Spieth, of course, has already claimed the first two majors of the season – the Masters and U.S. Open. A prop at the Westgate lists him at 9-to-4 odds to win exactly one more major this year, and 20-to-1 to complete the true Grand Slam by finishing first at the Open and PGA Championships.

Spieth is followed on the British Open oddsboard by Dustin Johnson at 12-to-1, then Justin Rose and Rickie Fowler – fresh off a Scottish Open victory – each at 15-to-1.
Among our other favorite golfers to keep our eyes on, Tiger Woods begins the week at 25-to-1 to break his majors slump, and Phil Mickelson is 30-to-1.
The British Open tees off Thursday at the Old Course at St. Andrews in Scotland.
