Method, apparatus and system for determining player effectiveness

Abstract

A method of evaluating the effectiveness of a baseball player or group of players, considering offensive inputs such as at bats and batting, base running and advancing other base runners and other baseball performances. This method reduces the baseball player effectiveness to a single number, or average. This average would be kept and updated over a series of baseball player at-bats and used to compare to other performances, such as other series of at-bats, seasons, or other players, or teams.

1 . A means of-evaluating the efforts of a baseball player, or group of baseball players, comprising of: 
 a. a numerator consisting of counting the bases advanced from the efforts of a particular offensive baseball player, or group of baseball players, which includes the bases reached by that particular offensive baseball player, or group of basebalI players, which usually is/are the batter/s, and adding to that any bases advanced by other offensive baseball players already on base which advanced because of the efforts of that one particular offensive player, or group of players, which again is/are usually the batter/s, and    b. a denominator consisting of the total official at-bats for the same period of time for which said numerator was recorded, and    c. dividing said numerator by said denominator whereby creating a number, an average, used to compare other offensive baseball performances, and, in combination,    d. at the discretion of the user, adjusting either said numerator, said denominator, and/or said average by other means to finely adjust said average by selecting from the group consisting of advantages or disadvantages of batting order, differences in ball parks, defensive fielding position, intentional walks, errors, sacrifices and/or any other function of baseball which may add to the accuracy and usefulness of said average.
