Jason Day sputtered at the start and hit his stride on the back nine for a four-under 67 to build a two-shot lead going into the final round of the PGA Tour's Wells Fargo Championship.
The Australian former world No.1 did what he had to on Saturday with five birdies in his last 10 holes and a daring shot on the 18th when he stood barefoot in the creek to play a shot onto the green.
Day was at 10 under and is on target for a second victory this year.
Nick Watney carded a 66 to be alone in second at eight under.
Peter Uihlein fired a sizzling nine-under 62 to be among the chasing pack tied for third.
He was joined at at seven under by Bryson DeChambeau (66), Aaron Wise (70) and Paul Casey (69).
Phil Mickelson shot a 64 to move up to 10th while Tiger Woods had a 68 at Quail Hollow to be tied for 31st at one under.
Veteran Australian Greg Chalmers (70) is at two under in a tie for 25th.
