Five years after his first career PGA Tour win on the very same course, Rory McIlroy dominated the field for his second Wells Fargo Championship victory, becoming the first player to ever win the event twice.
“I’m playing well and I’m really happy with my game,” McIlroy said.
The Northern Irish world number one, 26, finished on 21 under par with a final round 69 in North Carolina to earn his second win at Quail Hollow.
America's Patrick Rodgers and Webb Simpson tied for a distant second on 14 under.
"Everything is firing on all cylinders for me," said McIlroy. "I'm a more controlled player these days. I've learned how to finish things off."
He added: "I felt if I made six birdies there was no chance of anybody catching me.
"I did what I wanted the last few weeks, got a couple of wins, got myself up the Fedex Cup standings and solidified my positions in the rankings."
A bogey at the par-three second, where he three-putted, was his first blemish since the first round but he made the turn at 19 under.
He held form to ease past the previous tournament record of 16 under set by Anthony Kim in 2008.
Averaging 321 yards off the tee, McIlroy tore the course apart over four days – including a third-round 61 during which he only hit more than 9-iron approaches on the long par 3s, on a course that's 7,500 yards long.
The win is McIlroy’s 11th on the PGA Tour, with his 10th coming just two weeks ago at the WGC-Cadillac Match Play. It also marks his fifth top-10 finish in just seven starts this season.
In this kind of scintillating form, McIlroy will fancy his chances of a successful BMW Championship at Wentworth this week.
