I don't fully understand PRAA and PRAR and would like someone to explain something to me. How exactly is it calculated and is the end result based on an average number of innings? Like, say is a 42 PRAA equal to being 42 runs above average per every 100 innings? Or does that mean you were 42 runs above average for the innings you pitched?
If it's the latter I have to strongly diagree with the outcome. If Papelbon was 41 runs above averages for the innings he pitched then that would put the average closer/reliever at a 6.7 ERA. That is absurd.
