Miami Marlins AAA
2026 Fantasy Outlook
As the Marlins continue to accumulate young outfield talent, Alderman's path to an early 2026 MLB debut is becoming less clear. However, he had an impressive and under-the-radar run at Triple-A to close 2025 that makes him a nice flyer in dynasty and draft-and-hold leagues. Alderman, who made a name for himself with his exit velocities at the 2023 draft combine, may have just been beating up on worn down late-season pitching at Triple-A, but he managed a .303 average, seven home runs, two steals and a 160 wRC+ in 20 games. His .333 BABIP and 26.8 percent strikeout rate don't sound any alarms, given the amount of damage he can do. Prior to getting to Triple-A, Alderman hammered 15 homers with 20 steals and a 130 wRC+ in 110 games at Double-A. He cut his groundball rate from 54.2 percent at Double-A to 36.4 percent at Triple-A to unlock the power breakout. Alderman is an average defender in right field, thanks to a plus arm and solid speed for a player his size. While the Marlins have four or five power-first corner outfielders on the roster, Alderman fits right in with that group and has the talent to emerge with a regular role by season's end.

Finding form after return
OFMiami Marlins  AAA
July 4, 2026
Alderman sports a .286/.375/.486 slash line over his last 10 games for Triple-A Jacksonville with two home runs, one steal, eight runs and eight RBI.
Analysis
The 23-year-old outfield prospect missed about a month of action after suffering a wrist injury in mid-May, but Alderman returned to the lineup for the Jumbo Shrimp on June 16. After striking out eight times in 13 plate appearances during his first three games back, he's quickly regained his form. Alderman has mainly played right field this season while seeing some action in left field and at first base as well, and a big-league debut in the second half remains possible if he keeps his strikeouts in check.
