British Open odds have been posted with Rory McIlroy leapfrogging Jordan Spieth as the favorite. Spieth was actually the one to beat on the opening line, but sharp money propelled McIlroy. Either way at +605 and +690 respectively, both barely edge out Jason Day +700.
The three are the undisputed top contenders as Dustin Fowler is next at +1,4000 with Rickie Fowler, Justin Rose, Adam Scott, and Henrik Stenson as others among the favorites. Grandmaster Sports Handicapper Joe Duffy breaks down all the long shots and betting lines. Odds are based on $100 per wager.
