SABR Defensive Index rankings released through September 13, 2015

SEPTEMBER 18, 2015 — Tampa Bay center fielder Kevin Kiermaier continues to hold a strong lead in the AL and San Francisco shortstop Brandon Crawford has retained the NL’s top spot in the SABR Defensive Index™ rankings through games of September 13, 2015.

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 2015 qualifiers who will appear on the Rawlings Gold Glove Award ballot sent to 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.

The SABR Defensive Index accounts for approximately 25 percent of the Rawlings Gold Glove Award selection process that was added to the votes from the managers and coaches.

Kiermaier’s SDI of 26.7 is the best in the game among all qualified defenders, ahead of Baltimore third baseman Manny Machado (12.4), Toronto center fielder Kevin Pillar (10.8), Detroit left fielder Yoenis Cespedes (9.9 — AL numbers only), and Kansas City center fielder Lorenzo Cain (9.2).

Crawford’s SDI of 16.8 through September 13 is the top figure in the NL, ahead of Colorado third baseman Nolan Arenado (13.2), Miami shortstop Adeiny Hechavarria (11.6), San Francisco first baseman Brandon Belt (11.1), and St. Louis right fielder Jason Heyward (10.2).

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 2015 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.
