I asked Dave Cameron in the chat today
Would it be possible to create a system that uses velocity as well as pitch f/x movement numbers to rate pitches? We could use it to compare pitchers start or pitches across starts...eta
He said that has already been done. But where? and what is it called?
For example Matt Moore has 9.2 inches of horizontal movement 11.1 inches of vertical movement and a pretty velocity of 94.2. So we can see his fastball is better than say Jason Hammel. But can we give them both a number in terms of stuff from that data?
