What is RELIEF RUN AVERAGE® relief quotient?
RELIEF RUN AVERAGE® (abbreviated R.R.A.®) relief quotient is a baseball statistic that measures the ability of a relief pitcher to prevent inherited base runners from scoring.
What is an inherited base runner?
An inherited base runner is any player who is already on base when a relief pitcher enters the game.
How does the R.R.A.® relief quotient evaluate the ability of a relief pitcher?
The most important factor that R.R.A.® takes into account is how many inherited base runners a relief pitcher allows to score, either over the course of a game, week, month, season or career.
How is R.R.A.® measured?
R.R.A.® is measured with a number that can be as low as zero. A higher number reflects an inability to hold inherited runners on base. Relief quotient figures are comparable to ERA figures. So, 0. is perfect, 1.0 is excellent, 2.0 is very good, 3.0 is good, 4.0 is fair, etc.
What else factors into measuring R.R.A.®?
In addition to the number of inherited base runners that are allowed to score, there are 2 other variables involved in calculating R.R.A.® The first is the bases of any inherited runners when the relief pitcher enters the game. The second is the number of outs there are when the relief pitcher enters the game.
How is R.R.A.® calculated?
