Advanced Stats 102: GSc

sabermetrics
We are going to continue today with pitching stats. Game Score (GSc). This is one of the most simple statistics out there, and really easy to calculate. However, it’s simplicity is what makes this a very useful stat. It is used to gauge the performance of starting pitcher over one game.

GSc (Game Score)

This is one of my favorite baseball statistics. It was developed by the great Bill James to measure a pitcher’s single outing. It’s a very simple stat, but one that has an incredible outlook on a single performance. There really isn’t much to breakdown with Game Score, because of it’s simplicity. When you think GSc, think NFL quarterback rating. Here is how to calculate it:

1. Start with 50 points.
2. Add 1 point for each out recorded, so 3 points for every complete inning pitched.
3. Add 2 points for each inning completed after the 4th.
4. Add 1 point for each strikeout.
5. Subtract 2 points for each hit allowed.
6. Subtract 4 points for each earned run allowed.
7. Subtract 2 points for each unearned run allowed.
8. Subtract 1 point for each walk.

The highest game score in 2012 was 101, by Matt Cain in his perfect game. For the Rangers the highest GSc recorded in 2012 was Derek Holland with 83 on September 7th in a loss to Tampa 1-3. Not surprisingly, the lowest GSc was also Derek Holland on May 30th in the 8-21 beating by Seattle.
