Dufner’s record-breaking 63 had put him two ahead after Day Two, but Furyk’s two-under 68 gave him three shots on Dufner’s 71, with the 43-year-old finishing the day on nine under.
But, on another gripping day in upstate New York, there are a number of sub-plots forming that look like producing a thrilling finale to the final major of the year.
The leaderboard has an air of Smorgasboard in third and fourth place as Swedish pair Henrik Stenson (3/1) and Jonas Blixt (14/1) take up the chase, with both bidding to become the first Swede to win a major.
Look a little further down and there’s real intrigue closer to home too. Lee Westwood made up 15 places with a round of two under making up for some of the mistakes made during his four over second round, and few would begrudge the 40-year-old from Worksop his first major here following successive near-misses.
And near misses seem to be the running theme throughout the top half of the leaderboard, with only McIlroy and Aussie Adam Scott (7/1) joining leader Furyk of those in the top ten with a major to their name.
Few will forget Dufner blowing a five-shot lead and losing a play-off in this tournament in 2011, while Stenson finished second behind Phil Mickelson at this year’s British Open.
Steve Stricker (12/1), tied fifth with Scott on five under, is another who’s best memory of the USPGA is as runner-up, in 1998, while even leader Furyk might be forgiven for thinking more of his recent failures – he lead at this stage four times in 2012 and failed to win any – than his US Open win back in 2003.
It leaves last year’s overwhelming winner Rory McIlroy a very tempting punt at 20/1. With two majors to his name already, there’s no doubting he has the temperament, and after a round of 67 put him straight into contention six shots off the lead at three under, it looks like he’s rediscovered his form too.
With a scorecard that read five over after 11 holes in the second round and looking ready to be swallowed by the cut, it represents a remarkable turnaround for the Northern Irishman.
Last year in South Carolina, McIlroy won at a canter by an astonishing eight strokes, and while there’s no way he’ll repeat that feat this time round, having played his last 25 holes in six under, he’s in a similar confident mood. Should those at the top of the leaderboard begin to choke again, Rory is primed to take advantage.
