Three players are tied for first place after Friday&aposs second round of the DP World Tour Championship in Dubai. World No.1 Rory McIlroy and Scotland&aposs Marc Warren both scored five-under-par 67 to join first-round leader Luke Donald at the top of the leaderboard at the Jumeirah Golf Estates. McIlroy started his round strongly with birdies on the 2nd and 3rd holes before bogeying the 4th. The Northern Irishman fought back to score birdies on the 7th, 10th, 15th and 16th holes to remain well in contention for the major honour. Warren had a similar round to McIlroy, shooting three birdies and a bogey on the front nine before holing three birdies on the way in. However, the Scot missed a golden opportunity to take the outright clubhouse lead on the 18th when his birdie just missed the target. After a bogey-free opening round, Donald again repeated the dose with a consistent four-under-par 68. The Englishman needed a birdie on the 18th and he responded with a magnificent approach shot on to the green that allowed him to rejoin the leaders. South African duo Branden Grace and Louis Oosthuizen tied for fourth after recording rounds of 65 and 67 respectively. Grace&aposs seven-under-par round began with three consecutive birdies. The round of the day went to the Spanish star Sergio Garcia who scored an incredible eight-under-par 64 that included a triple bogey and two bogeys but was offset by two eagles and nine birdies. Despite his low score, Garcia still remains four shots off the pace after an opening round 73. Australian Marcus Fraser had a five-under-par 67 to trail the leaders by three shots.
