Think Jordan Spieth will win the Grand Slam this year? If you're willing to put down on it, you'll net a healthy return.
Online oddsmaker Bovada has installed the Masters and U.S. Open champion at 25 to 1 to win all four majors this year. If you think he'll walk away from both the Open Championship and the PGA empty-handed, you'll need to wager a sizable amount to generate any worthwhile return at 1 to 4. If you want to split the difference and say he'll win one or the other, you can get in at 11 to 4.
