Fangraphs has Vlad as the #1 prospect in 2019 (Ohtani 1 and Acuna 2 last year) and gave him a 70 FV rating. That’s what they had Ohtani at last year.
They also have him an 80/80 Raw Power grade, which is insane. They have him at 65/70 Game Power, which is also pretty insane.
They think it’s only a matter of time before he has to move off of 3B though.
