Per Fangraphs Jan 2021:
Duran - 7th ranked Sox prospect, 55, 45, 35, 70, 40, 50
The Red Sox and Duran added yet another wrinkle to his already surprising pro development track by making a very significant swing alteration that was evident during the club’s alternate site activity. He now starts with a narrower base than before, and his hands are set much lower to start, changes that theoretically create better rotation up through the kinetic chain and natural swing loft, respectively. We won’t know if the changes have a substantive impact on Duran’s power output until sometime in 2021, as his alt site hitting metrics are meaningless because they were generated against the same mediocre pitchers he saw over and over, but visually, it now appears Duran can better lift pitches in the bottom of the zone. He didn’t exactly hit for power in Puerto Rico over the winter, though, and the org thinks it’s because his new swing requires more precise timing, which Duran hasn’t yet found.
Still, let’s not forget Duran’s tools (he’s a 70 runner) nor the foundation of statistical performance he has laid dating back to college.
Wilson - 42nd ranked prospect, 35, 45, 55, 60, 50, 35 (lower hit tool, more raw power than Duran)
Wilson has some carrying tools. He has grown into power, his swing creates natural lift, which enables it to play in games, and he has plus straightline speed. His feel for contact is very limited, so he exists in that Keon Broxton zone, where clear big league tools often get squeezed off rosters by someone with similar skills who hits left-handed, or boasts some other marginal improvement.
