The Phoenix Open is always known for being a bit rowdy, but one over-exuberant fan made sure she brought the raunchy to this year's edition.
Fast-finishing Webb Simpson denied Tony Finau a long-awaited second tour victory after after beating him in a sudden-death playoff to clinch the title in Arizona.
However, it was a flashing fan perched in the notorious 16th green grandstand that left a lasting mark on social media - was well as a couple of suspecting golfers.
The 16th at the TPC Scottsdale course in Phoenix has forged a well known reputation in golfing circles as being the "party hole".
The par-three 16th is the only fully-enclosed golf hole on the PGA Tour, with a vast grandstand wrapping around the perimeter.
It’s one of the noisiest holes at any golf course around the world and one of the few places where outlandish behaviour is encouraged, rather than censored.
Needless to say the tournament has seen its fair share of antics, however, one female fan decided to try and up the ante this year.
Footage taken from a smart phone shows the woman leaning over the grandstand rail, shouting at players on the putting green below as she pulls her top down to expose her breasts.
Spectators seated around her could be seen laughing as the camera panned down to the players on the green.
They too couldn't resist having a chuckle as the risqué distraction seemed to hold up play momentarily.
One fan could be heard yelling from the crowd, “He’s dying, he’s dying. He is supposed to putt.”
He later joked that it was no wonder the player in question missed his putt.
Simpson storms home to win in play-off
2012 US Open champion Simpson (69) made clutch birdies on each of the last two holes to catch overnight leader Finau (70) at 17-under 267, then birdied the first extra hole with a 10-foot putt to secure his sixth US tour title.
Finau has played on American Ryder Cup and Presidents teams but has not been able to win since the 2016 Puerto Rico Open almost four years ago.
He also lost a playoff to Xander Schauffele in November 2018 in China at the WGC-HSBC Champions.
"It's hard. He is a great friend," Simpson said. "Our wives are friends and he's one of the best guys on tour. So it is a bit tough."
Finau made par at the last two holes in regulation where Simpson charged, then missed his 18-foot birdie try at the first playoff hole.
He was philosophical in defeat.
"If you are going to get beat, that's how it should happen," Finau said.
"I definitely didn't give him the tournament. Unfortunately, it's how the cookie crumbles.
"I love Webb. I think the camaraderie that I have with him as being one of my best friends out here, it would have been hard for either one of us to take this victory from each other."
Simpson improved his poor playoff record to 2-6, three years after falling to Hideki Matsuyama in extra holes at TPC Scottsdale.
