Is this metric on the same scale for batters and pitchers?
I have read that for batters it is plate appearances and for pitchers innings pitched.
Is this right?
Secondary to this, I have produced a query to calculate the number of runs/pa and runs/innings to get the league averages. For 2013 batting gives 20018/179361 whereas pitching gives 20255/43653.1. Why is there a discrepency in the runs ie 20018 to 20255?
I am trying to estimate the actual number of runs a batter and pitcher is worth per game to produce an estimate of the game score.
