Give some stream of consciousness and then the answer. The Cubs defeated the Indians when they won 4 games to 3 to win their first World Series since 1908. Game 7, an 8 -- 7 victory in extra innings, marked the fifth time that a Game 7 had gone past nine innings and the first since 1997 (which, coincidentally, also featured the Indians). It was also the first to have a rain delay which occurred as the tenth inning was about to start. The Cubs became the sixth team to come back from a 3-1 deficit to win a best-of-seven World Series, following the 1925 Pittsburgh Pirates, the 1958 New York Yankees, the 1968 Detroit Tigers, the 1979 Pittsburgh Pirates, and the 1985 Kansas City Royals. This was the second time and the first since 1948 where the World Series score was even.
