In 1954 Branch Rickey wrote an article for Life Magazine entitled “Goodbye to Some Old Baseball Ideas.” [1] Rickey criticized some traditional baseball statistics and proposed some of his own, which included formulas for team offense and pitching efficiency. For individual hitting Rickey recommended the sum of on-base average (OBA) plus extra base power (EBP). These were defined as
$$\begin{array}{l} OBA = \frac{{hits + bases\;on\;balls + hit\;by\;pitcher}}{{at bats + bases\;on\;balls + hit\;by\;pitcher}},\\ EBP = \frac{{total\;bases - hits}}{{at bats}} \end{array}$$
