"he told me to 'crank' the wrist more to the right side (for right handed pitchers) to get the ball face sideway more in the landing position."
What did he mean? Were you throwing a curve? Your statement isn't very clear. To "crank" the wrist right says to me that he wants you to supinate and that isn't a good thing, so you may have misunderstood what he was trying to tell you. What are you going to him for?
