent, scouts project him as a pitcher for his future.

As for Sime, he has shown he can reach 98-99 MPH and is working on developing breaking stuff, with a hard slider that goes off at 78-81 mph and nice spin to it.

Scouts believe he will need to control his power stuff in order to be successful at the next level and beyond.

The 6-foot-4, 235 Sime is committed to Louisiana State if he forgoes the 2025 MLB Draft.

Another player to keep an eye on is shortstop/second baseman Nick Becker, a player out of New Jersey’s Don Bosco Prep, who checks in at the 56th spot.

The Thiells, New York, native already owns good bat-to-ball skills and is a solid defender with good speed. At 6-foot-3, 180 pounds, all of his physical tools should develop even more as the Virginia commit matures, per baseball scouts projections.

But Becker may not enter the draft and follow his brother Eric, who is a sophomore at Virginia, into the same college.

With baseball in his blood — the Beckers’ dad Jeff, a former Duke player who spent two summers in the Cleveland Guardians Minor League system — Nick has the chance to be the best player in the family, according to scouts.
