Roman Anthony began this season as the number one hitting prospect in the game according to Baseball Prospectus. Nothing guarantees success at the MLB Level, but the list of players who have recently held that title is, uhh, really, really impressive.
With the exception of Jackson Holliday — who, after a difficult rookie campaign last year, now has a 124 OPS+ — each of the last ten players who was named the top hitting prospect by BP has subsequently made an All-Star team. In fact, every single player on that list except for Holliday and Wander Franco has received MVP votes (Holliday is still adjusting to the game, while Wander Franco never adjusted to the human condition).
