The only Series with fewer average viewers were Philadelphia's five-game win over Tampa Bay in 2008 (13,062,000), San Francisco's four-game sweep of Detroit in 2012 (12.7 million) and the Giants' seven-game win over Kansas City in 2014 (13,825,000). The rating was the third-lowest, ahead of only a 7.6 in 2012 and an 8.2 in 2014.
