Jhonattan Vegas on the cusp of ending seven-year PGA Tour win drought

The Venezuelan, whose last victory came on this weekend in 2017 at the Canadian Open, birdied six of his last eight holes to add to the two shots he picked up on the front nine and post a 15-under total.

On a day of low scoring, four of the top five carded 63s, including 46-year-old Matt Kuchar, who played his final 14 holes in nine under to move into second place in the penultimate event of the regular season.

Maverick McNealy, looking for his first win, is in third to boost his chances of making the FedEx Cup play-offs starting next month, while Patrick Fishburn, the fourth player to shoot 63, is joint-fourth with Sahith Theegala (66) on 12 under.

England‘s Matt Wallace, who only made the cut by a shot, charged through the field to give himself an outside chance of a second PGA Tour win of the season.

The 34-year-old Londoner has had a disappointing few weeks with missed cuts at the Rocket Mortgage Classic and Scottish Open followed by a 41st-place finish at last week‘s Open.

Starting the day three under par he began with three birdies in his first six holes and, after bouncing back from his only bogey at the 11th with an eagle at the next, he closed with three birdies in his last four holes for a round of 64, with his 10-under total pushing him into a share of ninth.

Overnight leader Taylor Pendrith did briefly extend his two-stroke lead but three bogeys and a double in five holes from the seventh and a 73 dropped him to ten under .
