Murray cruises through

Andy Murray had little trouble in overcoming Lukas Rosol to book his place in the US Open second round.

The newly-crowned Olympic champion dropped just seven games on his way to a 6-3 6-2 6-2 victory in New York and he will now face world number 45 Marcel Granollers.

The first five games went with serve before Murray broke his opponent to put him on course for the first set and when he moved 3-0 up in the second the pre-tournament favourite was in cruise control.

"At the start of the match he had a few chances the first couple of service games. He came out going for his shots," Murray said.

"I got through that tricky period right at the start where he's hitting the ball really well, kind of adjusting to the conditions.

"Once I got through that, I settled down and played I think a really good match."

Nick Kyrgios also enjoyed a straight sets win but the Australian caused controversy when he refused to shake hands with umpire Ali Nili at the end of the match.

Kyrgios was unhappy with a number of line calls during the course of his 6-4 6-4 6-4 defeat of Britain's Aljaz Bedene and made his feelings clear by saying "You have one job, you just have one job" as he left the club.

Earlier, Bernard Tomic had shocked spectators on the same court when he made lewd comments at a heckler.

The 23-year-old, who was beaten by Damir Dzumhur of Bosnia, apologised for his comments, which were caught on a courtside microphone.

Elsewhere, Stanislas Wawrinka enjoyed a straight sets win over Fernando Verdasco.

THe Swiss third see had lost three of his five matches against Verdasco, but he was too strong for the Spaniard this time, prevailing 7-6 6-4 6-4 to set up a second round match against Alessandro Giannessi.

"I think it was a great match, especially for first round. You never expect to play your best game and be full of confidence, but I think the level was quite high," said Wawrinka.

"Fernando is a tough player to play. He can be really aggressive. He don't give you so much rhythm, so it's not easy. But I think in general I'm happy with what I did. I was really focused on myself. I was moving really well for first one. I'm getting some confidence from that match.

"My expectations for myself are more higher than before. For me, the most important thing is to focus on what I can control, all the practice, all the schedule, giving everything every practice being ready for the tournament.

"Right now I know I'm ready for here, for the tournament. And now I'm going to see how I'm going to deal with the pressure, with the match, and trying to play the best I can until as far as I can."

Meanwhile, Serena Williams defeated Ekaterina Makarova 6-3 6-3 on Arthur Ashe Stadium.

Williams has been struggling with a shoulder injury in recent weeks but it did not look to be too much of an issue on Tuesday as the world number one hit 12 aces on her way to a first round victory.

"I didn't hit my serves as hard as I normally hit them. I just went for more placement. I didn't go for the big 120s, just the regular," Williams said.
