World number one Novak Djokovic moved into the semi-finals of the Rogers Cup in Montreal with a 6-2 6-1 victory against Gael Monfils of France.
Djokovic needed only 73 minutes to record his 51st win in 52 matches this year as he seeks a ninth title of 2011.
In the last four he will play another Frenchman, Jo-Wilfried Tsonga, who beat eighth seed Nicolas Almagro 6-4 6-4.
Mardy Fish beat Stanislas Wawrinka and faces a semi-final with unseeded Janko Tipsarevic, who beat Tomas Berdych.
Djokovic, whose sole defeat this year came against Roger Federer in the French Open, had won all six previous meetings with Monfils and quickly took the upper hand again.
He broke to lead 4-2 and finished off the set with another break before surging to 5-0 in the second.
"I played really, really fast and tried to constantly put pressure on Gael because I didn't want to give him any time to get back to the match or to think about what he's going to play," said the 24-year-old, who is yet to drop a set in the tournament.
Monfils said: "He was certainly the best Novak I ever met. He was too strong. I played well, I hit the ball hard but I never had any solution to finish off a point."
Fish, a 6-3 6-7 (8-10) 6-0 winner over Switzerland's Wawrinka, broke three times to grab the opening set but both players struggled with their serve in the second set that featured eight service breaks - four by each man.
Wawrinka prevailed in a lengthy tie-break but collapsed in a one-sided deciding set.
"The second set was very strange for both of us," said Fish, who failed to win a match in previous visits to the Rogers Cup in 2003 and 2008.
"We couldn't hold serve to save our lives but we returned really well ... There's the positive, I guess."
Tipsarevic, who will move into the world top-20 for the first time after his impressive performances this week, secured his first Masters Series semi-final with a 6-4 6-4 win against seventh seed Berdych.
"It means a lot, it was a goal," the 27-year-old Serb said of his promotion from a previous ranking of 24. "My goals this season were to finish the year top 20 and to win an ATP title."
Andy and Jamie Murray's doubles campaign came to an end with a 6-4 6-4 defeat by Germany's Florian Mayer and Czech Tomas Berdych, who now face a semi-final against another set of brothers, American top seeds Bob and Mike Bryan.
