Australian Jason Day has claimed a two-shot lead going into the final round of the Wells Fargo Championship at Quail Hollow.
Day is now 1.75 to win the tournament after he hit a four-under-par 67 in the third round to move onto 10-under par.
He is now two ahead of American Nick Watney thanks to a late surge on Saturday.
Day had started one behind overnight leader Peter Malnati but he birdied the ninth and tenth, and then made further gains at the 12th, 14th and 15th holes.
Day flirted with the water on the 18th but he did enough to par the hole and he was happy with his round after a tough first eight holes.
He told Sky Sports: “Today was a bit of a struggle through eight holes. Didn’t quite get the ball in position.
Got a tap-in birdie on nine and a good shot down the middle on 10. I knew good things would come. I just had to be patient.
“If I can hit a lot more greens and get the proximity closer, I feel like I could, not run away from it, but do pretty well if I can make the putts.”
Watney will be hoping to secure his first win since 2012 and he is priced at 9.50 to do so.
Fellow American Peter Uihlein moved up 45 places thanks to a round of 62 and he is now tied third alongside Bryson DeChambeau, Paul Casey and Aaron Wise.
