Adam Scott began the day in third place and one shot out of the lead but as his game deserted him in the middle of his round it was Cameron Smith who found his mojo and began charging up the leaderboard.
Four straight birdies from the fourth to the sixth put Smith in the mix as he went to the turn and he cashed in on the confident start with a 2-under back nine to sign for 65 and an 11-under total.
That’s five behind leader Bryson DeChambeau but only one behind second placed Keegan Bradley, Smith in position to pounce should either of the Americans stumble.
Scott, meanwhile, ended a frustrating round on a high note with a birdie at the last to get within a shot of his countryman and not out of calculations.
Day three was a grind for the 2013 Masters champion who struggled to get any momentum over the first 12 holes.
He turned 1-under with three birdies against two bogeys but a bogey-double bogey run to start the back nine did little for his cause.
To his credit, he knuckled down and managed to make three birdies in his final four holes to get it under par for the day and at 10-under shares fifth place alongside Billy Horschel.
It was a day of battles for several of the game’s big names, Brooks Koepka and Dustin Johnson among them.
Both signed for 1-over rounds of 72, Koepka falling from the top of the leaderboard to a share of seventh and Johnson down 16 places to T20.
The poor scoring from the top echelon was a surprise as low scores were gettable on the Ridgewood Country Club course.
Keegan Bradley posted a 9-under 62 while DeChambeau was around in 63. Jordan Spieth, who has struggled all week, found something Saturday to record a 64 and at T7 is on the edges of contention.
Jason Day hasn’t been at his best this week though at 8-under and T14 is hardly playing poorly.
The same can’t be said for Marc Leishman whose 1-under 70 sees him at the same total for the tournament and T58.
Tiger Woods posted his first sub-par score of the week, a 3-under 68 to be 3-under for the week and T49.
