For the ninth consecutive season, the SABR Defensive Index will be 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 Information Solutions data, and STATS, LLC 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.

Lindor’s SDI of 4.6 is the highest in the NL among all qualified defenders, ahead of San Diego second baseman Jake Cronenworth (4.4), Colorado third baseman Joshua Fuentes (4.1), and a pair of Pittsburgh teammates, shortstop Kevin Newman and third baseman Erik Gonzalez (both 3.6).

Tucker’s SDI of 4.6 leads all fielders in the AL, followed closely by Kansas City center fielder Michael A. Taylor at 4.5. Minnesota center fielder Byron Buxton (4.1), Chicago pitcher Dallas Keuchel (4.1), and Minnesota shortstop Andrelton Simmons (3.9) 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 2021 season at The SDI is compiled by the SABR Defensive Committee, which includes former SABR Board President Vince Gennaro; Sean Forman of; Ben Jedlovec, MLB’s Director of Engineering, Data Quality; SABR Director F.X.
