Here is an overview of the top high school and college players that the Miami Marlins should consider drafting this summer. Some prospect evaluations have changed since the prior MLB Draft big board was released on college baseball's opening day. There have also been 50 new players added to the board.

The Marlins will make their first selection at No. 7 overall, then pick again at No. 43, No. 46, No. 79, No. 109 and No. 140. They have the third pick in all subsequent rounds (No. 168, No. 198, No. 228, etc.).

The table below includes each prospect's age as of July 13, 2025, their school, position(s), handedness, measurables and overall future value on a 20-80 scale. Click the hyperlinks for full-length Fish On First prospect profiles.

Risers

Riley Quick (previously ranked 79th, now ranked 11th) had Tommy John surgery in 2024. He has bounced back with a great season, posting a 3.54 ERA with 9.1 K/9, 3.3 BB/9, and 0.7 HR/9. Quick is now the second-ranked college starter on the board.

The Alabama native touches 99 mph with ease with his sinker. His elite slider gets whiffs out the zone and his changeup has become a good third option.

Joseph "JoJo" Parker (previously 82nd, now 14th) has also skyrocketed up our big board and many others around the draft community. The Mississippi State commit has excelled in recent months while the high school draft circuit heats up.

Parker plays a smooth shortstop with an advanced swing for his age. He has a high rate of contact and has posted very good exit velocities. He's poised to be a first-round pick.

JoJo's twin brother Jacob Parker (ranked 129th) is also projected to be selected during the first three round picks of the draft.

Other prospects who have risen at least 30 spots since February include Alex Lodise (69th to 30th), Ethan Petry (61st to 24th), Angel Laya (unranked to 44th), Cooper Flemming (unranked to 57th) and Cody Bowker (unranked to 67th).
