 So, you know, this is a pitch the batters are recognizing as a fastball, and then all of a sudden as it's about to cross the plate, it just drops and tumbles on them. So you throw in the sweeper and the slider and a changeup and a curveball. I mean, this is a guy with a five- or six-pitch mix that he can use, and he uses primarily four. But it's a devastating talent, and it's a guy who is a student of the game and is studying how to use these pitches, how to make them more effective, and how to get better with every single start.
