Sinner on Hitting with Boisson: An Amazing Level of Play

“[It’s] a different game style for a woman, because the ball is quite high and quite spinny,” Jannik Sinner said of Lois Boisson.

Jannik Sinner tuned up for today’s Roland Garros quarterfinals hitting with a clay-court Cinderella. 

World No. 1 Sinner hit with French No. 361 Lois Boisson hours before facing Alexander Bublik on Court Philippe Chatrier.

It proved to be a productive practice for both.

The top-seeded Sinner stomped buddy Bublik 6-1, 7-5, 6-0 to charge into his second straight Roland Garros semifinal.

Reigning US Open and Australian Open champion Sinner extended his major match winning streak to 19 and made history as the first Italian man to reach six Grand Slam semifinals.

Wild card Boisson continued her remarkable Roland Garros run.

The 22-year-old from Dijon, France stunned 2024 semifinalist Mirra Andreeva 7-6(6), 6-3 to burst into Roland Garros semifinals in her maiden major main-draw appearance.

Sinner, who met Boisson before this French Open fairytale run, said he was impressed by her heavy topspin forehand during this morning’s hitting session and called her overall level of play “amazing.”

“I think the level she produces is amazing, no? Very consistent,” Sinner told the media in Paris. “Very clay court style, you know, with the forehand, a lot of topspin.

“Today it was raining, so I called here, the desk, you know, if there was some free spot, because I don’t want to risk to go on court without warming up. So we arrived here quite early.

“Yeah, she said straightaway yes, and we hit some balls.”

Generating a radical RPM count on her ferocious forehand, Boisson has tormented two Top 10 players in a row—Andreeva and No. 3 Jessica Pegula in the fourth round—trampolining shoulder-high topspin off the terre battue.

“It was a very consistent warmup for a different game style for a woman, because the ball is quite high and quite spinny,” Sinner said of Boisson. “Physically very strong. She deserves to be in the position where she is right now, and we wish her all the best for the future.”

Boisson, who suffered an ACL injury last season and just returned to the Tour in February, isn’t satisfied with her semifinal surge.

Next up for Boisson will be a very tough test in 2022 finalist and No. 2 seed Coco Guaff.

“I think every kids who play tennis have the dream to win a slam,” Boisson told the media in Paris. “More for French player to win Roland Garros, for sure.

“So, yeah, it’s a dream. For sure I will go for the dream, because my dream is to win it, not to be in the semifinal. So I will try to do my best for it.”
