Pitcher Aging Patterns: Determining Changes in Baseball Over the Years
Chris Jaffe
King I
This research is based on an excel database he created that contains year-by-year win shares information sorted by pitchers’ age for every pitcher who had at least 100 starts from 1876-2004, and whose birth year is known. In total there are almost 1200 of these pitchers. Most questions are looked at by examining pitchers grouped together by decade of birth. From there one can try to answer some questions: Have pitchers in any period in baseball aged better or worse than another period? If so why might that be the case? Are modern pitchers aging better or worse? Do pitchers who tend to make their mark earlier do better throughout their career than others? Do lefties and righties age the same or not? What sort of pitchers tend to age the worst? What sort of pitchers tend to age the best? With the section on knucklers in The Neyer/James Guide to Pitchers I can compare how those hurlers age compare to other pitchers. Do pitchers with better strikeout rates age better than others? Do pitchers with better control age better than others? Do pitchers in whose strikeout rates are in the top tenth percentile age better or worse than pitchers whose control are in the top percentile? Did deadballers age differently from liveballers? Did pre-1893 pitchers age differ from those who came since then?
CHRIS JAFFE is a Cubs fan and a graduate student working on his dissertation in American history. He has a website - http://runsupportindex.blogspot.com - which contains a great deal of the baseball stuff he farts around with.
