Bryson DeChambeau finished tied for 14th at the 154th Open Championship after a final round of 72 left him at four under par, well short of eventual winner Ryan Fox at Royal Birkdale.
The American, who had accused of "holding the tournament ransom" by Rory McIlroy after receiving a two-shot penalty for stomping down long grass behind his ball, lost his ball on the 11th hole and had to be driven back up the fairway to play another, as chants of "McIlroy, McIlroy, Rory McIlroy" rang out from the crowd.
On the first tee, a spectator shouted "Rory's going to buy you a pint after!" to laughter from the grandstand, after McIlroy stoked the row on Saturday evening over DeChambeau's penalty and his threat to withdraw.
The collapse on 11
DeChambeau opened with eight straight pars before dropping a shot on the ninth. On the 11th, he pulled his tee shot into thick rough and could only advance his second eight yards. His third shot went so deep into the rough beside the green that he could not find the ball and had to return to play another, taking a triple bogey that ended his hopes of a third major title.
A couple of birdies later in the round were not enough to repair the damage. Having missed the cut in all three other majors this year, a tie for 14th was still an improvement, and without the two-shot penalty he would have finished tied for sixth.
McIlroy and Scheffler weigh in
McIlroy had declined to defend DeChambeau after the third round when asked whether he believed DeChambeau knew what he was doing by treading on the grass around his ball on the fifth hole, a action officials ruled had inadvertently improved his swing path. McIlroy said he was not in DeChambeau's mind but that it did not look good.
World number one Scottie Scheffler offered more support, saying DeChambeau was a lot of things but definitely not a cheater, and that he had never seen him cheat, whether in a putting contest or a chipping contest on the practice green.
DeChambeau stays quiet
DeChambeau again refused to give any post-round interviews. Walking past a small group as he left, he told them to have a great night and thanked them, before posing for selfies with fans and a reporter outside the media centre.
