Ok, I give up. WTF is (are?) “Game Scores?”
An attempt to objectively evaluate a pitchers performance in a game.
From Wiki:Game Score is a metric devised by Bill James to determine the strength of a pitcher in any particular baseball game. To determine a starting pitcher's game score:
Start with 50 points.
Add one point for each out recorded, so three points for every complete inning pitched.
Add two points for each inning completed after the fourth.
Add one point for each strikeout.
Subtract two points for each hit allowed.
Subtract four points for each earned run allowed.
Subtract two points for each unearned run allowed.
Subtract one point for each walk.
There is a newer version that I think fangraphs uses that treats all runs the same and punishes you if you give up a HR. I am not sure which model he used for these scores.
