Portugal Colonial - Murray, Zverev master Toronto wind to advance

Britain's Murray worked through a marathon opening set before dominating the second for a 7-6 (7/3), 6-0 victory over Italy's Lorenzo Sonego.

Germany's Alexander Zverev, who defeated Roger Federer for the 2017 Canadian title, reached the second round by defeating Dutchman Tallon Griekspoor 6-4, 7-6 (7/3).

The 36-year-old Scotsman, with three Canadian titles on his resume, earned his first victory in the country since his 2015 trophy as he defeated the Italian in two hours, eight minutes in a challenging wind.

Murray won the pair's only previous encounter last February in Doha, saving three match points. Murray, ranked 40th to his opponent's 39th, also lifted the trophy here in 2009 and 2010.

Murray's opening set lasted 90 minutes, with the two-time Wimbledon winner saving set points in the 10th game.

He profitted from Sonego's 44 unforced errors to sweep into the second round.

"I'm really pleased to have won. Those were blustery conditions," Murray said. "The wind was changing conditions during the points.

"We knew it would be like this after hitting here this morning. The breeze added a bit of stress."

Murray said getting through the first set was a challenge.

"It was tight, there were a lot of opportunities on both sides," he said. "I managed to sneak through the tiebreaker, he probably got disappointed and I relaxed a bit in the second set.

"I hope to build confidence and win a few matches," said the three-time Grand Slam champion, who exited last week in the Washington third round to Taylor Fritz.

"I had success here but it was a long time ago. Hopefully I can build some momentum."

Former ATP number two Zverev, seeded 13th and playing here for the first time in four years, extended his current win streak to six matches after taking his home event in Hamburg last month.

The German battled the wind for an hour and three-quarters to prevail.

He sent down an ace for three match points and won as his opponent missed on a drop shot attempt.

Zverev ended with 27 winners and 20 unforced errors -- the exact reversal of Griekspoor's 20 and 27.

"It was a win in tough conditions," Zverev said. "It was very windy.

"I'm just happy to get through. I hope it gets nicer to play tomorrow."

Britain failed to get two men into the second round as 11th-seeded Cameron Norrie went down 7-5, 6-4 to weekend Los Cabos finalist Alex de Minaur of Australia.
