Abstract

This paper combines an estimated expected run value equation with a probability model on the outcome of batted balls to isolate the game within a game. Using linear regression we were then able to determine the percentage of the outcome of an at bat that is controlled by a pitcher and the percentage that is controlled by the batter.
