Lucas Glover and Billy Horschel share the lead at Wyndham Championship

Glover, the 2009 U.S. Open championship shot an eight-under round of 62, finishing with back-to-back birdies at Sedgefield Country Club.

Horschel shot a bogey 63 while overnight leader Russell Henley slipped back after his 65 which also ended with birdies on the 17th and 18th.

Glover's only blemish came on the eighth hole, where he three-putted but he bounced back immediately with birdies on the 9th and 10th holes.

"I hit it nice, hit every fairway and missed a green. Irons were pretty sharp today, hit it close a bunch and putted nicely," said Glover, who said his approach on Sunday would be to avoid being too adventurous.

"I think you try to attack this place a little too aggressive and miss some fairways, it can bite you. I learned that quite a while ago," he said.

"I think it's just a 'fairways first' mentality and then if you get some good numbers and hit it close, you've got a good chance to make some birdies," added Glover.

The 43-year-old from Greenville, South Carolina, said he felt at home on the course.

"I've got a lot of family in this area. I've got two or three uncles that were members here years ago and still got a bunch of cousins in the area. We are three hours from where I grew up and I like the course. Just like it. It's a special place," he added.

The 43-year-old Glover will be targeting his fifth win on the PGA Tour with his most recent victory coming at the John Deere Classic two years ago.

Floridian Horschel has seven wins on the PGA Tour already under his belt while Henley is looking to add to his four victories, the last of which came in November 2022 in Los Cabos, Mexico.

Horschel knows he needs a win or a solo second to make into the FedEx Cup playoffs and says he is looking forward to going head-to-head with Glover in the final pairing.

"I've played a lot with Lucas and I've always enjoyed playing with him. He's had his up and downs in the game of golf - no one's ever gone through not having a period of that.

"So it's going to be an amazing round of golf, we're both going to be battling out there. We've got Russell Henley right behind us and a couple of other guys not too far back," he said.

South Korean An Byeong-hun is three strokes off the lead after his 65 while German Stephan Jaeger is a further two shots back after ending with three birdies in a row.
