Giants vs Pirates

Using the WAR ratio I used for the Oakland vs Kansas City game the Giants appear to have a slight advantage.

Giants offense has a WAR of 19.7
Pirates offense has a WAR of 29.5

Madison Bumgarner has a WAR of 4.0
Edison Volquez has a WAR of 2.5

That give the Giants a ratio of .135 and the Pirates a ratio of .126.
