Should the Marlins select Miller if he’s available with their first-round draft pick?

Position: 3B 

Height: 6’2″

Weight: 205 pounds

School: J. W. Mitchell HS (FL)

Commitment: Arkansas

Aidan Miller is a 6’2”, 205-pound infielder out of the talent-rich Central Florida region. Miller is one of the highest-ranked prospects in the 2023 MLB Draft class. On MLB Pipeline, Miller is the 12th-ranked prospect and the #1 ranked third baseman in the draft class.

Miller is the fifth-ranked high school prospect in the 2023 MLB Draft class. On Perfect Game, Miller is the sixth-ranked prospect and the second-ranked shortstop in the country. He’s also the second-ranked prospect in the state of Florida. 

Miller is one of the best pure hitters in this draft class. The Sunshine State native is a big-time power threat who has shown off that power against great competition. He’s also a very good defensive player who originally played shortstop until he filled out his frame. 

Due to a hamate injury, Miller barely played during his senior season.


  • Raw power potential
  • Good hitting tools
  • Hits well against elite velocity
  • Plus fielding skills
  • Excellent arm strength 
  • Lots of offensive upside


  • Average speed
  • Doesn’t have much more room to fill in his frame

Pro Comparison: Evan Longoria

Projection: Top 20 pick

Bottom Line

The Miami Marlins used their first-round draft pick last year on third baseman Jacob Berry. The former LSU Tiger was one of the best hitters in college baseball during the prior two seasons, but he has not hit well in the Marlins organization and he’s already moving down the defensive spectrum (splitting reps between 3B and 1B). Due to these offensive and defensive woes, the Marlins might need to find another third baseman in case Berry doesn’t figure it out.

Aidan Miller is a talented hitter with plus power and arm strength. He would be an excellent pick for the Marlins, though Miller should demand a hefty signing bonus to forgo his college career.
