Jason Day clawed his way back up the leaderboard to make a solid start to the US PGA Championship in North Carolina.
The Australian world No.7 carded a one-under-par 70 at Quail Hollow on Thursday to sit three shots back of clubhouse leader Thorbjorn Olesen and American Kevin Kisner.
Denmark's Olesen, who won the golf World Cup in Melbourne last year, shot an impressive 67 to take a share of the lead at four-under with Kisner.
Reigning US Open champion Brooks Koepka, Grayson Murray, Chris Stroud, Gary Woodland and DA Points (all 68) share third at three-under.
World No.10 Rickie Fowler, Paul Casey and Patrick Reed (69) headline a seven-way tie for eighth at two-under.
Day, who won the PGA Championship in 2015 and finished runner-up last year, struggled early with three dropped shots through 13 holes before rallying with two birdies and an eagle.
In a share of 15th alongside playing partner and world No.1 Dustin Johnson, the 29-year-old Day leads the Australian charge, with Adam Scott a shot back from his compatriot after carding a respectable even-par 71.
Townsville native Scott Hend is next best of the Australians at one-over after shooting a 72 to share 33rd place alongside world No.2 Jordan Spieth and No.4 Rory McIlroy.
Victoria's Marc Leishman shot a disappointing 75 and is tied for 82nd place alongside Brisbane youngster Cameron Smith, with Queensland veteran Rod Pampling two shots further back after a 77.
Brisbane teaching pro Stuart Deane, who won $US1 million off Donald Trump at an exhibition tournament in 2006, had a shocking 84 to sit last at 13-over the card.
