Rory McIlroy is four shots behind leader Xander Schauffele after the second day at Wells Fargo in Charlotte.
The Northern Irishman shot a faultless 18 holes on Friday at Quail Hollow with three birdies for a three under par 67 to hold his spot in second place, tied with Australian Jason Day.
McIlroy told reporters that he felt like he could have “squeezed a couple more out of the round” but was happy that he went bogey free.
He said: “Another solid day. Felt like I probably could have squeezed a couple more out of the round, but anytime you can go around this golf course bogey free it’s always going to be a decent day. It’s two solid days. I set myself up for another good go at it this weekend.
“I’m comfortable here. I think I can take advantage of how far I hit it off the tee.
“I think this golf course really lends itself to driving distance. So the fact that I’m comfortable, the length off the tee, and then I’ve had so many good memories here, just I feel positive vibes, I feel good about myself when I’m walking around here.”
American Schauffele extended his lead to four strokes, grabbing five birdies and a bogey on the last hole of the day to sit on top with 11 under par.
“Just played some really nice golf the last two days,” said Schauffele. “Really happy to get that last hole in. I know it wasn’t — most of it was pretty until the end there.
“I had some birdie looks and when I was out of position I was able to hit the green still from the rough,
which is a really tough task with the resurfacing of the greens here. Felt like I sort of plotted around the property pretty well.”
Day sits tied with McIlroy heading into the third round after he shot six birdies and two bogeys.
