ANDY Murray played like a dream to book his place in the Wimbledon third round then saw his supposedly nightmarish SW19 draw continue to open up.

The Scot, who ruthlessly dispatched Robin Haase by a 6-1, 6-1, 6-4 score on Court No 1, lost one prospective quarter final opponent when world No 7 David Ferrer withdrew due to injury on the eve of the tournament, and yesterday there was an even more high-profile faller when Rafael Nadal crashed out to Dustin Brown, the flamboyant Jamaican-German. Amazingly, the Mallorcan's 7-5, 3-6, 6-4, 6-4 defeat on Centre Court was the fourth successive year in which the two-time Wimbledon champion had gone down to a player outside the world's top 100.

Nadal gave credit to his inspired opponent, who joined a list of giantkillers which includes Lukas Rosol, Steve Darcis and Nick Kyrgios. He said he couldn't be sure if he would ever return to the levels which saw him take this title in 2008 and 2010, reaching the final on three other occasions.

"It is obvious that 2012 and 2013 were not an issue," said Nadal. "I had too much problems on my knees. Last year and this year, I had no problems at all with my knees. I was ready to compete. I lost. I don't know if I will be back to the level of 2008 or 2010, or 2007 or 2006 or '11. But I am a good loser. When I am not that good, I always accept it. Accept and keep going, it's the only way."

Murray, meanwhile unwittingly presented the Duchess of Cornwall with a memento after bagging his third round place. The Scot threw his sweatband into the crowd at the conclusion of his match against Robin Haase of the Netherlands, only for it to inadvertently whistle past her ear and be grabbed instead by Philip Brook, the chairman of the All England Club. When the World No 4 met the wife of the future king after the match, the Scot revealed he had presented it to her as a gift.

"The wristband actually hit the chairman of Wimbledon who was there with her," said Murray. "I saw her briefly after the match. The Duchess opened up her bag and my wristband was in there, so he obviously had given it to her."

The Scot took less than an hour and a half to dispose of the World No 78 on Court No 1, a venue where he has never lost in ten years. He said he was delighted to progress in such ruthless fashion against an opponent who has presented him with difficulties in recent years. In last year's US Open first round, the Scot had cramped up badly before winning match in four sets.

"I wanted to make sure," said Murray. "I've obviously had some tough matches with him [Haase] in the past. I know when he's on he can make it extremely difficult. He can be pretty flashy and play two or three great games in a row so I wanted to make sure that I didn't give him that opportunity.

"In Grand Slams you have to try to conserve energy when you can because the two weeks can be draining physically and mentally," he added. "It can pay off towards the end of the tournament."

The Scot now faces Andreas Seppi of Italy in Saturday's third round. The 31-year-old Italian, ranked No 27 in the world, overcame Borna Coric in five sets after the talented Croatian youngster required treatment for a hamstring problem. "Seppi has had such good results this year," said Murray. "He made the final a couple of weeks ago in Halle and plays well on the grass. He won against Roger at the Australian Open this year. So he's capable of playing some top tennis."

Murray was joined in the third round by his friend James Ward, the Londoner with whom he practises regularly at his home in Miami. Ward overcame Czech youngster Jiri Vesely and now faces Vasek Pospisil of Canada.
