We present sophisticated methodology for the analysis of fielding performance in major league baseball. Our approach is based upon high- resolution data consisting of on-field location of batted balls. A key issue is the balance between the personal performance of an individual fielder and the shrinkage to the population performance of similar fielders. We combine spatial modeling with a hierarchical Bayesian structure in order to evaluate individual fielders while sharing information between fielders at each position. We present results across seven seasons of MLB data and compare our approach to other fielding evaluation procedures.
