( CNN ) -- Teenage sensation Matteo Manassero and Spaniard Alvaro Quiros joined world number two Luke Donald at the top of the leaderboard after the second day of the BMW PGA Championship . Donald , from England , was out in front after a sparkling 64 on the opening day but he struggled in calmer conditions on Friday , carding a one-over-par 72 to sit on six-under . Manassero , from Italy , followed his 66 on Thursday with a one-under round while Quiros fired a four-under round of 67 to make it a three-way tie at the top on a day when players , spectators and officials all wore blue in honor of the late Seve Ballesteros . Spaniard Jose Manuel Lara , Thomas Aiken , from South Africa , and England 's David Horsey all sit two shots off the lead on four-under . Donald , who can claim golf 's number one ranking from compatriot Lee Westwood with a win at Wentworth , told the European Tour 's official web site that Manassero 's maturity had made an impact on him . `` I 'm impressed with him in general , '' he said . `` I think to have done as well as he has done at such a young age is very impressive . I suppose he has a somewhat similar game to me -- he does n't overpower courses . '' No-one on the course bettered Quiros ' round of 67 and the Spaniard said his putting was a big factor in his impressive display . `` I 've been playing very , very safe , so I think it 's a good thing , having in consideration the bad weather and the greens , how hard are the greens , they are tough and quick . `` It 's a good strategy , probably is giving me bonuses without hitting the ball great . '' Manassero could n't match the standards he set on Thursday , but said he had been inspired by the crowd of over 25,000 that helped to pay tribute to Ballesteros -- one of the sport 's biggest characters . `` I 'm happy about 70 today -- it was n't easy , '' he said . `` The flags I think were trickier and it was a more difficult course . Even if it was n't as windy as yesterday , it was n't easy to score , and not many low scoring today . `` It was a very big crowd today . It was a great day , it 's big fun . It happens just one time on the European Tour , and it 's in Wentworth -- that 's why I think it 's so special . '' World number one Westwood fared better on day two , posting a score of 69 to move to one-under , while Masters champion Charl Schwartzel missed the cut in spectacular style -- finishing on 12-over .
Donald , Donald and Alvaro Quiros lead the BMW PGA Championship . The trio lead on four -under from a group of three players on four -under . Donald can become world number one if he wins at Wentworth . Eighteen-year-old Manassero shoots a round of four -under to pull level with Donald .
