On the heels of the Craig Calcaterra-inspired “7-3 score day” post, there was a request for the most frequent final scores in baseball history. Fortunately, the VORG is prepared with the Retrosheet game logs of most every contest from 1871-2010, so one crosstab of home and visitor scores later, and I’ve determined there have been approximately 611 unique final scores (from many instances of 0-0 up to one game on June 28, 1871 that ended 49-33).
Here is the top 10 (combined totals based on either team winning):
The 1-run games should and do favor the home team (from 1901-2011, they’ve won 61% of such games), as any tie game in the ninth (or beyond) need only see the home team push across a single run. The situation of the road team winning the slight majority of 5-3 games is actually well within the realm of possibility, as road teams have won 50.1% of 2-run games since 1901.
