Andy Murray won the US Open in 2012 before success at Wimbledon in 2013 and 2016Andy Murray is through to the second round of the Canadian Open in Toronto after a straight-set victory over Lorenzo Sonego in blustery Toronto.
Murray, 36, beat the Italian 7-6 (7-3) 6-0 in two hours and nine minutes at the ATP Masters 1000 event.
The Scot previously won the tournament in 2009, 2010 and 2015.
"I managed to sneak through the tie-break and after that he was obviously a bit disappointed, and I relaxed a little bit," said Murray.
The three-time Grand Slam winner had to save two set points at 5-4 on his own serve, and dropped the first two points of the tie-break, before he won a marathon 88-minute first set.
The second second set was more of a formality as Murray backed up an early break with two more and grabbed match point at the first opportunity.
Murray will face either Canada's Felix Auger-Aliassime or Max Purcell of Australia in the next round.
"Obviously I've had success here in the past," added Murray.
"It was a very long time ago, but I have good memories from this tournament. I love playing here and hopefully I can build a bit of momentum."
