The 11.1 national average (12.1 million homes) for White Sox vs. Astros trailed the previous low, an 11.9 rating for Anaheim vs San Francisco in 2002.
Red Sox encounter with Cardinals last season averaged a 15.8.
However, most non-cable ratings have declined in recent years and broadcaster Fox still beat other networks all four nights during the World Series. It also beat this year's Spurs-Pistons NBA Finals rating on ABC (8.1 average).
Also, because of power outages caused by Hurricane Wilma, it had not been possible to determine ratings in the South Florida region.
