Scott will be paired with Graeme McDowell on the last day after the Northern Irishman ended the day on seven under par.
Overnight leader Brandt Snedeker struggled on day three, shooting a 73 which included six bogeys.
Tiger Woods is in contention on six under par, the American started badly dropping two shots early on before ending his back nine with three birdies in four holes.
Bubba Watson shot a a solid round of 68 which included six birdies which could have moved him into contention had he not double bogeyed the 15th.
After the round Scott said he was not taking anything for granted.
"A four-shot lead doesn't seem to be very much this year on any golf tournament that I've watched," he said.
"The good part is if I play a solid round of golf tomorrow, it will be very hard for the others to beat me and that's all I'm thinking about."
