Day, Johnson Favorites at The Open

By ESPN

Jason Day and Dustin Johnson are favorites this week at The Open, but bettors and bookmakers both abroad and in Nevada agree that the tournament at blustery Royal Troon is wide-open.

Day is the favorite at 7-1 at the Westgate SuperBook. His odds were trimmed from 8-1 to 7-1 after a limit wager (to win $50,000) was placed Tuesday. Two times more money had been bet on Day to win the tournament than any other golfer at the SuperBook, as of Tuesday afternoon.

Johnson, fresh off back-to-back wins, including at the U.S. Open, is the favorite at 13-2 at William Hill's Nevada sportsbook. Johnson had attracted more money than any other golfer at William Hill U.S. and at Ladbrokes' sportsbook in the United Kingdom.

Jordan Spieth and Rory McIlroy are next, both at 10-1 at the SuperBook. McIlroy had attracted less than one-tenth of the money wagered on Day.

Weather is expected to be a major factor this week at Royal Troon, where heavy rain and winds up to 30 mph are expected over the weekend.

"The weather definitely could level the playing field, give more a guys a shot, including some long shots," said Jeff Sherman, assistant manager at the SuperBook and a golf-odds specialist at the Westgate.

Because of the weather forecasts, Sherman bumped up the over/under on the winning score from 273.5 to 274.5.

Several long shots have garnered notable action, including veterans Lee Westwood (50-1) and Jim Furyk (50-1). Only three golfers -- Johnson, Sergio Garcia and Day -- had received more bets at the SuperBook than Westwood, who stayed in contention at the U.S. Open before falling off in the final round.
