SAN DIEGO (AP) -- Tiger Woods couldn't beat himself in the TV ratings.

In the first network golf coverage of the year, CBS got a 4.6 overnight rating from Sunday's final round at Torrey Pines, where Woods led by as many as 11 shots before winning by eight for his fourth consecutive Buick Invitational title.

It was golf's highest rating since the PGA Championship last August, but still down 18 percent from the Buick Invitational a year ago, when Woods held off Charles Howell III over the final holes to win by two. The final round last year drew a 5.6 overnight rating.

The overnight rating for Saturday was 3.2, up 28 percent from the third round last year.

"We were up Saturday," said Rob Correia, senior vice president of programming for CBS. "Obviously, it was a blowout, but it will still end up being one of the highest-rated TOUR events on a Sunday. We have no complaints."

Overnight ratings measure the 55 largest TV markets in the United States. The rating is the percentage watching a program among homes with televisions.

National ratings were expected later in the week.
