Roids wore off. NO! How dare you. The guy who told him how to hit homers, who only the he saw, was named George Baruth (omg, George "Babe" Ruth?!?!) and he left town at the end of the book. That's when he stopped hitting homers. Hahaha, I remember that part. Then he wrote the sequel where Eddie Cicotte of the Black Sox shows up and teaches him how to be a jackass.
