Agree with the selling out for power bit, so I don't think he has nearly the speed or defense of Stubbs, but much more so of Yorman. As I've said since Day 1 (ie yesterday ) I think his best comp could be to another OF that was also drafted in the 2nd round out of Puerto Rico, Carlos Beltran.
(I'm thinking more the 30+ HR 20 SB, average defensive New York Met Carlos Beltran rather than the 40+ SB plus-plus defense Kansas City Royal Carlos Beltran.)
The kid's got a ton of physical development left to go. His power could eclipse Beltran's, best case. His speed could become average, who knows. Generally speaking, I have to think the experienced scouts' well-trained eyes make the Juan Encarnacion comp a realistic one.
