First Slam semi-final for Czech Republic's Barbora Krejcikova

Paris (AFP) - Barbora Krejcikova took a rollercoaster ride into a maiden Grand Slam semi-final at the French Open on Wednesday as Novak Djokovic and Rafael Nadal closed in on another blockbuster clash.

Czech world number 33 Krejcikova knocked out American 17-year-old Coco Gauff 7-6 (86), 6-3 after saving five set points in the opener and then needing six match points to finish the job.

She goes on to face either eighth-seeded defending champion Iga Swiatek, the only top 10 player to reach the quarter-finals, or Greece’s Maria Sakkari.

Gauff, the 24th seed and the youngest quarter-finalist at a major in 15 years, was undone by seven double faults and 41 unforced errors.

“I never really imagined I’d be standing here one day on this court, especially in singles, and being able to win,” said Krejcikova, who had been so paralysed by fear before her last 16 victory over Sloane Stephens that she locked herself in a stadium office and wept.

Krejcikova, now on a 10-match winning streak, is having a busy week. She is also in the semi-finals of the women’s doubles.

Swiatek, Poland’s first Grand Slam singles champion, is on a run of 22 straight sets won in Paris.

She is also winning rave reviews including from Britain’s two-time Wimbledon champion Andy Murray who tweeted his admiration for the Pole’s style of play.

“Thank you Sir Andy! Are you by any chance up for a practice? I really need to improve my skills on grass,” she tweeted back to the former world number one.

Murray replied: “Anytime just promise to go easy on me as I’m a bit old and fragile now!”

Like Krejcikova, Swiatek is also into the women’s doubles semi-finals with US partner Bethanie Mattek-Sands.

- Djokovic, Nadal on collision course -

Later Wednesday, world number one Djokovic, the 2016 champion, and an 18-time Grand Slam title winner, faces Italian ninth seed Matteo Berrettini.

Victory would put the Serb into the semi-finals in Paris for the 11th time and only two wins away from becoming only the third man in history to win all four majors twice.

Djokovic had to dig deep against another Italian to guarantee his passage to a 15th quarter-final in Paris.

He was given a huge scare in the fourth round when 19-year-old Lorenzo Musetti raced into a two sets lead before running out of steam and quitting in the fifth.

“Berrettini has a big serve, big forehand. Two big weapons. He’s in form,” said Djokovic who defeated the Italian in their only previous meeting at the 2019 ATP Tour finals.

Rafael Nadal is in his 15th French Open quarter-final

Djokovic will be into a 40th Grand Slam semi-final if he succeeds where Nadal could be waiting.

Berrettini has been solid on clay this year, finishing runner-up in Belgrade and Madrid but the highest-ranked player he has faced in Paris is world number 91 Kwon Soon-woo, his third round opponent.

He also arrives fresher than Djokovic have been given a walkover into the last eight when Roger Federer withdrew from the tournament.

Nadal, who is bidding to capture a 14th Roland Garros and record-setting 21st major, is on a run of 35 consecutive winning sets at the French Open.

The reigning champion meets Argentine 10th seed Diego Schwartzman.

Nadal boasts a 10-1 record over Schwartzman, including a straight sets win in the semi-finals of last year’s delayed French Open.

A victory for Nadal would put him into the last four at a Slam for the 35th time.

Meanwhile, the latest easing of Covid-19 restrictions in France from Wednesday and a later curfew from 11pm means a rise in the number of spectators at Roland Garros.

The final evening session of the tournament will have spectators for the first time with 5,000 fans able to watch the Djokovic-Berrettini quarter-final.
