A third round 65 has given Graeme McDowell hope of claiming back-to-back wins for only the second time in his career.
The Northern Irishman, who won the OHL Classic last week, is four shots off the pace in The RSM Classic at Georgia’s Sea Island.
McDowell had birdies at the fourth and ninth holes to go out in 33, before picking up further shots at the 10th, 14th and 15th.
However, Kevin Kisner has the edge heading into Sunday’s final round, as he seeks his first victory on the PGA Tour.
The 31-year-old’s six-under-par total of 64 gives him an overall score of 16 under - and a three-shot lead over fellow American Kevin Chappell.
South Carolina’s Kisner told pgatour.com: “I’ve been striking it nicely all week and continue to give myself a lot of chances for birdie. Today I capitalised on a few of them.
“I hit it close on two out of the last three and made the nice long one on the last hole. Hopefully I can keep it going.”
Germany’s Alex Cejka is a shot adrift of McDowell after a third successive 67, with Americans Jeff Overton and Jim Herman sharing fifth, another shot back.
