The structure of the Division Series is different from what has traditionally been the case. While they remain a best of five, it used to be that one league would begin before the other. This time, however, all four start on Tuesday with their Game 1’s. Wednesday then sees Game 2 only in the National League, and the American League get a day off, with the roles reversed on Thursday. The American League plays Game 2, while the National League teams are idle. Both leagues get a day off after Game 2 again, as the series switches to the other location.
