Some
specifics
Fastball -- A four-seamer that is straight, a two-seamer that tails because he holds it like a screwball, and a cutter.
Slider -- A standard one with short break, a slower version that "bends more" and one that's "between a slurve and a cutter."
Changeup -- One from his standard delivery, another almost sidearm.
Really good read, and trying to wrap your mind around Sonnanstine only walking 101 in over 600(fixed... silly RJ) pro innings is a hard thing to do.
