Estimating Fielding Ability in Baseball Players Over Time

  title={Estimating Fielding Ability in Baseball Players Over Time},
  author={James M Piette and Shane T. Jensen},
  journal={Journal of Quantitative Analysis in Sports},
Abstract Quantitative evaluation of fielding ability in baseball has been an ongoing challenge for statisticians. Detailed recording of ball-in-play data in recent years has spurred the development of sophisticated fielding models. Foremost among these approaches, Jensen et al. (2009) used a hierarchical Bayesian model to estimate spatial fielding curves for individual players. These previous efforts have not addressed evolution in a player’s fielding ability over time. We expand the work of… 
Predictors of fielding performance in professional baseball players.
Spring-training measurements of VJMP and proagility time may predict the defensive run value of a player over the course of a professional baseball season.
nflWAR: a reproducible method for offensive player evaluation in football
The R package nflscrapR is developed to provide easy access to publicly available play-by-play data from the National Football League (NFL), and a novel multinomial logistic regression approach for estimating the expected points for each play is introduced.
SEAM methodology for context-rich player matchup evaluations
The SEAM (synthetic estimated average matchup) method for describing batter versus pitcher matchups in baseball is developed, both numerically and visually, and novel performance metrics that are calculated as expectations taken with respect to the spray chart distribution are provided.
Uncovering Formula One driver performances from 1950 to 2013 by adjusting for team and competition effects
This is the first objective method for comparing Formula One drivers that has yielded sensible results and adds a valuable perspective to previous subjective analyses.
Improved component predictions of batting and pitching measures
Standard measures of batting performance such as batting average and on-base percentage can be decomposed into component rates such as strikeout rates and home run rates. The likelihood of hitting
Improved Component Predictions of Batting Measures
Standard measures of batting performance such as a batting average and an on-base percentage can be decomposed into component rates such as strikeout rates and home run rates. The likelihood of


Bayesball: A Bayesian Hierarchical Model for Evaluating Fielding in Major League Baseball
This work combines spatial modeling with a hierarchical Bayesian structure in order to evaluate the performance of individual fielders while sharing information between fielders at each position.
Scoring and Shooting Abilities of NBA Players
The results show that a combination of SCAB and SHTAB can be used to separate out players based on their offensive game, and players who are highly ranked according to these measures are regularly considered as top performers on offense by experts.
Modeling Baseball Player Ability with a Nested Dirichlet Distribution
The nested Dirichlet probability distribution is introduced and a method of using it to model Major League Baseball player abilities is proposed, leading to surprising new evidence that the underlying abilities of players (not just their statistical performances) are mean-reverting in some sense.
A Spatial Analysis of Basketball Shot Chart Data
H hierarchical spatial models are developed for shot-chart data, which allow for spatially varying effects of covariates and permit differential smoothing of the fitted surface in two spatial directions, which naturally correspond to polar coordinates.
Baseball Errors
This paper examines the factors that determine the rate of errors called in major league baseball, and changes in the error rate over time. We find that (1) the rate of errors depends on the quality
Univariate and Multivariate Autoregressive Time Series Models of Offensive Baseball Performance: 1901-2005
This paper sets out to estimate univariate time series models on a selected set of offensive baseball measures from 1901 to 2005. The measures include homeruns, bases on balls, runs batted in,
The Bill James Historical Baseball Abstract
When Bill James published his original "Historical Baseball Abstract" in 1985, he produced an immediate classic, hailed by the "Chicago Tribune" as the holy book of baseball. Now, baseball's beloved
The Book: Playing the Percentages in Baseball
Written by three esteemed baseball statisticians, "The Book" continues where the legendary Bill James' "Baseball Abstracts" and Palmer and Thorn's "The Hidden Game of Baseball" left off more than
Bayesian analysis of binary and polychotomous response data
Abstract A vast literature in statistics, biometrics, and econometrics is concerned with the analysis of binary and polychotomous response data. The classical approach fits a categorical response
Proper multivariate conditional autoregressive models for spatial data analysis.
This work introduces spatial autoregression parameters for multivariate conditional autoregressive models and proposes to employ these models as specifications for second-stage spatial effects in hierarchical models.
