Another lesser-known golfer, and no golfer name Tiger, contributed to double-digit preliminary declines in ratings for the PGA Championship over the week.

Keegan Bradley won the event, and CBS garnered a Nielsen preliminary 4.3 household rating -- 14% lower than a year ago when Germany's Martin Kaymer won the event. Tiger Woods' absence is noted by golf fans.

The PGA's rating peaked to a 6.6 household rating in the last half-hour (7:30 p.m. to 8:00 p.m.) due to an extra playoff round. It recorded a weak 1.8 rating/6 share among 18-49 viewers from 7 p.m. to 8 p.m.

Still, CBS won the night with under a 2 rating point score -- a 1.9 rating/5 share among 18-49 viewers. ABC was next with a 1.4/4; followed by Fox with a 1.2/4; Univision at a 1.1/3; and NBC with a 1.0/3.

The golf playoffs cause some disruption to CBS' prime-time schedule, which seems to have had an effect on ratings later in the evening.

CBS' big summer reality show "Big Brother" dipped 14% from the week before, to land around a 2.5/6. Still, this put the 9 p.m. show in the top spot when it came to all Sunday night broadcast shows. CBS' 10 p.m. new summer reality effort "Same Name" took in a 1.5/4, down a bit from the week before.

ABC's three-hour "CMA Music Festival: Country's Night to Rock" took a 1.6 rating/4 share among 18-49 viewers, down a bit versus the year before. ABC started the night with a special -- "i.a.m. FIRST: Science is Rock and Roll" -- getting a meager 0.5/2 and just over 2 million overall viewers.

Fox also tried its luck with some new stuff -- a sketch comedy series "In The Flow with Affion Crockett." It earned a 1.2 rating/3 share, well below that of the reruns of Fox's big animated comedies "The Simpsons" and "Family Guy."

All NBC's shows -- "Dateline NBC," "Minute to Win It" and two hours of "The Marriage Ref" -- each got to a preliminary 0.9 rating among 18-49 viewers.
