San Francisco Frontiers - Boisson continues dream French Open run, Djokovic, Sinner eye semis

Boisson, making her debut at a Grand Slam event, powered her way to a thrilling 7-6 (8/6), 6-3 victory on a raucous Court Philippe Chatrier to become the first Frenchwoman to reach the semis since Marion Bartoli in 2011.

The 22-year-old, who was due to play at last year's French Open but suffered a knee injury the week before the tournament, is the lowest-ranked woman to reach a major semi-final in 40 years.

"It was incredible to play in front of this crowd and feel support like that," said Boisson, after hitting 24 winners past Russian sixth seed Andreeva to follow up her fourth-round win over world number three Jessica Pegula with an even more surprising victory.

A dramatic first set saw Andreeva miss a set point after leading 5-3, before Boisson fought back only to see three chances of her own come and go in a marathon 12th game.

But the wildcard fought off another set point in the tie-break, before taking her next opportunity, cupping her ear towards the adoring crowd in celebration.

Andreeva gathered herself and quickly built a 3-0 lead in the second set, only to be left jumping up and down in anger after a missed backhand gave Boisson a much-needed hold of serve.

The 18-year-old Andreeva started to crumble under the pressure, being given a warning for slamming a ball into the top tier of the stands as the atmosphere heated up under the Chatrier roof.

She was roundly booed when she then argued with the umpire over a line call, and was broken later that game after another double-fault to suddenly trail 4-3.

Boisson made it six consecutive games to secure a seismic victory as Andreeva, one of the pre-tournament favourites, completely unravelled.

Second seed Gauff battled back from a set down to defeat fellow American, and Australian Open champion, Madison Keys in an error-strewn opening match 6-7 (6/8), 6-4, 6-1.

The former US Open champion upped her level enough after dropping the first set to get through a quarter-final littered with 14 double-faults and a whopping 101 unforced errors.

"It means a lot, especially getting through this tough match today, it wasn't an easy match and I'm very happy to get through it," she said.

Gauff, the 2022 losing finalist, will be hoping to go at least one better than when she lost to Iga Swiatek in last year's semi-final.

Swiatek continues her bid for a fourth consecutive Roland Garros title in a blockbuster clash with world number one Aryna Sabalenka in Thursday's other semi-final.

- Zverev eyeing Djokovic scalp -

Djokovic will compete in a record 19th French Open quarter-final against last year's runner-up Alexander Zverev in the night-session match.

The German third seed will be well rested after his last-16 opponent Tallon Griekspoor retired on Monday with an abdominal injury while trailing 6-4, 3-0.

Zverev, who lost to Carlos Alcaraz in last year's final, continues his latest bid for a maiden Grand Slam title after three runner-up finishes.

"For me, Carlos is the favourite. Then I would say the next three in line are Jannik, myself, and Novak, right? I still believe that," said Zverev, who could meet world number one Sinner in the semi-finals.

Zverev has made at least the last four at the past four French Opens and is into his seventh quarter-final.

The 28-year-old has won five of his 13 career matches with Djokovic, including in Melbourne in January when the Serb retired injured from their semi-final.

- 'Pretty dominant' -

Djokovic, a three-time champion at Roland Garros, is just the second player to record 100 wins at the event after 14-time winner Rafael Nadal (112).

"It's a very pretty number, but 101 victories sounds better," said 38-year-old Djokovic who has reached the quarter-finals at the clay-court major for a 16th consecutive year.

World number six Djokovic is chasing a record 25th major title.

Italian Sinner takes on unseeded Kazakh Alexander Bublik, who hailed his emotional four-set win over fifth seed Jack Draper in the last 16 as the "best moment of his life".

Sinner leads 62nd-ranked Bublik 3-1 in previous meetings.

The Italian reached the semi-finals last year where he lost a five-set battle to Spaniard Alcaraz.
