Outs Above Average (OAA)
is the cumulative effect of all individual plays a fielder has been credited or debited with, making it a range-based metric of fielding skill that accounts for the number of plays made and the difficulty of them. For example, a fielder who catches a 25% Out Probability play gets +.75; one who fails to make the play gets -.25.
