Rory McIlroy furiously confronted more American Ryder Cup fans on Sunday afternoon, after they used squeaky rubber ducks in a desperate bid to put him off.

The Team Europe superstar has clashed with the rowdy locals across all three days of the tournament, with the anger reaching boiling point on Saturday when he screamed 'f*** you' at multiple fans on the 18th green.

But the frustrations continued into Sunday - and in bizarre fashion - after he was continuously put off by the use of a small plastic toy.

As reported by NBC, fans who bought a 'Cherry Fairway Fizz' drink at Bethpage Black were given a free squeaky duck toy... and Americans made use of them in an unexpected way to disrupt McIlroy's game.

On the 10th tee, McIlroy could be seen asking security to remove some fans after they continued squeaking the ducks while he tried to play his shot. 

After he spoke to officials, McIlroy pushed his drive into the rough, and then lost the hole to allow Scottie Scheffler to go 1UP.

Ryder Cup officials told the Daily Mail that the drinks are no longer being sold, and security are actively on the lookout for the toys and are confiscating them from fans. 

The incident comes 24 hours after he told spectators, 'Guys, shut the f*** up' after they jeered him while he addressed the ball.

A few hours later, it was reported that Erica was in tears coming off the 18th green after the relentless abuse faced by her husband throughout the first two days of competition at the Ryder Cup.

After initially beginning as a humorous atmosphere - McIlroy joked with fans on Thursday during his practice round - Bethpage turned ugly when the tournament got underway.

On Friday evening, McIlroy gave the middle finger to fans as he walked off at the end of one of his rounds, and on Saturday morning he was met with 'f*** you, Rory' chants on the first tee.

Those X-rated chants were led by an American comedian MC'ing the first tee, and she then stepped down from her role ahead of the final day.

Throughout Saturday, McIlroy was subjected to more abuse, snapping during one hole to swear at the fans.

As play continued, extra security was rushed in to protect the group, some fans were ejected from the course, and the chants got more and more vile.

Some jabbed the five-time major winner with comments about his divorce and Amanda Balionis, all with Erica watching on from close by.

As McIlroy walked off the final hole, he pointed at specific fans next to the green and said: 'F*** you, f*** you, f*** you.' 

His wife was then hit by a drink thrown by a fan, with shocking new footage showing McIlroy needing to be held back to stop him from confronting those in question.
