"Now, in Wizardry, comes the long-awaited breakthrough. Drawing solely on freely available baseball statistics, Michael A. Humphreys shows how to apply classic statistical methods to estimate runs saved by fielders going back to 1893. Humphreys tests his results against other fielding measures, including published ratings based on proprietary batted ball location data, and explains their respective strengths and limitations. He also introduces a method for adjusting historical player ratings for increased competition due to population growth, integration, and international recruitment. Position by position, Humphreys identifies and profiles the greatest fielders of all time with anecdote-rich essays."--Page 4 of cover.
