Offense Ratio Concept

The offense ratio (OR) is the ratio of bases per out, and is calculated from total bases (TB), walks (BB), at bats (AB) and hits (H):
 
OR = (TB + BB) / (AB - H)

OR = BASES / OUTS

Every eligible player with a career OR greater than 1.0 and 2000 or more At Bats is in the Hall of Fame except Yankee power hitter Charlie "King Kong" Keller.

All but 12 eligible players with a career OR greater than 0.9 and 2000 or more At Bats are in the Hall of Fame.

Offense Ratio correlates very well with runs per game when calculated for teams and leagues, and therefore is an accurate indicator of the theoretical run production of an individual player.  Using the correlation between OR and runs per game (RPG) derived from combined league statistics (TB, BB, AB, and H) over time, the theoretical RPG for an individual player can be calculated from his OR.  This would be the runs per game that a nine man lineup consisting of just that player would score in the course of an average game.

Imagine being able to send Ted Williams to the plate over and over again for an entire game. Williams' career OR was 1.366.  A team with this OR would score an average of 10.8 runs per game.  By analogy, a lineup consisting of Williams alone would theoretically score 10.8 runs per game.  A box in the upper right hand corner of  the chart shows the relationship between OR and RPG.

Each curve on the Offense Ratio Diagram consists of all the points for which the combination of batting average and power average (total bases plus walks per hit) gives the same OR. The offense ratio that each curve represents is shown at the top of the curve.
