Andy Murray believes his prospects of glory at Wimbledon have been enhanced by the speed of his two opening victories.

Murray beat Robin Haase 6-1, 6-1, 6-4 in an hour and 27 minutes on Court One, meaning he has taken less than four hours to reach round three after another straight-sets victory over Mikhail Kukushkin on Tuesday.

Italy’s Andreas Seppi awaits in the third round today and Murray was relieved to save energy, with the likes of Jo-Wilfried Tsonga and Roger Federer potentially to come.

“In grand slams you have to try to conserve energy when you can because the two weeks can be quite draining physically and mentally,” Murray said.

“If you can get yourself off the court quickly and capitalise if your opponent maybe isn’t playing as well, if you’re on your game, (you have to) try to push yourself to keep playing that way. It can pay off towards the end of the tournament so I’m glad I got done quickly.”

Murray felt dissatisfied after his battling win over Kukushkin but the British No1 raised his level against Haase, with a more aggressive and dominant display.

After the match, Murray threw his wristband towards the Duchess of Cornwall as she sat in the stands and it was caught by All England Club chairman Philip Brook, who then passed it to the Duchess.

A Clarence House spokeswoman said the Duchess and Murray met after his win so she could ‘’pass on her congratulations’’.

And Murray said: “The wristband actually hit the chairman of Wimbledon. The Duchess opened up her bag and my wristband was in there, so he obviously had given it to her.” 

Murray will now focus on Seppi, who has never been past the fourth round in SW19 and has failed to win a set in six consecutive defeats to the world No 3.

The Italian has enjoyed an encouraging year, however, after he inflicted a shock defeat on Federer at the Australian Open, before losing to the Swiss in the final at Halle last month.
