Tiger Woods is 50-1 long shot

Fifty to 1.

That's the number that is next to Tiger Woods' name when the odds for the Farmers Insurance Open hit the electronic board Monday at the Westgate Las Vegas SuperBook.

It's a number that the book's assistant manager, Jeff Sherman, doesn't recall ever seeing for Woods -- and Sherman's job of setting golf odds has spanned Tiger's entire career.

"Tiger always commanded money, so the idea was that even though at times it might be a true 80-1 for him to win, he'd still be at 20-1 because people would still bet on him at that," Sherman said.

But Sherman said after Tiger carded an 82 on Friday at the Waste Management Phoenix Open, his worst round as a pro, the odds had to seriously be adjusted for this week's tournament at Torrey Pines.

That's despite the fact Woods has won at Torrey eight times through his career.

"We had to react drastically because there was a really negative reaction to the way he played," Sherman said. "I mean, there will be some people who won't even touch him at 50-1. But we do expect that would be a number where we will have some liability."

Issues with Woods' back led to the golfer making only nine total starts last year. He missed the cut at the PGA Championship in his last official event of 2014 and finished last in his own Hero World Challenge at year's end. Woods hasn't won on the PGA Tour since prevailing at the Bridgestone Invitational in August 2013.

Sherman said he also dropped future odds for Woods, including his odds to win the Masters from 12-1 to 20-1.

Woods was 30-1 to win the PGA Championship last year, the longest odds that were ever placed on Woods in his career.

Sherman posted the odds of Woods winning all four majors this year at 500-1.

"When he was healthy, we'd get people making that bet at 50-1," Sherman said. "So the odds for him to win the Grand Slam are now are 10 times what they were when he was doing well."

Woods' last major win was the 2008 U.S. Open.
