(AP) - Television ratings for baseball's division series are down from last year.

The 18 games on TBS, with all four series going the distance, averaged a 2.4 rating. That's down 11 percent from the 2.7 for 19 games in 2011, when teams from larger markets made the playoffs.

Three of the four series went the full five games last season.

MLB Network aired playoff games for the first time this year.

Its two division series broadcasts - Game 2 of Detroit-Oakland and Game 3 of St. Louis-Washington - averaged a network-record 1.2 million viewers, whereas two afternoon games on TBS last season averaged nearly twice that. MLB Network is in about 70 million homes to more than 100 million for TBS.

Ratings represent the percentage of all homes with televisions tuned into a program.
