US Open champion Brooks Koepka will take a two-shot lead into the final round of the US PGA Championship at Bellerive.
Koepka's advantage could have been even greater, only for two late bogeys on day three to give Australia's Adam Scott the chance to close in.
A four-under 66 still keeps Koepka in a strong position, however, with three others - Rickie Fowler, Jon Rahm and overnight leader Gary Woodland - three shots further back as they all chase a maiden major victory.
Woodland had a disappointing round, with a triple bogey on the 10th seeing him relinquish his place at the top of the leaderboard.
Elsewhere, Tiger Woods is still in outside contention thanks to a round of 66 to end on eight-under, while a contingent of four Englishmen are down in joint-21st on five-under.
