It’s the 50th anniversary of the founding of SABR – Society for American Baseball Research. To celebrate, SABR offers 50 moments in the evolution of baseball analytics for the past 50 years. This is a great piece for people to learn important moments in the game’s history from a non-player point of view. What makes it even better is that it recognizes contributions from our own Chris Dial.
Beginning in 2013, the SABR Defensive Index was added to help select the winners of the Rawlings Gold Glove Award and Platinum Glove Awards — as both a “voter” and by having the numbers shared with all managers and coaches who make up the rest of the voters. SDI is an aggregation of the most prominent existing defensive metrics: Baseball Info Solutions’ DRS, Mitchel Lichtman’s UZR, Chris Dial’s RED, Michael Humphrey’s Defensive Regression Analysis, and Sean Smith’s Total Zone Rating.
