Kyrgios returns to winning ways in Canada

Thousands of fans pack into stadium to greet Wimbledon champion Simona Halep

Nick Kyrgios shrugged off his recent injury troubles to record his first victory since May at the Rogers Cup in Montreal.

The Australian has been plagued by a hip problem in recent weeks, forcing him to retire at Queen's, Wimbledon and last week's Citi Open in Washington.

But he looked in good shape in Montreal on Monday as he dispatched Viktor Troicki 6-1, 6-2 to book his place in the second round.

Looking refreshed, Kyrgios needed just 51 minutes to secure the easiest of wins, although afterwards he warned the injury could flare up again at any moment.

"I'm feeling it all the time," Kyrgios said.

"It's not something that is just going to heal. I can compete so that's the most I can do at the moment."

The match against Troicki would have been over even quicker had Kyrgios not struggled to finish the job. He needed all of seven match points before finally coming out on top.

"I just wanted to come out here and try and get the win," said Kyrgios.

"I've been struggling the last couple of months.

"He's been struggling as well with injuries so all the best to him but I'm just happy to get out here and get a win."

Other early winners on Monday included Mischa Zverev, Robin Haase, Benoit Paire and Gael Monfils.

Rafael Nadal and Roger Federer are both in Montreal this week but have received byes into the second round.
