French Open: Jo-Wilfried Tsonga Stuns Fourth Seed Tomas Berdych, Sets up Quarters Clash v Nishikori

Jo-Wilfried Tsonga beat fourth seed Tomas Berdych at Roland Garros on Sunday, winning 6-3, 6-2, 6-7 (5/7), 6-3 to show the way into the quarter-finals for a five-strong French contingent. (Sania Mirza-Martina Hingis reach quarters)

Played in cold, damp conditions, Berdych looked out of sorts from the start, allowing Tsonga to dominate rally after rally with his powerful serve and shot-making.

The Czech player rallied briefly in the third set as Tsonga's level dropped, but after a brief scare at the start of the fourth set, Tsonga won five games in a row to move through. (Victoria Azarenka calls for review system in French Open)

The 14th seeded Frenchman will next play Japanese fifth seed Kei Nishikori for what would be his second ever appearance in the French Open semi-finals after that of 2013.

"I was into the match from the start, but he is a great champion and stuck with it," Tsonga said. (Somebody will break my record: Nadal)

"I had a little bit of a concentration lapse and I had been talking to my coaches about that.

"And that's what helped me win in four sets. That's the best match I have played in some time." (Kei Nishikori ends Japan's 82-Year wait in French Open)

With menacing dark clouds overhead sending down drops of rain there were doubts that the match could get going at all, but when it did Tsonga immediately looked the stronger, breaking in the fourth game to take a 3-1 lead.

Two games later the rain grew in intensity and there was a delay of a few minutes that confused both players and had the umpire working overtime pondering what to do next.

But they all stuck it out courtside and on the resumption Tsonga duly pocketed the opening set.

He then broke again to start the second and clearly had Berdych on the back foot, struggling to deal with the sheer power of the Frenchman's shots.

A third break of serve for Tsonga in the fourth game effectively took care of the set and there looked no way back for Berdych, who had a 1-5 five-set win-loss record at Roland Garros coming into this year's tournament.

The third set though was more evenly balanced with Tsonga failing to serve out for the win at 5-4, and he paid the price in the ensuing tie-breaker letting slip a 3-0 lead to allow Berdych a way back into the match.

Tsonga is one of five French players into the last 16, equalling the best home showing at Roland Garros in the Open-era since 1968.

But on the two previous occasions that happened, only one man reached the quarter-finals.

Scheduled on the centre court after Tsonga-Berdych was the eagerly-anticipated matchup between 17-time Grand Slam champion Roger Federer and Roland Garros showman Gael Monfils, whose succession of unpredictable five-set dramas have won him a special place in French hearts.

Out on Court Suzanne Lenglen current French number one Gilles Simon had a meeting with last year's Australian Open winner Stan Wawrinka in another Franco-Swiss clash.

The two other Frenchmen into the last 16 -- Richard Gasquet and Jeremy Chardy -- were down to play their ties on Monday with Gasquet against top see Novak Djokovic and Chardy facing third seed Andy Murray.

No Frenchman has won at Roland Garros since Yannick Noah in 1983 and prior to that it was Marcel Bernard in 1946.

Nishikori's win made him the first Japanese man in 82 years to reach the French Open quarter-finals.

Jiro Satoh was the last Japanese man to enjoy such a run in Paris when he went on to the semi-finals in 1931 and 1933.

Nishikori hadn't played since Wednesday after scheduled third round opponent Benjamin Becker withdrew with an injury.

Asked about his thoughts about taking on Tsonga in the last eight, Asia's top player said he expected it to be a "fun match."

"We haven't played for a long time, maybe couple of years," he said.

"But, you know, he was injured and he came back now and he's coming back very strong. You know, he has a big serve, big forehand. He's always a dangerous player."
