Back in early December 2018, Baseball Prospectus unveiled a new metric called Deserved Runs Created Plus, abbreviated simply as DRC+. Here is a brief explanation from Baseball Prospectus noting the difference between this newly released metric and its predecessors that are currently available to the public.
DRC+ differs from other (public) hitting metrics in that it focuses on each hitter’s expected contribution, rather than merely averaging the result of hitter PAs.
Based solely on the name and abbreviation, DRC+ may appear like an updated version of the commonly used wRC+ (Weight Runs Created Plus) from FanGraphs.
