What are the Physics Behind Baseball Pitching Techniques and Illegal Pitches?

[nike45]

I am doing a research paper on many of the different kinds of pitches in baseball like fastball, curveball, knuckleball. I wanted to do something on illegal pitches like a spit ball, scuffball, or somehting like that but can't find much infomation. Can anyone help? thanks

A prime reference on the physics of baseball should be Robert Adair's book "Physics of Baseball", available for about $12.00 at Amazon.com:

Robert Adair is a Professor Emeritus of Physics at Yale.
