Top-ranked Novak Djokovic has beaten 10th-seeded Gael Monfils 6-3 6-2 to reach the Toronto Masters final and improve to 12-0 against the Frenchman.

The winner in 2007, 2011 and 2012 in the hardcourt event that rotates between Toronto and Montreal, Djokovic will face third-seeded Kei Nishikori of Japan.

Nishikori beat second-seeded Stan Wawrinka of Switzerland 7-6 (8-6) 6-1 in the first semi-final.

Djokovic has six victories this year and 65 overall.

The 29-year-old Serb has 12 grand slam titles, winning this year in Australia and France.

Monfils was coming off a victory last week in Washington.

Switzerland’s Stan Wawrinka lost his momentum in a surprise turnaround as the second seed went down in the semi-finals of the Toronto Masters to Japan’s Kei Nishikori 7-6 (8-6) 6-1.

The result puts third seed Nishikori into his second Masters 1000 final of the season, after losing to Novak Djokovic in a Miami title bid in April.

Wawrinka put up a fight in the opening set, earning an early break for 3-1 but losing his edge as Nishikori broke back for 4-5.

The first set went into a tiebreaker, where two-time grand slam winner Wawrinka let a 3-1 lead slip away.

He missed on two set point chances – the second on a double-fault – before Nishikori seized the opener on his first chance.

From that point, Wawrinka barely registered as he went down in 88 minutes.

“I just tried to concentrate in the tiebreaker,” Nishikori said.

“I played a point at a time. I took confidence into the second set, tried to be aggressive on returns and stood farther back than usual.”

Wawrinka had led their series 3-1 going into the semi-final, with Nishikori still testing his form after a rib injury that forced him to quit a Wimbledon match.

Nishikori’s win was his 40th this season, while Wawrinka now stands 31-11 with titles at Chennai, Dubai and Geneva.

Wawrinka will now head to the Rio Olympics after an effort in which he committed 37 unforced errors and dropped serve three times.
