SABR Defensive Index

SABR Defensive Index rankings released through July 13, 2025

JULY 18, 2025 — San Diego right fielder Fernando Tatis Jr. and Boston center fielder Ceddanne Rafaela lead their respective leagues in the updated SABR Defensive Index™ rankings through Major League Baseball games of Sunday, July 13, 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.

Rafaela’s SDI of 9.4 is the highest in the AL among all qualified defenders, ahead of Tampa Bay shortstop Taylor Walls (9.0), Cleveland left fielder Steven Kwan (8.2), Boston catcher Carlos Narváez (8.0), and Houston shortstop Jeremy Peña (7.3).

Tatis’s SDI of 12.1 leads all fielders in the NL, followed by Atlanta first baseman Matt Olson (10.1) and San Francisco catcher Patrick Bailey (9.1). A pair of Chicago Cubs teammates, second baseman Nico Hoerner (8.7) and center fielder Pete Crow-Armstrong (8.3), round out the top five.

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.
