The Ryder Cup is known for incredible shots. Chip-ins, eagles, holes-in-one, monster putts, booming drives. We've seen it all over the years - but not quite like this one.
During the early stages of the Saturday afternoon fourballs tie of Rory McIlroy and Thomas Pieters versus Brooks Koepka and Dustin Johnson, the match arrived on the driveable par four fifth, where something extraordinary unfolded.
Not only did Koepka's tee shot land in a spectator's backpack - that certain spectator only turned out to be no other than his opponent Pieters' father Jaak, who was following his son around on a sunny Saturday afternoon at Hazeltine. Watch on...
"I was walking towards the green and my son had already hit his shot and was on the putting surface and then all of a sudden there were shouts that Brooks Koepka's drive was coming my way," Pieters' father Jaak told us afterwards. "So I turned my back and the ball bounced once on the ground and onto the top of my backpack.
"They told me to just stay calm and stand still and don't move so I just stood there and couldn't do anything until they arrived at the green. So Brooks took the ball from my backpack and had to drop it right there. It was pretty crazy - and then to top it off, Thomas made his putt for eagle!"
Making his debut in the biennial clash in Minnesota, Pieters has two wins from as many matches so far and was on course for a third success midway through Saturday afternoon as the 24 year old bids to retain his 100 per cent record alongside former World Number One McIlroy.
His father is clearly a very proud man right now.
"I can't tell you how proud I am, it's hard to describe," he continued. "It's unbelievable. Walking around with him, hearing all the crowd shouting - good and bad! - but he is playing so well, it's amazing to be here and to experience it all."
