Henrik Stenson's form showed no sign of relenting as the Swede, hoping to create history by becoming the first player to win the FedEx Cup on the PGA Tour and Race to Dubai crown on the European Tour, took a one-shot lead at the halfway stage of the $US8 million ($A8.60 million) DP World Tour Championship.
At the Earth course of Jumeirah Golf Estates, Stenson never looked in any trouble as he put together a stunning, bogey-free round of eight-under par 64 - the joint best round of the day.
That gave the 37-year-old a two-day tally of 12-under par 132, one better than overnight leader, Spain's Alezandro Canizares, who added a bogey-free 67 to his overnight 66.
Last week's Turkish Open champion, France's Victor Dubuisson, moved into contention again with a 66 that took him to tied third place at eight-under par 136 alongside Australian Marcus Fraser (69).
Among those who can deny Stenson the honour of becoming the European number one by winning this week, No.2 in the Race to Dubai standings, Justin Rose (67), and number four Ian Poulter (68) were tied for fourth place at seven-under par 137 alongside Thai Kiradech Aphibarnrat (70).
No.3 Graeme McDowell started the day with a bogey, but then regrouped with five birdies to finish with a four-under par 68 round.
Also moving in the right direction was the defending champion Rory McIlroy. The former world No.1 shot a five-under par 67 round to move up to tied ninth place at six-under par, six shots behind leader Stenson.
Stenson, who is playing with an injured right wrist, said he feared he had seriously injured his hand after coming down too steep on the ball on the sixth hole. But luckily for Stenson, and unluckily for the field, the wrist withstood the blow.
After the round, in which he hit 17 greens in regulation for the second successive day, Stenson said: "I'm just trying my best to carry on the momentum.
"I was playing nicely yesterday and had a lot of chances. Didn't take them. Today, I was playing the same more or less. I hit a lot of fairways, a lot of greens, gave myself opportunities and rolled a couple of nice putts in.
"I've got my game plan pretty much cemented on what to do on this golf course and where to hit it and I'm just trying to execute as good as I can, and that's been working out great these first two days and making a lot of birdies.
"Of course, it could be a bit better, but there's no point being greedy, either. Everyone is going to miss a few out there on the greens. They are tricky to read and a lot of grain and they are quick."
