In the 2026 Open Championship's first round, three golfers compete in a 3-ball grouping: Matthew Southgate, Martin Couvra, and David Duval. The player with the lowest score for the round wins the 3-ball matchup.
The winner of the 3-ball matchup is determined by the lowest score recorded during the first round of the 2026 The Open Championship. If multiple participants finish the round tied for the lowest score, the Yes payout is divided equally among all tied participants, with each receiving $1/N rounded down to the nearest cent, where N equals the number of tied participants; the No payout equals $1 minus the Yes payout. If any golfer withdraws prior to teeing off, all markets resolve to fair market value.
