Justin Rose shot a six-under-par 64 to take the BMW Championship lead after round three in Philadelphia.
The Englishman is one shot clear of Rory McIlroy, who moved up into a share of second with overnight leader Xander Schauffele after a seven-under-par 63.
Tommy Fleetwood is level with Rickie Fowler one shot further back after scoring an eight-under-par 62 for the second successive round.
Tiger Woods moved up to joint 11th with a four-under-par 66.
"Tomorrow will be gruelling, it's set to rain all day and it will be a battle," Rose told Sky Sports.
"Just getting round will be a win I think, perhaps the weather will help keep me distracted but a one-shot lead with a chasing pack behind doesn't mean much."
