US Open 2015: Betting Odds For Rory McIlroy, Phil Mickelson, Tiger Woods And More For Golf Major

Less then two months removed from his first major victory, American Jordan Spieth joins Rory McIlroy as the favorites to win the 115th U.S. Open, beginning Thursday at Chambers Bay Golf Course in University Place, Washington.

McIlroy is listed at 7/1, and the 21-year-old Spieth is just behind at 8/1 odds, according to Bovada.lv, which puts the darling Masters champion in line to capture golf’s second major of the year. A prop bet also puts the chances of McIlory, Spieth, Justin Rose, and Dustin Johnson at +180, and the field at -240.

Spieth finished 18-under at Augusta earlier this year, and though he’s yet to win another tournament since, he’s tops in the game in money earned and in the FedEx Cup standings.

And the sport’s budding star appears confident, even contemplating a potential Grand Slam.

"You can't win a Grand Slam unless you win the first," Spieth said to Fox Sports. "So I'm the only one with that opportunity this year. I'm going to go ahead and focus on this week and see if I can put myself in contention."

But Spieth does face a mix of veterans and previous U.S. Open champs, including McIlroy. The 26-year-old launched to stardom back in 2011 to win the tournament by eight strokes ahead of runner-up Jason Day.

McIlroy also finished fourth at the Masters this year, his best showing at the event in his career. And unlike Spieth, he’s won two tournaments since, and wound up eighth at The Players Championship last month. Spieth actually missed the cut at that event, firing off eight bogeys over two rounds.

After the two favorites comes perennial runner-up threat and American Phil Mickelson at 16/1. He’s claimed all of golf’s majors except for the U.S. Open, tying or outright claiming second place six times over this career.

And three-time U.S. Open champ Tiger Woods finds himself square in the middle of the pack at 50/1. The last major Woods won was the U.S. back in 2008 after a playoff with fellow American Rocco Mediate.

Ever since Woods’ troubles on the course have been well documented, including his most recent flub at the Memorial two weeks ago. In the worst round of his career, Woods fired off an 85 in the third round on the par-72 course and finished 14-over in the tournament.
