"When we got to the green I looked down and I don't even know what I felt -- I was dumbfounded," Wills told BBC Sport about recording his third ace of the round. "I don't know if I broke out in joy such was the disbelief. It was unreal. I had never experienced anything like that before."
The odds of making three 1's in a single round are astronomical -- "well into the billions," reported BBC Sport.
Laurel Hill golf director Gene Orrico verified the scorecard.
"I was shocked," Orrico said. "I have been around golf for a long time, read the stories, and to have three [holes-in-one] in one round is incredible. Patrick has been around a long time, he is an honourable man and well respected."
The 57 on the par-71 layout was the middle round, one of three 18s played on the same day. In the first round Wills scraped it around in 68. (Ha ha.) He closed with a 66 for a 14-under total and his 20th victory in the Summer Solstice tournament. He is a plus-4 handicap who has now recorded more than 20 aces, all in tournaments.
BBC Sport has a detailed writeup of Wills' 57.
