perspective. He is the creator of the sabermetric measure of "Pitcher Abuse Points." The term Pitcher Abuse Points – PAP – was coined by Jazayerli in an article published on the Baseball Prospectus (BP) website in 1998, and the statistic was regularly reported and discussed on the website. In 2001, Keith Woolner came up with an alternative measure, termed PAP³, which has served as the basic pitcher use statistic reported on the BP website since then. For a summary, see Keith Woolner, "Doctoring the Numbers: PAP³ FAQ," BaseballProspectus.com (June 6, 2002). Jazayerli has published seminal research on the relative merits of the 4-man and 5-man pitching rotation.
