Postseason Baseball Draws Viewers, Nearly $109M In TV Ad Spend

What improved? Initial postseason “wild card” games. The biggest was the New York Yankees-Boston Red Sox game -- one of the more storied rivalries -- which averaged 7.1 million viewers.

The other wild-card contest was second-best so far this postseason: St. Louis Cardinals-Los Angeles Dodgers, averaging 6.7 million viewers.
