SABR Defensive Index


Beginning in 2013, the SABR Defensive Index™ has been used to help select the winners of the Rawlings Gold Glove Award® and Rawlings Platinum Glove Award™, which is presented by SABR.

The SABR Defensive Index draws on and aggregates two types of existing defensive metrics: those derived from batted ball location-based data and those collected from play-by-play accounts. The three metrics representing batted ball data include Defensive Runs Saved from Baseball Info Solutions, Ultimate Zone Rating developed by noted sabermetrician Mitchel Lichtman, and Runs Effectively Defended based on STATS Zone Rating and built by SABR Defensive Committee member Chris Dial. The two metrics included in the SDI originating from play-by-play data are Defensive Regression Analysis, created by committee member Michael Humphreys, and Total Zone Rating.

The SABR Defensive Index accounts for approximately 25 percent of the Rawlings Gold Glove Award selection process that was added to the votes from the managers and coaches.

Rawlings announced the revised selection process overview in March 2013 at the annual SABR Analytics Conference as part of its new collaboration with SABR. Since that announcement, SABR enlisted an independent committee of experts in baseball analytics and defensive measurement to devise the SDI. The SABR Defensive Committee includes:

  • Committee chair Vince Gennaro, SABR President and author of Diamond Dollars: The Economics of Winning in Baseball
  • Sean Forman, founder of Baseball-Reference.com
  • Ben Jedlovec, Baseball Info Solutions
  • Chris Dial, author and recognized expert on defensive metrics
  • Michael Humphreys, author of Wizardry: Baseball’s All-Time Greatest Fielders Revealed
  • F.X. Flinn, SABR Board of Directors
