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 6.3 is the highest in the NL among all qualified defenders, just ahead of Colorado third baseman Joshua Fuentes (6.1). Rounding out the top five are San Diego third baseman Manny Machado, Pittsburgh catcher Jacob Stallings, and Miami right fielder Adam Duvall, all at 4.7.

Chapman’s SDI of 6.5 leads all fielders in the AL, followed by Texas right fielder Joey Gallo (6.0), Tampa Bay center fielder Brett Phillips (5.0), Chicago pitcher Dallas Keuchel (5.0), and Toronto second baseman Marcus Semien (4.8).

The updated SDI results were released today by the Society for American Baseball Research.
