Pedro Hernandez has a great change-up. He got outrighted today, meaning no other team claimed him on waivers. Why? Because he has a below-average fastball. What made Johan so spectacular was the 94-mph fastball with sink, combined with the 78-mph change-up. Also, he had three major-league pitches. When the blister made the slider impossible, he became ordinary. When he had all three going, he dominated. I know Sulburan throws harder than Hernandez. But he needs to have a three-pitch mix to be mentioned in the same discussion with Santana. And he needs to add a foot or movement or both to his fastball as well. He's young, so there's some hope. But if he had those things, he would be a top 10 prospect.
