Stat of the Week: RA

RA, or Run Average, is the number of runs (earned and unearned) allowed by a pitcher or team per 9 innings. Considering all runs allowed by a pitcher is more desirable from a predictive standpoint because it adjusts the arbitrary format of official scoring and the attribution, the problems of reconstructing an inning to determine unearned runs, and the small number of errors presently compared to the past that would normally be seen when measuring pitcher success through just an “earned runs” method. A pitcher good at preventing earned runs tends to be good at preventing unearned runs.
