SABR Defensive Index rankings released through July 12, 2015
JULY 24, 2015 — Tampa Bay center fielder Kevin Kiermaier and Colorado third baseman Nolan Arenado have opened commanding leads in the SABR Defensive Index™ rankings through the first half of the 2015 season.
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 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 15.0 is the best in the game among all qualified defenders, ahead of Baltimore third baseman Manny Machado (8.3), Detroit second baseman Ian Kinsler (8.2), Toronto third baseman Josh Donaldson (8.0), and Detroit left fielder Yoenis Cespedes (7.0).
Arenado’s SDI of 10.9 through July 12 is the top figure in the NL, ahead of Washington second baseman Danny Espinosa and Atlanta shortstop Andrelton Simmons, both with 8.1. Rounding out the top five are Colorado second baseman D.J. LeMahieu (7.8), along with Miami shortstop Adeiny Hechavarria and New York right fielder Curtis Granderson (tied at 6.6).
The SDI results were released today by the Society for American Baseball Research.
Updated SDI results will be released periodically throughout the rest of the 2015 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.
