Andy Murray declared himself fighting fit and content with his No.3 seeding for Wimbledon after concluding his warm-up for the defence of his singles crown with a straight-sets victory over Tommy Robredo at the BNP Paribas Classic exhibition event at London's exclusive Hurlingham Club, writes Stewart Fisher.

The 27-year-old, who won 6-2, 7-6 (7-1) in front of his new coach Amelie Mauresmo, will learn the identity of his first-round opponent in the draw at 10am today, but is sure to open the tournament on the Centre Court slot reserved for defending champions.

As well as declaring himself free of the back problems which hindered him after that victory 12 months ago, the Scot defended the All England Club's unique seeding policy, which takes players' grass court records into consideration. The result was that he is seeded two places higher than his world ranking of No.5.

"I think the way they do it is correct," he said, "although some people will probably say 'well you would say that'. So few tournaments are played on grass, which is a specialist surface. Some guys, like Robredo for example, will only play one tournament on grass every year. What they have done with the seedings helps; I would rather be seeded third than seeded fifth."
