Bet it has been an interesting morning for CBS.

Given what has transpired, it seems to be an appropriate time to discuss Tiger Woods’ impact on the ratings at the Masters.

Earlier this week, CBS Sports President Sean McManus said in a conference call that the Tiger effect wasn’t as profound at Augusta National.

“It’s very documented the kind of spike you get when Tiger Woods is in contention,” McManus. “During a regular PGA Tour event, that can be anywhere from a 100 to 200 percent increase. It’s not as dramatic at Augusta. The Masters traditionally is the most-watched event of the year. There’s no question if he is in contention, we’ll get a spike.

“The good news is that even (when Woods isn’t in the hunt), the ratings have been pretty darned good. If he’s not in contention, I’m still confident we’ll get a terrific rating.”

The ratings always are strong, but you have to keep one thing in mind: Woods contends almost every year. Since 2005, Woods only has one sub-top 6 finish at the Masters; he placed 40th last year. He won in 2005; was second in 2007, 2008; and fourth in 2010, 2011.

Last year, when Woods stumbled badly, the ratings did take a hit. Sunday’s final round did an 8.0 rating, down from 9.5 in 2011; CBS’ two-day average for the weekend was 6.8, down from 8.2 in 2011.

In 2010, when Woods made his comeback following his “troubles,” the rating was 10.7 on Sunday, and 9.0 over the weekend for CBS.

So McManus is correct in the sense that Woods doesn’t produce a 100 percent bump in the ratings at the Masters. However, there was a 16 percent drop in last year’s final round from 2011 and 25 percent compared to 2010.

Those still are significant decreases. They gave CBS ample reason to hope Woods shows up for his 1:45 p.m. (ET) tee time this afternoon.
