Two-ball and three-ball betting is quite similar to head-to-head betting. You are selecting which of two or three golfers will score the lowest for that round. The biggest difference, however, is that the golfers you’re betting in two-ball or three-ball will be playing together as part of the same group. You’re basically betting which golfer will “win” out of a three-person group on the weekdays or a pair on the weekends.
