I meant in what way would Castro be Sanchez all over again. Did he mean the starter vs. reliever debate or some other similarity he saw. The Castro has thrown strikes statement was just meant to say they aren't similar in that regard.
That slider looked pretty nasty from Castro.
There have been mixed reports on his off-speed pitches. Some say his slider is weak and change is potential plus, others have said great slider weak change. It looked pretty good there.
