SEPTEMBER 15, 2014 — The hot corner is the hot spot for the AL leaders in the SABR Defensive Index™ rankings. Oakland third baseman Josh Donaldson and Seattle’s Kyle Seager continue to battle for the league lead in the AL, while Atlanta’s Jason Heyward has maintained a steady lead in the NL through games of September 7, 2014.
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.
This is the final in-season update of the SDI rankings and includes all 2014 qualifiers who will appear on the Rawlings Gold Glove Award ballot sent to managers and coaches. The SABR Defensive Index accounts for 30 total “votes” — or approximately 25 percent of the Rawlings Gold Glove Award selection process — which are added to the votes from the managers and coaches.
The SABR Defensive Index 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. The three metrics representing batted ball data include Defensive Runs Saved from Baseball Info Solutions, Ultimate Zone Rating developed by noted sabermetrician Mitchel Lichtman, and Runs Effectively Defended based on STATS Zone Rating and built by SABR Defensive Committee member Chris Dial. The two metrics included in the SDI originating from play-by-play data are Defensive Regression Analysis, created by committee member Michael Humphreys, and Total Zone Rating.
Donaldson’s SDI of 20.2 is the top figure in the AL, ahead of Seattle third baseman Kyle Seager (17.7), Kansas City left fielder Alex Gordon (16.2), and a pair of Boston teammates: second baseman Dustin Pedroia (12.9) and center fielder Jackie Bradley Jr. (10.4).
Heyward’s SDI of 27.2 through September 7 is the best in the game among all qualified defenders. The top five NL players as ranked by SDI, after Heyward, are: New York center fielder Juan Lagares (17.9), Cincinnati shortstop Zack Cozart (14.2), Colorado third baseman Nolan Arenado (11.2) and Cincinnati center fielder Billy Hamilton (11.2).
The SDI results were released today by the Society for American Baseball Research.
The final SDI results will be released following the conclusion of the 2014 regular season at SABR.org. The SDI is compiled by the SABR Defensive Committee, which includes SABR President Vince Gennaro, Sean Forman of Baseball-Reference.com, Ben Jedlovec of Baseball Info Solutions, SABR Director F.X. Flinn, author and defensive metrics expert Chris Dial, and author Michael Humphreys.
