US Open Odds 2015: Latest Lines for Top Favorites at Chambers Bay

Despite the public perception, the U.S. Open is the biggest and most important tournament played on American soil all year.

The Masters may get most of the hype, but the U.S. Open is the national championship, and the best golfers in the world are joined by the most deserving qualifying non-touring pros and top amateurs.

The U.S. Open is regularly played at the toughest courses, which are designed to reward golfers who hit the ball accurately and for distance. However, thick rough and difficult hazards punish golfers who don't keep the ball on the fairway.

This year's U.S. Open will take place at Chambers Bay in Washington. This is a new track for the PGA Tour, marking the first time the U.S. Open will be played in the state of Washington. 

Here's a look at the four favorites in the field, according to Vegas Insider.

Rory McIlroy (5-1), is favored to come out on top in the U.S. Open. The No. 1 player in the world won the U.S. Open in 2011 and has won the British Open once and the PGA twice. McIlroy has a lot going for him statistically this season, as he is averaging 305.8 yards off the tee, ranking eighth on the tour. 

McIlroy has gained an average of 2.0 strokes tee to green this year, ranking first on the tour. He also has hit 70.45 percent of his greens in regulation, ranking seventh on the tour.

Jordan Spieth (8-1) will be going after his second major of the year after his dominant victory at the Masters. 

Spieth is the FedEx Cup points leader and is averaging 69.1 strokes per round this season, the best on the tour. Spieth has played 16 events this season and has two victories, three second-place finishes and one third-place. He also has nine top-10 performances.

Spieth has gained an average of 1.6 strokes from tee to green, ranking third on the tour. He has earned more than $6 million in prize money.

Golfer	Odds
Rory McIlroy	5-1
Jordan Spieth	8-1
Phil Mickelson	15-1
Dustin Johnson	18-1
Justin Rose	20-1
Rickie Fowler	20-1
Jason Day	22-1
Adam Scott	25-1
Bubba Watson	30-1
Henrik Stenson	30-1

Phil Mickelson (15-1) has never won the U.S. Open, so this is the tournament he has been shooting for throughout his career. Mickelson is not enjoying his best year, as he has not claimed a victory in any tournament, although he does have second- and third-place finishes.

One of the reasons Lefty has been off his game this year is a lack of accuracy. He has found the fairway just 57 percent of the time, which ranks 153rd. Mickelson is normally one of the best bunker players on the tour, but his sand save percentage is 54.3 percent, which ranks 64th on the tour.

Dustin Johnson (18-1) has played in 13 tour events this year and has one victory to his credit along with a second-place and six top-10 finishes. Johnson has earned nearly $3.5 million this season and is seventh in the FedEx Cup standings.

Johnson is the longest hitter on the tour, as he is averaging 317.6 yards off the tee. He is averaging 69.8 strokes per round, which ranks fifth. He is also averaging 4.35 birdies per round, making him sixth on the tour.
