According to the Westgate SuperBook, the trio of Dustin Johnson, Rory McIlroy and Jordan Spieth, at 10-1 each, are the favorites to win the U.S. Open being held this year at Shinnecock Hills Golf Club in Southampton, New York.

McIlroy has not won a major since 2014, but a recent run of good golf has him a favorite along with the 2015 winner of the tournament (Spieth) and the 2016 winner (Johnson).

Behind them at 12-1 is Justin Thomas, winner of last season's PGA Championship.

Jason Day has 14-1 odds, and Rickie Fowler and Jon Rahm are at 16-1. Fowler, who is still looking for his first victory in a major, finished a stroke back at the Masters. Rahm finished fourth at Augusta.

While those men were all chasing Reed at the Masters, at 30-1, he finds himself with worse odds to win next month's major. Even Tiger Woods, who has shown a return to form after years lost to injury, is favored ahead of Reed, with 25-1 odds. Woods has won the U.S. Open three times, but it has been 10 years since his last title at the event.

Shinnecock last hosted the U.S. Open in 2004, a tournament won by Retief Goosen. The runner-up that year, Phil Mickelson, has the same odds to win this year's tournament (30-1) as Reed.

All four major titles are currently held by Americans, with Brooks Koepka (40-1) hoping to defend his U.S. Open championship when play starts Thursday, June 14.
