Cause and effect may be impossible to prove, but... in 2003, your leaders in Pitcher Abuse Points (BP's metric on high pitch counts): 1) Javier Vasquez, 2) Kerry Wood, age 26 3) Livan Hernandez 4) Mark Prior, age 23 Who in the entire league threw the highest average number of pitches per game in 2003? 1) Mark Prior [113.4] 2) Kerry Wood [110.7] And Vasquez suffered through two seasons well below his career-norm performance level, as well. Only a pitching freak like Livan Hernandez can take that kind of workload without suffering from drops in performance or injuries afterwards. I would really be interested to see how these numbers project in past years. I am much too lazy to do it myself though.
