Day in command of his game and PGA event

World No.12 Jason Day is on target for his second PGA Tour win of the year

Quail Hollow was softer and shorter, producing one low score after another before the final groups even started their final round in the PGA Tour's Wells Fargo Championship.

Jason Day wasn't paying attention, which probably helped, as he aims to seal a second title in 2018.

When he sputtered at the start, there was no reason to panic and when he finally picked up his first birdie by blasting a nine-iron out of the rough with the wind at his back from 195 yards to 18 inches on the ninth hole, he was on his way.

The former world No.1 Day made five birdies over his last 10 holes for a 4-under 67, giving him a two-shot lead as he goes for his second PGA Tour victory this year.

"I was just staying in my own world, staying in my lane and not really thinking about it too much," Day said.

"I knew that if I could just get myself in position ... don't do anything too silly out there and find a way to get back into the swing of things, that I could come out of this on the better half."

Day finished with a daring play on the 18th. With his bare feet in the stream and the ball on the bank well above his feet, he hit a full wedge to the back of the green for a two-putt par.

He was at 10-under 203.

Nick Watney signed for a 66 to be eight under and he will be in the final group for the first time in nearly four years.

Peter Uihlein finished the front nine with five straight birdies and started the back nine with an eagle on his way to a 62, one off Rory McIlroy's course record.

Phil Mickelson shot a 64, his best score of the year to start Sunday four shots out of the lead.

McIlroy three-putted the last hole but still shot 66.

"I didn't play that well. The score sort of flatters me," he said.

Tiger Woods finally got going on the back nine with three straight birdies but a three-putt bogey on the final hole gave him a 68 to be nine shots behind.

Day is in charge but not in the clear with Uihlein, Bryson DeChambeau (66), Paul Casey (69) and Aaron Wise (70) all at seven under.

"I'm driving it better than I ever have before in my career," the 30-year-old Day said.

"I'm No.1 in putting and my short game has come back nicely."
