Bill James, who is something of an ass these days after years spent developing the idea of sabermetrics, once created the idea of game score to begin to quantify how good certain pitchers were in their respective outings. Of the idea, he once described it as “a kind of garbage stat that I present not because it helps us understand anything in particular but because it is fun to play around with,” and after Tyler Mahle posted a 93 in his outing on Monday evening against Arizona, it’s once again a fun stat to play around with around here.
