Sure enough, David Johnson from North Dakota, wearing jeans and a red shirt, rammed the ball in the back of the cup and celebrated as if he had won the Ryder Cup himself, getting hugs from Rory McIlroy and Henrik Stenson.
"The boys were struggling with their lines, and David was kind enough to come down and show us how to do it," said Stenson, tongue firmly in cheek.
Johnson heckled the European players, saying he could make that putt.
"Somehow, it fell in," said Johnson, who got the currency autographed.
