While I did present this type of analysis at the 2009 PITCHf/x summit, the most definitive publicly available work on the subject was done by Mike Fast in a pair of articles published in BPro, just before he was stolen away by the Astros: http://www.baseballprospectus.com/article.php?articleid=15532 http://www.baseballprospectus.com/article.php?articleid=15562 Also, as noted somewhere upthread, I gave a talk on this subject at the 2013 Saberseminar: http://baseball.physics.illinois.edu/Saberseminar2013-v2.pptx.
