Phil Mickelson getting most Masters bets in Las Vegas

Phil Mickelson getting the Tiger Woods' public-type bets.

There's no Tiger Woods in this years Masters, but action is still pouring in at a record pace at the Westgate Las Vegas SuperBook for the first major of the season which tees off on Thursday morning.

SuperBook assistant manager Jeff Sherman says Tiger is always good for business, but there are enough storylines to keep bettors satisfied for what is annually the largest wagered golf tournament.

"By far," Sherman said of their Masters handle compared to other majors. "We're going to surpass last year (which was the highest). We're on pace to do it."

With Woods not in play on the board -- he was the largest wagered upon golfer in last year's Masters and largest risk Sherman ever saw for a golfer in any tournament -- bettors have gravitated to Phil Mickelson who was once as high as 30/1 odds (Bet $100 to win $3,000), but the three-time Masters champ is down to 15/1 and will likely be dropping even further.

"He's our biggest risk so far," Sherman said of Mickelson. "He's had a good start to the year, and always been supported well in the majors. We have double the tickets written on him than we do on Jordan Spieth."

Spieth won last year's Masters by jumping out to a huge lead shooting a 64 on Thursday and followed it up with a 66 on Friday. Sherman opened him as the the 5/1 favorite when odds were first posted in August after the PGA Championship -- Where Spieth finished second. If Spieth wins again, he'll be the fourth player in Masters history to capture back-to-back green jackets.

"If you look at the top-10 guys on the odds list, they're all in such good form and the people are familiar with them," said Sherman who is considered the top golf oddsmaker in town. "Right now, I think the list of candidates to win is actually a little deeper."

Sherman likes Jason Day's chances a lot this week and currently has him the 7/1 favorite with both Spieth and Rory McIlroy next at 8/1.

He posted a prop on Monday night asking whether any one of the of them would win with NO -240 and the YES at +200.

Another one of his dozens of Masters props is an OVER-UNDER on the best round set at 65.5.

With two full days of action still to go, the SuperBook has already taken quite a few sizable bets on the odds to win board.

"We took a $9,000 wager on Spieth at 5/1 in January, and the second largest was on McIlroy for $5,000," said Sherman, which shows just how large their overall futures pool is that risk on other golfers has allowed the SuperBook to raise the odds on both those golfers despite those large wagers.
