Here we go.
Before we get started here, please keep in mind that that the prospect list you’ll find below skews toward each player’s long-term fantasy potential. There are several prospects who would rank higher on a “real life” lists, but these are the top prospects who you’ll want to watch closely in fantasy baseball leagues.
Where’s Roki Sasaki?
Fresh off signing with the Dodgers, Sasaki qualifies as a prospect and will be ranked as one of — if not the — top names on many lists. Because of his experience in NPB, I believe it’s a mistake to treat him as a prospect. If he were to “qualify” for my list, he’d likely rank in the top three, and certainly would be the top pitcher among the group. Those who want to treat him like a prospect are welcome to because of his rookie eligibility, but it just doesn’t feel like the right decision, for me.

*Age=Reflects the age the player will turn during the 2025 season
1. Dylan Crews, OF, Washington Nationals
Age: 23 | ETA: Debuted in 2024
Crews was the second pick of the 2023 draft behind fellow LSU product Paul Skenes, and while he didn’t make quite the impact that the 2024 Rookie of the Year did, he was able to reach the majors a year after being selected and showed off his enormous upside over 31 games. A right-handed hitter, Crews has plus power and speed at his disposal; the type you see in players who hit 30 homers and steal a similar — if not more — bases on a routine basis. On top of that, the 5-foot-11 outfielder has a competent approach at the plate and a swing path that should allow him to be a solid contributor in the average category as well. Crews is going to be an everyday player for the Nationals to begin the 2025 season barring something unforeseen, and he’s capable of contributing in every fantasy category at the highest level.
2. Roman Anthony, OF, Boston Red Sox
Age: 21 | ETA: 2025
The Red Sox made Anthony the 79th pick of the 2022 MLB Draft, and while he was considered one of the best prep bats of his class, the 20-year-old’s stock has risen considerably, with many believing he’s the best hitting prospect in the sport. He hit .291/.396/.498 in 119 games last year while reaching Triple-A, and he forged a .982 OPS in 35 games once he reached Triple-A. Anthony has plus power in his left-handed bat, and his hit tool isn’t far behind with a smooth stroke and an ability to make hard contact to all parts…
