Can you define power pitcher and a pitcher that is a spinner?
Power pitchers are characterized by higher than average velocity in college working in the upper 60' to low 70's. May or may not mix speeds very well, and some are what has been termed "effectively wild". These are usually your strikeout pitchers. - In baseball terms think of Nolan Ryan or Randy Johnson
Spinners typically will work in high 50's to mid 60's, usually have a high spin rate, and very good command, and mix speeds very well. They are quite adept at making hitters look like total fools. In baseball terms think of Greg Maddux who dominated MLB with mid 80's heat.
