SABR Defensive Index rankings released through August 13, 2023
AUGUST 18, 2023 — San Diego right fielder Fernando Tatis Jr. leads the major leagues in the updated SABR Defensive Index™ rankings through games of August 13, 2023.
The SABR Defensive Index is used to help select the winners of the Rawlings Gold Glove Award® and Rawlings Platinum Glove Award™, presented by SABR.
The SDI 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. SDI utilizes MLBAM’s Statcast, Sports Info Solutions data, and STATS Perform data as well as traditional statistics with advanced analysis.
The SABR Defensive Index accounts for approximately 25 percent of the Rawlings Gold Glove Award selection process that will be added to the votes from the managers and coaches. The updated SDI results were released today by the Society for American Baseball Research.
The final SDI results will be released following the conclusion of the 2023 season at SABR.org. The SDI is compiled by the SABR Defensive Committee, which includes former SABR Board President Vince Gennaro; Sean Forman of Baseball-Reference.com; Mark Simon of Sports Info Solutions; Ben Jedlovec, MLB’s Senior Director, Baseball Data Platform Product; former SABR Director F.X. Flinn; author and defensive metrics expert Chris Dial; and author Michael Humphreys.
