Swim great Michael Phelps upstaged some of golf's finest when he holed a 51-yard putt for a net hole-in-one during the second round of team play at the Dunhill Links Championship on Friday.
Phelps, who is playing the team event with a 16 handicap, drove the front edge of the green at the par-4 sixth hole at Kingsbarns before sinking his lengthy downhill second-shot putt.
Because the winner of 18 Olympic gold medals had a stroke on the hole, he signed for a 'one' on his scorecard.
"That was the longest putt I've ever holed," he said. "It was pretty incredible, watching it dive in was a pretty cool feeling. So to be able to have a net hole-in-one was pretty special.
"Even without that, this trip would have been very special, just having the opportunity to come over here and play among some of these players has been absolutely incredible."
Phelps recorded a net eagle 'two' at the next with professional partner Paul Casey. They moved to 9-under overall.
Thailand's Thongchai Jaidee and his amateur partner, Hugh Courtney Jr., lead the team format at 21 under.
