I don't know much about Martinez, but I'm not a big fan of any of those guys outside of Maybin, Upton, and McCutcheon. Young is a year and a half older than Felix, and while he has shown a pretty good batting eye and more power, he will strike out a bunch and won't have much of an average to show for it. He seems to me to be a RH version of Steve Finley, without the big years around age 36-38. The only thing Kemp has shown more than Felix is power, which makes sense for someone 2 inches and about 30-40lbs larger. High A- Pie .301, .364, .448; 415 ABs, 39 BB, 113 K Kemp .306, .349, .554; 418 ABs, 25 BB, 92 K Much more power shown by Kemp, but keep in mind he was 20 in low A, while Pie was 19. Both are young for the league, but Felix was more raw and somewhat made up the power difference with BB ratio. AA- Pie .304, .349, .554; 240 ABs, 16 BB, 53 K Kemp .327, .399, .528; 199 ABs, 20 BB, 38 K Pretty decent advantage for Kemp there, but Pie showed he can possibly keep up with him in power in the long-run. Kemp made a splash in the majors for a while, but had 8 BBs to 41 Ks in 122 ABs, showing he's still a free swinger. While I can't completely disagree with the rankings, I think Felix could easily be the 3rd best ML'er on that list. Maybin looks like the real deal, but the other young guys are so raw and a long way away.
