Okay, let’s play a stupid game. Without looking, which Royals relievers finished 1st and 2nd in fWAR? If you guess Ian Kennedy and Scott Barlow, congrats! Now if you set the minimum innings to 70, who is first? It’s Scott Barlow. You are great at this game, reader!

On a WAR/80IP basis, Scott Barlow was the second best pitcher on the staff (though to be fair, WAR is an accrual stat so pitching a lot is good).
Among all relievers, Barlow actually finished ~30th in baseball in WAR thanks to a good strikeout rate (31% above league average) and an excellent home run rate (47% below league average).
