DUSTIN JOHNSON CHARGED into a handsome six-shot lead at the $9.75 million WGC-HSBC Champions in Shanghai on Saturday after an anticipated battle with close friend Brooks Koepka failed to materialise.
Paul Dunne, meanwhile, continued his rich vein of form to bounce back from yesterdayโs 73 with a two-under par third round to sit in a tie for 12th, 11 shots off the lead.
In breezy conditions Johnsonโs four-under-par 68 stretched his one-shot overnight lead on his fellow American, who shot an error-strewn 73, leaving the world number one in pole position for the final day on Sunday.
Third at Sheshan International Golf Club, on 206 overall and seven shots off the imperious Johnson, was last yearโs runner-up Henrik Stenson of Sweden.
The American Brian Harman and Englishman Justin Rose, the Rio 2016 Olympic champion, were joint fourth.
Johnson and Koepka live near one another in Florida and are fishing and gym buddies.
But the niceties were left in the clubhouse and reigning US Open champion Koepka was immediately on the front foot, grabbing a birdie at the first while Johnson carded just his third bogey of the week.
That immediately wiped out Johnsonโs slender overnight lead and was the first of three birdies on the spin for the 27-year-old Koepka to propel him briefly into the lead.
But that was as good as it got for Koepka.
Johnson made birdies at holes two, four, seven and then at eight, where Koepkaโs challenge faltered badly with a horror triple bogey.
The 33-year-old Johnson, the 2013 Shanghai champion and 2016 US Open winner, made the turn having opened up a four-shot lead on his rival.
Johnson gave a subtle shake of the head after a double bogey at the par-four 10th, but Koepka failed to capitalise with a bogey of his own and Johnson was always in control after that despite the tricky wind.
Hideki Matsuyama, the reigning champion from Japan, had another poor day with a 72 to leave him firmly out of the reckoning.
Meanwhile, Irelandโs Seamus Power is just two shots off the lead at the Sanderson Farms Championship with play suspended during the third round.
The Waterford native carded five birdies to head into the weekend well in contention for his first PGA Tour victory. Americaโs Ryan Armour is currently setting the pace.
