Ben Lindbergh, writing for Grantland, discusses a “Bullpen Management Above Random” statistic, to see which managers were best in baseball at managing their bullpen, and Joe Girardi has continually ranked near the top in this stat.
Matheny — who told USA Today’s Ted Berg in April that he uses three-year statistical stats as a “tiebreaker” when making bullpen moves but believes that managers “first and foremost have to trust our gut” — ranks at the bottom over a multiyear sample as well as in 2015.
