Video: American heckler takes up European team challenge and wins in style
Justin Rose was unbeaten in the last Ryder Cup at Gleneagles, but the Olympic champion has already tasted defeat at Hazeltine - to an American spectator.
After Andy Sullivan and Rory McIlroy had failed to make a putt on the eighth green during Thursday's practice round, David Johnson from North Dakota shouted that he could make it from around 12 feet.
Rose and Henrik Stenson, the other two European players in the group, decided to call the man's bluff and brought him out of the crowd, with Rose even betting him 100 US dollars that he would miss.
However, after Rose placed the 100 dollar bill on the green, Johnson promptly holed the putt to spark wild celebrations and earn himself high-fives and hugs from the European quartet.
Stenson said: "We played a match against Andy and Rory and they had a putt and Andy didn't make it, and they tried again to get the right line.
"Someone in the crowd yelled I could have made that, so we let him have a go. All credit to him. Rosie put 100 dollars down and the guy drilled it in the centre.
"He would have been chipping if it didn't go in, but all credit to him for making it."
Rose added: "I thought it (the money) might make it a bit more real for him, but clearly not. The boys were cupping out, missing it low and this guy just got the ball out and ripped it into the middle. Fair play to him and he celebrated in style.
"It's fun. We are doing what we should be doing out here, having fun. We are preparing, we are focusing, but you have to enjoy it."
