This paper analyzes Branch Rickey’s 1954 equation in a regression context. The results for 1934–1953 are consistent with Rickey’s conclusions, and the equation holds up well when extended 51 years. Two of the main conclusions are that on-base percentage dominates batting average and that oﬀense and defense are equally important. Perhaps Rickey was as good as he thought he was?
