Rising Canadian tennis star Milos Raonic will face Viktor Troicki of Serbia in his first match at the Rogers Cup in Toronto.
Troicki advanced Monday with a 6-4, 7-6 win over Alex Bogomolov Jr. of Russia.
Raonic had a bye in the first round.
In another first-round match, Jeremy Chardy of France defeated American Donald Young 3-6, 7-6, 6-0.
Chardy will take on No. 3 seed Jo-Wilfried Tsonga of France, who defeated Raonic last week in the longest three-set match in Olympic history.
In doubles, Fabio Fognini of Italy and Juan Monaco of Argentina defeated the British pair of Ross Hutchins and Jonathan Marray 7-6, 6-3.
The longer a match goes, the better Vancouver's Vasek Pospisil seems to play.
Pospisil was certainly better as the match lengthened on Monday as he beat Italy's Andreas Seppi 4-6, 6-4, 7-6 (8-6) in their first-round match at the Rogers Cup.
"I don't know what it is," the 22-year-old said. "The longer matches go sometimes the better I feel on the court and I start swinging freely and the muscle memory takes over kind of and I guess I don't think as much and my abilities take over and it's probably an advantage for me."
Pospisil — Canada's No. 2 ranked player behind Milos Raonic of Thornhill, Ont. — needed to win a third set tie-breaker to take the match. He will play Juan Monaco in the next round.
Seppi, 28, who entered the tournament ranked 26th in the world, took advantage of a service break to win the first set but then Pospisil took over and withstood the Italian's third-set rally.
"It obviously was a very close match," Pospisil said. "I had the momentum in the second set and kind of gave it back to him and was able to raise my game.
"I had chances in the third and didn't take them, the early ones, but hung in there."
Pospisil, who entered the tournament ranked 104th in the world but has been as high as 85th this year, competed in the Londono Olympics last week.
He said coming back to Canada and winning Monday was a big moment for him.
"Obviously any win in the Rogers Cup in Canada is more special," he said. "It was my third top-30 win so I don't have too many of those right now and it is obviously a big one in front of a Canadian crowd."
With the first set at 3-3, Seppi broke Pospisil's serve and maintained the advantage to take the set.
Pospisil returned the favour in the second set when he took a 3-1 lead by breaking Seppi's service in the fourth game.
But Pospisil let Seppi back into the set when he flubbed an easy overhand shot at the net. He had the advantage at deuce at the time and the simple shot would have allowed him to take a 4-1 lead in the set. But Seppi took advantage of the opportunity and rallied to take the game and break serve and the set stood at to 3-2 for Pospisil.
Seppi got even in the set at 4-4 and won the first two points on Pospisil's serve in the next game but the Canadian recovered and held serve and broke Seppi's serve to take the second set.
Pospisil got another service break to take a 2-0 lead in the third set then held his own to go up 3-0 and he was serving for the match at 5-3 when Seppi broke his service again and held his own to draw even at 5-5.
Pospisil had five match points before finally putting it away.
Polansky out in 1st round
Peter Polansky of Thornhill, Ont., could not maintain a fast start in his first-round match as Matthew Ebden of Australia pulled out a 0-6, 6-4, 6-3 win.
Ebden will play Mardy Fish in the next round of the tournament.
The 24-year-old Polansky, a wild-card entry into the tournament, needed only 19 minutes to win the first set with little opposition from Ebden but his fortunes changed dramatically as he had trouble holding service.
The tempo of the match changed in the second set as Ebden, also 24, took the first three games after an adjustment in tactics, playing back more, creating more long rallies, which were absent from the first set.
Both players had difficulty holding service in the second set but it cost Polansky more. Ebden again broke his serve to force the third set.
Ebden took a 2-0 lead in the final set before Polansky battled back to even it at 2-2.
Ebden surged ahead 5-2 before Polansky got back to 5-3 and had double-break point before Ebden rallied to put the match away.
Polansky came into Rogers Cup at his career-high ranking of No. 155 in the world.
The last time Polansky played in Toronto was in 2010 and he advanced into the second round with a victory over world No. 15 Juergen Melzer.
Polansky qualified for the 2010 U.S. Open and won his first-round match but he struggled after that and had to drop to Futures events and rebuilt his confidence with some victories.
