Defensive Runs Saved (DRS) is one of the most popular advanced measures of fielding prowess. But how does it work? Mark and Andy break down the stat and look at the best and worst fielders as measured by DRS. You may be surprised at the results. Finally, join in a round of Roll The Stat and beat the hosts at their own game with your newfound expertise.
