Fast National ratings for Sunday, August 10, 2014.

The tight conclusion to the golf calendar's final major, featuring many of the sport's biggest names, stretched two full hours into primetime on Sunday, preempting "Unforgettable" and "Reckless," but leading CBS to domination in all measures.

CBS' only Sunday originals were a golf-bloated "60 Minutes" and "Big Brother," which delivered below-average numbers in a 10 p.m. airing for much of the country. 

Sunday's other semi-major notable was FOX's Teen Choice Awards telecast, which appears to have been basically flat with last year's show.

On to the numbers, which are very subject-to-change...

Among adults 18-49, CBS averaged a 2.0 rating for Sunday primetime, tops in the key demographic. ABC, NBC and FOX all averaged a 0.8 key demo rating for the night.

Overall, CBS averaged an estimated 9.025 million viewers and a 5.7 rating/10 share for Sunday night, far ahead of the 3.65 million viewers and 2.2/4 for ABC. NBC's 3.28 million viewers and 2.0/4 topped FOX's 2.24 million viewers and 1.3/2.

[For whatever it's worth, FOX dominated the night among viewers 12-17, topping the combined totals for the other three networks.]
