Although this year's American League Championship Series represents the two smallest market sizes in history, according to TBS, the Game 1 matchup Friday averaged 5.92 million total viewers for the network.
The total represented an increase of 9 percent from the National League Championship Series Game 1 telecast between the Los Angeles Dodgers and the St. Louis Cardinals on TBS last year, the network said Saturday. That game averaged 5.45 million total viewers, according to TBS.
The market sizes for Kansas City and Baltimore are 70 percent smaller than the market sizes for Los Angeles and St. Louis, based on available television households, according to TBS. In 2013, the number was 6.75 million, compared to 2.015 million this year.
This year's corresponding 3.6 U.S. household rating is up 3 percent over a 3.5 rating last year, and Friday night's telecast peaked with a 4.2 rating and 6.884 million total viewers between midnight and 12:15 a.m. ET, according to the network. And TBS said Friday night's telecast saw "significant growth across all key demos," including an 11 percent climb among people 18 to 49 years old.
Locally, the game received a 22.9 household rating, the highest since the AL Division Series Game 3 in 2012 against the New York Yankees, which had a 23.6.
