After 284 attempts, McEvoy finally got his hands on a trophy but the behaviour of American star and playing partner Bryson DeChambeau overshadowed what should have been a special moment.
DeChambeau had led or co-led the tournament since the opening round but endured an epic meltdown over the closing stages to throw it away, back to back bogeys at the 15th and 16thholes only overshadowed by a heartbreaking triple bogey at the last.
But while understandably upset with his play over the final stretch it was DeChambeau’s apparent snubbing of McEvoy on the 18thgreen which riled fans on social media.
The TV coverage showed DeChambeau offering a very brief and limp handshake to McEvoy who was clearly ecstatic having just made a birdie at the last to win by one.
DeChambeau, the reigning Memorial champion who is rarely far from the spotlight, came in for a mauling on Twitter with most fans unimpressed with his 72ndgreen effort.
It was an unfortunate end to what had been an entertaining week of golf with DeChambeau and Masters champion Patrick Reed among those to put on an otherwise splendid display of golf.
Reed had entered the final round one behind DeChambeau and McEvoy and while he fell away early in the final round the closing stages of the tournament didn’t lack excitement.

Reinstated German amateur Allen John, who is deaf, had set the clubhouse target at 10-under with a stirring Sunday 67 and both DeChambeau and McEvoy were battling to stay ahead.
McEvoy made the turn two ahead but dropped shots at 12 and 13 to hand the lead back to the American.
Two others joined Allen in the clubhouse at 10-under and by the time the final pair arrived at the 18th the Englishman knew he needed a birdie to win or a par to force extra holes.
He ultimately holed a 20 foot birdie to close it out and while fans were less than impressed with DeChambeau’s behaviour it coudn’t have been further from McEvoy’s mind.
“It's incredible,” he said bluntly after holing out.
“I've waited a long time, 17 years as a pro on and off the Tour. I'm absolutely over the moon.
“A lot of hard work, a lot of bad years, a lot of good years but it's never quite happened and it was my time on that 18th green today.
“I fought hard, I believed, and even at the last I overpowered my caddie to lay it up to give myself the best opportunity to make birdie and I managed to do it.”
Scott Hend finished best of the Australians at T13 after a closing 75 while Lucas Herbert made an impressive final round charge to move 32 places up the standings and finish T29 with a 4-under 68.
Andrew Dodt was the only other Australian to make the cut and finished T54 at 1-over for the week.
