Andy Murray cruises past Lukáš Rosol at US Open to set up meeting with Marcel Granollers

The second seed was in fine form on Arthur Ashe Stadium and didn't drop serve once against a dangerous opponent as he began his quest to land his second title at Flushing Meadows and a third major title this year following victories at Wimbledon and the Rio Olympics.

British No.1 Murray was slick and clinical in a ruthless display against world No.82 Rosol, winning 83 per cent of points behind his first serve en route to a masterclass under the lights in New York.

"I served very well," said Murray, who hit 11 aces and made just 17 unforced errors.

"I don't think I had any break points against me, which was good, I had good variation on the second serve as well.

"It was a tough start to the match and once I got the break up, I started to relax and play well."

Murray, who improved his win-loss record in 2016 to 51-7, will take on Spain's Marcel Granollers in the second round on Thursday.
