WASHINGTON (AFP) — Rory McIlroy delivered a blistering back-nine performance as he powered to victory at the PGA Tour’s Wells Fargo Championship at Quail Hollow on Sunday with a final round six-under 65.

McIlroy had begun the day a shot behind Xander Schauffele and trailed him by two strokes after the American made an eagle on the seventh.

But from then on the world number two was sensational as he left Schauffele in his trail, playing the next eight holes at eight-under, including a pair of eagles.

“I just went on a run that, for whatever reason, I’m able to go on with this golf course,” said McIlroy after his fourth win at Quail Hollow, where he enjoyed the first of his 26 PGA Tour victories as a 20-year-old back in 2010. 

The round was only slightly blemished by a double bogey on the 18th, where he found the water beyond the green but the Northern Irishman’s total was still the lowest round of the day.

After his win at the Zurich Classic of New Orleans team event last month, with Shane Lowry, McIlroy now heads into the second major of the season, the PGA Championship at Valhalla with back-to-back wins.

McIlroy has not won a major since capturing his fourth at Valhalla 10 years ago but he is now in buoyant mood.

“My golf swing feels a lot more comfortable than it has done, so going to the venue next week where I’ve won, it feels like the stars are aligning a little bit,” the 35-year-old said.

“But I’ve got a lot of golf to play and a lot of great players to try to beat next week but I’m going into the next major of the year feeling really good about myself.”

He had begun his round with a birdie on the opening hole and followed it up with another on the fourth but there was little sign of what was to come.

After Schauffele made a tricky 12-foot downhill putt on  the par-5 seventh for eagle, McIlroy missed his 10-footer for birdie and fell two behind.

Schauffele must have felt that was a potential momentum shift in their tight battle and it proved to be — but not in the way the American hoped.

McIlroy birdied the next two holes, while Schauffele could only make par and then on the 10th the Northern Irishman’s brilliant 34-foot putt earned him an eagle.

Schauffele missed his eagle putt, losing his lead with a birdie and it was an advantage he was never to regain as he bogeyed at 12, 13 and 16.
