( CNN ) -- Rory McIlroy and Luke Donald look set to fight it out for the $ 8million prize at the World Tour Championship after finishing level at the top of the leaderboard Friday . The pair , who are joined on 11-under by Scotland 's world No.189 Marc Warren , are in pole position after another impressive day on the Earth course . World no.1 McIlroy , who revealed that he had been suffering with the extreme heat , looked in top form with tennis ace girlfriend Caroline Wozniacki smiling on from the gallery . Top two dominate in Dubai . `` I did n't feel great last night , but I felt much better this morning and felt nearly 100 % on the golf course , '' McIlroy told reporters . `` I guess it 's just us Irish and the skin just not used to this sort of sun . That 's my excuse anyway . `` I played well . I continued to drive the ball really well and gave myself plenty of opportunities . It was a solid round and obviously , puts me in a good position going into the weekend . `` I am as motivated as I have been the whole year and I am not going to let it drop just for this week . '' McIlroy clinches money list double . It was another successful day for Englishman Donald , who hit a bogey-free round of 68 with two birdies on either half of the course . `` I have n't dropped a shot in 36 holes , so that feels really good , '' he said . `` But it was n't quite as good on the greens today ... I had some opportunities on a few holes that I just misread . '' While the world 's top two have dominated , the emergence of Warren has come of something of a surprise , not least to the man himself . `` It was nice to be the Scot in that pack with the Englishman and the Northern Irishman , '' said Warren , who is ranked 55th in the Race to Dubai . `` It 's great to be in contention with guys like that . I just looked at the leaderboard and kind of enjoyed it really . `` At the same time , I am just trying to stay patient and keep doing what I am doing . I am really looking forward to the weekend . '' While the top three stole the headlines , it was Spain 's Sergio Garcia who carded the round of the day after equalling the course record of eight-under 64 . Elsewhere , South African pair Louis Oosthuizen ( 67 ) and Branden Grace ( 65 ) sit a shot off the lead with Masters champion Charl Schwartzel ( 67 ) and Scotsman Richie Ramsay ( 68 ) tied for sixth at nine-under par .
