The winner of the British Open at St. Andrews will take the Claret Jug and £1.15 million in winnings…unless that winner is an amateur.
If Paul Dunne, Jordan Niebrugge or any other amateur wins the British Open in surprising fashion, they will not be able to claim any prize money. Instead, they will win the Claret Jug, Gold Medal and Silver Medal (top amateur).
Any prize money they would normally win is instead spread across the rest of the field in tapered fashion. Prize money is issued as if amateurs are not playing, meaning the second-place finisher (if an amateur won) would claim the £1.15 million.
Amateur players are not eligible to win prize money. If an amateur wins #TheOpen, they will receive the Gold Medal and the Claret Jug.

The prize money for first place is increased by £175,000 (18 percent) from 2014. Second and third place will earn £653,000 and £420,000, respectively.
