Includes Teheran (11th) and Vizcaino (19th). Delgado gets mentioned at the bottom. And if you are wondering, Teheran is ranked behind Martin Perez, Aroldis Chapman, Jeremy Hellickson, and Casey Kelly among pitchers. So, as good as he is, he isn't the greatest pitching prospect in baseball...yet.
UPDATE: This is insider only, sorry that I didn't mention that before if you weren't able to get to the link. Selected quotes below.
11. Julio Teheran, RHP, Atlanta. A big fastball, a plus change and an improved breaking ball have helped him dominate at two levels this year -- and it's not just being in pitcher-friendly Myrtle Beach. Six of the nine Colombians to reach the big leagues came from Cartagena -- as does Teheran. I'm still waiting for our first prospect from Macondo. Previous ranking: No. 63
19. Arodys Vizcaino, RHP, Atlanta. He's producing outstanding numbers so far with a plus fastball/above-average curve and a very low-effort delivery. Previous ranking: No. 43
and under the "Why Not Section"
Randall Delgado? Total package doesn't have the big upside of Teheran, and he's not as polished as Vizcaino
