Byrd (left) gets his trophy from popstar Timberlake
Jonathan Byrd knocked in a hole-in-one on the fourth play-off hole to beat Scot Martin Laird to the Justin Timberlake PGA Tour event in Las Vegas.
Byrd, defending champion Laird, and Cameron Percy were involved in a three-way play-off as darkness descended.
The trio debated whether to keep playing and, when they did, Byrd holed the 204-yard par-three 17th to earn victory in spectacular style.
"I hit it perfect - for it to go in, that's just luck," said American Byrd.
His shot landed 10 feet short of the cup before finding its way into the hole as Byrd won his first title since July 2007 and the fourth of his career.
"I didn't see it," he stated. "I'm in shock. I think the people at the green were the only people who could see it."
Laird, who had taken a one-shot lead into the final round, and Percy both put their tee shots into the water to confirm the win for Byrd.
"I kept preaching to myself all day, hang in there," commented Byrd, who earned his play-off place after he birdied three of the last four holes in regulation play.
"What an unbelievable day. It's hard to process because I'm still in shock."
