German second seed Alexander Zverev claimed his third successive comeback win at the French Open to reach his first Grand Slam quarter-final on Sunday, edging Russian Karen Khachanov in five sets.

The 21-year-old played some stunning tennis in the closing stages of a dramatic 4-6, 7-6 (7/4), 2-6, 6-3, 6-3 fourth-round victory and will next face Dominic Thiem who reached a third successive quarter-final in Paris by seeing off Japan’s Kei Nishikori 6-2, 6-0, 5-7, 6-4.

World number 38 Khachanov has now lost at the last-16 stage at Roland Garros twice in a row, while Zverev ended his wait for a maiden major last-eight appearance at the 12th attempt.

“Well, I’m young, so I might as well stay on court, get some practice and entertain you guys,” smiled Zverev, who is bidding to become the first German man to win the French Open since 1937.

“Me and my brother (Mischa) are guys that spend three, four hours a day in the gym, lifting heavy weights, on the treadmill. It paid off today.” A tight first set heated up in the 10th game when Zverev saved two set points, the second after becoming incensed when the umpire overturned a line call of out from a Khachanov shot.

But the Russian sealed the set at the third time of asking, leaving the world number three needing a fightback for the third consecutive match.

There was excitement at the end of the second set too as a marathon game saw Zverev fail to serve it out to level the match, firing long on Khachanov’s fifth break point after wasting three set points.

But the German gathered himself, taking a tie-break as the momentum swung back in his favour.

That proved a false dawn for Zverev, though, as Khachanov eased through the third set with some powerful hitting.

But Zverev, as he did in his wins over Dusan Lajovic and Damir Dzumhur, forced a decider, sealing the set with an ace after saving two break points.

And he secured an impressive victory, finishing the match with 63 winners and 17 aces.

Thiem, the only man to beat Rafael Nadal on clay this year, held off a short-lived Nishikori revival on Court Philippe Chatrier to set up a clash with Zverev.

“I think that’s the matchup most of the fans in Germany and Austria were hoping for when they saw the draw,” he said.

“He’s an amazing player. I mean, probably now the third-best after Rafa and Roger (Federer). So it’s going to be an amazing challenge for me.” Former champion Novak Djokovic faces Fernando Verdasco later in the day, looking to reach the last eight of a Grand Slam for the first time since Wimbledon last year.

US Open champion Sloane Stephens cruised past Estonian Anett Kontaveit 6-0, 6-2 to book a last-eight spot for the first time.

Stephens, the 10th seed, had previously made the fourth round for four successive seasons and will next play either Australian Open champion and second seed Caroline Wozniacki or Russia’s Daria Kasatkina.

American 13th seed Madison Keys also reached her first Roland Garros quarter-final with a 6-1, 6-4 win over Romania’s Mihaela Buzarnescu.

Keys, the US Open runner-up to Stephens last year, will face Kazakhstan’s Yulia Putintseva for a place in the semi-finals, after the world number 98 saw off Barbora Strycova 6-4, 6-3.

“First week, my goal is to get to the second week,” said 23-year-old Keys.

“Then once you get to the second week, every match obviously has more nerves, and there’s more on the line.” On Monday, all eyes will be on the showdown between Serena Williams and Maria Sharapova, with the latter trying to end an 18-match losing streak to her bitter rival.

Three-time champion Williams is playing her first Grand Slam tournament since taking time off last year due to pregnancy, while Sharapova is at Roland Garros for the first time in three years after serving a doping ban in 2016 and being refused a wildcard 12 months ago.
