US Open Betting Preview: Day Favorite Ahead of McIlroy and Spieth on Odds Board

Rory McIlroy finished with the lowest four-round score of all time at the U.S. Open five years ago when he shot a 16-under 268 at Congressional Country Club. Jason Day finished second that year, eight strokes behind McIlroy.

Day and McIlroy opened as 7-1 co-favorites to win the U.S. Open this week at Oakmont Country Club at sportsbooks monitored by Odds Shark, though oddsmakers have since given Day a 13-2 edge and bumped McIlroy's odds of winning back to 15-2.

Defending U.S. Open champion Jordan Spieth shot a five-under 275 a year ago at Chambers Bay to edge Dustin Johnson and Louis Oosthuizen by one stroke. Spieth is listed as the 17-2 third choice behind Day and McIlroy, while Johnson is fourth at 12-1.

Oosthuizen, the 2010 British Open champ, is further down the betting board at 70-1.

Day has twice finished second at the U.S. Open and is currently ranked first on this year’s PGA money list with more than $5.6 million.

Spieth is ranked third on the money list with just over $4 million, while Adam Scott is second with nearly $4.7 million. Scott is an intriguing value play at 30-1 after finishing in a tie for fourth place last year, which ranks as his best finish ever in the event.

Following a disappointing 10th-place finish at the Masters in April, Day is hoping to build on his title at The Players Championship a month ago. He earned nearly $1.9 million after shooting a 15-under 273 at TPC Sawgrass and previously won the WGC-Dell Match Play and Arnold Palmer Invitational events in March.

McIlroy tied with Day for 10th at the Masters and has not finished better than third in any PGA Tour event in 2016. McIlroy is coming off a fourth-place finish at the Memorial Tournament the first week of June, and he won the Irish Open on the European Tour at the end of May.

Spieth finished 57th at the Memorial after winning the Dean & DeLuca Invitational in the final week of May. His performances have been up-and-down in the four tournaments he has entered since the Masters, when he blew a five-shot lead on the back nine during the final round to finish in a tie for second.

Spieth missed the cut at The Players Championship and then finished 18th at the Byron Nelson before taking the Dean & DeLuca title.
