A statistic in baseball that estimates the number of runs attributable to a hitter by looking at their contributions at bat and on the bases. There are various different calculations for Runs Created as the statistic has evolved over time.
RC = (H + BB) x TB / (AB + BB)
Created by Bill James with the goal of creating a statistic that illuminates the run contribution of a hitter from both their actions at base and on the bases. More general stats like hits, runs batted in, home runs, etc. only provide part of the run picture while this stat attempts to provide a clearer picture.
