Ernie Els took notice of what MCI Classic expert Davis Love did on the first two days to take a two-stroke lead over Steve Lowery.
Els carded a 5-under par 66 in his third round and moved into position for Sunday, ahead of Love who drifted away from Els on moving day.
But Love still managed to keep within firing range with a one under par 70 thanks to two tap in birdies at 17 and 18, but it is Els who has worked the hardest around the narrow treelined course in South Carolina.
"I think I've put the work in and it's time, I guess, for it to pay off," said Els
"I feel like my game's a lot closer than it seems."
Els is looking for his first victory since last years Nissan Open at the Riviera Golf Course in Los Angeles and will be keen to get back to winning ways before the US Open at Pebble Beach.
But before he can claim victory at the MCI, he still has to battle out with Steve Lowery and of course, Davis Love the Harbour town expert.
"I got myself back in it," Love said. "But I just got caught behind a guy who was playing so well."
Els wasn't the only one who played well. Some did even better and closed the gap at the top. Lowery had a 66 to stay right where he want to be, Scott Hoch shot a 64, Larry Mize had a 65, his lowest round here in six years and Chris Perry tied the back nine record of 29 for his 65. And there was a glint of the former greatness from Curtis Strange, normally to be found in the commentary box for the television, he shot a 65.
