Average Game Scores For Indians Pitchers: Graphics!

by afh4 on Sep 21, 2010 5:08 PM EDT in Analysis

In an idea cribbed from Royals Review, I'm charting the Indians pitchers by game scores. Game score is a simple metric developed by Bill James that defines a quality start as above 50. A perfect game score would be a 114. The link will tell you much more if you so desire. In the charts below, you will see along the horizontal x-axis the start number for each pitcher (note that each graph starts with the pitcher's first start, not the beginning of the season) and along the vertical y-axis the game score. All of the game score data was collected from baseball-reference.

I've done the chart for each pitcher and then, at the end, added two relatively obvious comparisons. Seeing the charts this way allows us to see if a pitcher got less or more effective over the course of the season or in any particular stretch. For another reference on pitcher effectiveness, I'm going to include average season game score here:


Pitcher	Average
Carmona	51.67
Masterson	46.72
Westbrook	50.27
Talbot	46.54
Huff	39.87
Tomlin	48.60
Gomez	43.30
Laffey	47.20
Carrasco	57.25

I suspect others will have greater insight than I, but, for starters, it stands out that only two pitchers that have averaged a QS will finish with Cleveland and one of them carries a small sample size caveat. I have no idea what the average is for all teams (or good teams) but this seems like a bad thing. On to the charts:

Everybody!

Note: The "65" above denotes Jake last's game in Cleveland, where his GS was 65.

Masterson/Talbot

Gomez/Tomlin

Just a quick comment. It would be help full if all the charts had the same y range. As it is the go from a max of 70 to a max of 100.

Apologies. Fixed now. My Excel game is weak, currently.

Except for the final graph, which is an internal comp anyway.

Geez help full – my spelling/grammar game appears to be weak too.

Very nice work. I appreciate the background on the “stat” and the presentation of the graphs makes it easy to see the ups and downs of a season. Makes that old saying that a pitcher will have 30 starts a year, about 5 excellent, 5 awful, and its the other 20 that define the pitcher.
