Justin Rose has lifted the lid on the heated exchange between Team USA and Team Europe in the Ryder Cup on Saturday.
Alongside Tommy Fleetwood, Rose performed spectacularly to extend Europe's historic lead on the day.
However, tensions boiled over after Bryson DeChambeau's flamboyant celebrations were deemed too far.
Both caddies were involved in the spat during the walk between holes.

Rose admitted it was a "shame" that the day was marred by such controversy.
"It was a shame it got to that point as it was a great match," he said.
"I was waiting to putt and the boys were working on their read and their calculations. I waited a few seconds and then they came up again.
"I said 'it was my putt' but maybe I could have said it more politely. By no means was there any disrespect meant. I said if you want me to say 'excuse me please' then my bad.

"I hope it is put to bed. It should be put to bed. There was no intent whatsoever. I admire Scottie more than anyone else on tour. It was something that was taken in a way that wasn't intended.
"I am just trying to control my environment in that moment."
It was a chaotic day at Bethpage Black that saw European golfers face a shocking level of hostility from American spectators, most notably Rory McIlroy and Shane Lowry.

Multiple spectators were thrown out of the venue due to the severity of the abuse, while police officers with dogs had to patrol the course as tensions reached breaking point.
At one stage, McIlroy refused to take his shot until the crowd quietened down. The Northern Irishman stood over his ball for four minutes, stepping away twice as jeers and shouts continued.
The abuse directed at McIlroy and Lowry included insults about their wives, families and physical appearance throughout the afternoon.

Things got so bad that Lowry snapped at one spectator on the third hole, yelling "f*** you" in response to particularly nasty heckling.
He later had to be held back by his caddie on the 10th tee after another confrontation.
The crowd ignored basic golf etiquette, shouting during backswings and just as players were about to hit.
When officials displayed messages warning against abusive behaviour on the big screens, American fans actually booed them.
Even the morning's MC joined in, leading an expletive-filled chant against McIlroy before the first tee shot. She later apologised and stepped down from her duties.

The drama escalated when McIlroy lined up a crucial putt on the sixth green. He stepped away from his ball twice as the hostile crowd refused to settle, making it clear he wouldn't play until they calmed down.
Police had to rush extra officers to their match, with state troopers lining the fairways. One fan was carted away on a buggy after Lowry pointed them out to security.
Even American Justin Thomas tried to calm his home supporters, shaking his head and raising his hands for silence.

The situation became so tense that officers were specifically assigned to follow Bryson DeChambeau's group over fears things might kick off there too.
By late afternoon, a fist fight actually broke out between two spectators in the grandstand behind the 18th green.
Despite the hostility, Europe absolutely dominated on the scoreboard. They ended Saturday with a commanding 11.5-4.5 lead, putting them within three points of their first away victory since 2012.
McIlroy and Lowry eventually won their match, celebrating wildly on the 18th green as European fans finally gave them something positive to hear.
"I'm drained to say the least," McIlroy admitted afterwards, though he praised Lowry for being "there for me all day."
Lowry acknowledged it was "something I've never experienced" but insisted "this is what I live for."
European captain Luke Donald also praised how well his players handled the situation.
The seven-point advantage represents the biggest lead ever going into a Ryder Cup final day.
