SABR Defensive Index rankings released through August 10, 2025
AUGUST 15, 2025 — San Diego right fielder Fernando Tatis Jr. and Boston right fielder Wilyer Abreu lead their respective leagues in the updated SABR Defensive Index™ rankings through Major League Baseball games of Sunday, August 10, 2025.
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.
Tatis’s SDI of 15.3 leads all fielders in the NL, followed by Cincinnati third baseman Ke’Bryan Hayes (14.2) and San Francisco catcher Patrick Bailey (12.1). Chicago center fielder Pete Crow-Armstrong (11.5) and Atlanta first baseman Matt Olson (11.3) round out the top five.
Abreu’s SDI of 11.4 is the highest in the AL among all qualified defenders, ahead of teammate and Boston center fielder Ceddanne Rafaela (10.1), Cleveland left fielder Steven Kwan (9.4), Toronto catcher Alejandro Kirk (8.9), and Tampa Bay shortstop Taylor Walls (8.6).
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 2025 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; Joe Rosales of Sports Info Solutions; Tom Tango, MLB’s Senior Data Architect; author and defensive metrics expert Chris Dial; and author Michael Humphreys.
