if you buy that he was the type of genetic freak that could just sling 90-95 2.5 days a week while mostly everyone else was probably low 80s, combined with how much weird movement you’d get from using the same ball all game…i could see it being true

He threw mostly fastballs, but definitely threw occasional curveballs.

He did have a curveball and a changeup that were considered subpar, so the Senators encouraged him to throw his fastball almost exclusively.
