  • Relative OPS??

    Is Relative OPS a real stat?

    I kno to get Rel. Ba its Ba/LgBa

    Rel. Ob is OB/LgOB

    Rel. Slg is Slg/LgSlg

    so why not

    Ops/LgOps

    And if so is it a useful stat?

    OPS+ at www.baseball-reference.com

    100 * (OBP / lg OBP + SLG / lgSLG -1)

    100 is average

      Ok so Rel. Ops is basically OPS+

      And why the -1 in the equation?

        The minus one is because you are adding two numbers that are both based on a 100 point scale and then you wish to have a final number on a 100 point scale as well.

        Each part of the equation is seperate and then added together. So a player who is 8% better then league average in OBP would have a rel OBP of 108 and if he was 15% better in SLG then he would have a 115. Add the two together and you get 223. Subtract 100 and you get 123. Now one thing to remember is that OPS+ is not a % stat. Meaning that player's OPS+ isn't 23% better then average, his components % when added come to 23% but that doesn't mean he is 23% betten then average.

        For example let say the lg average is .300 in OBP and .400 in SLG, and player A has .350 and .450. His OPS is 14% better then average, but his components are 17% and 13% better respectively. SO his OPS+ would not be 114 but 129.

          Doesn't the OPS+ used at baseball-reference also include a park adjustment when finding the league averages?
