Serena Williams’ Ex-Coach Minces No Words at French Open as Controversial Call Leads Lois Boisson to Crucial Win

Unreal scenes at the Philippe-Chatrier! Just a couple of days ago, the 22-year-old French tennis player, Lois Boisson, who suffered an ACL injury before last year’s French Open, stunned everyone by taking down the world number 3, Jessica Pegula, in the QF by a three-set thriller. With that win, she became the third-youngest French player to reach the women’s singles QF at Roland Garros in the Open Era. What was her reaction after that match?I’m not quite sure what to say, but playing on this court with this atmosphere was amazing, so thank you very much. I knew before the match there was a possibility [of an upset], but I knew it was going to be very, very tough. Talking about upsets, well, she created yet another historic moment in her career by reaching the SF of the 2025 French Open after defeating the teenage sensation, Mirra Andreeva, by 7-6(6),6-3. But a controversial call in that match seems to be now taking away the limelight from her incredible win. Recently, Serena Williams‘ ex-coach Rennae Stubbs also took a jibe at the French Open for the same!

What really happened, though? Well, a lot of controversial incidents took place in this match! Mirra Andreeva imploded after finding herself a 3-0 lead in the second set. The world number 361, Lois Boisson, who had taken the first set in a tie-break, won three games on the spin and then led 30-0 in the seventh game due to an error by her opponent. Venting out her anger, Mirra Andreeva took several steps forward before angrily hammering a ball into the stands with her racket. Seeing this, the Parisian crowd loudly booed and jeered Andreeva’s angry outburst.

She was even handed a code violation for her behavior. Not only that but there was also a tense moment in this match when Lois Boisson was spotted stopping the play because she believed Mirra Andreeva’s ball was out. During that time, the umpire came down and called it out. Reacting to this moment, the umpire said,She put her finger up, she stopped the point, that’s why I went down.Then Andreeva replied saying,Yeah but the ball touched the line. However, the umpire disagreed, and at that point in time, it was like 15,000 people against the 18-year-old Mirra Andreeva inside the Philippe-Chatrier. Serena Williams’ ex-coach, Rennae Stubbs, didn’t look pleased with this controversial moment.

She came up with a tweet, saying,3-3 0-30 Andreeva got screwed. U clearly see the ball push the clay off the line. Mirra actually said to the umpire,the clay went off the line& she was right, there was another ball mark there & that’s the one the used to say out. WHEN ARE WE GETTING ELECTRONIC LINE CALLING!Even last year, Alexander Zverev had highlighted afrustratingerror, which he felt might have made a big difference in the final match against Carlos Alcaraz.

The Electronic Line Calling system has been a long demand in the tennis world. Interestingly, the French Open is the only Grand Slam tournament that doesn’t use an electronic line-calling system. Seeing the umpire coming down and checking the spot, Coco Gauff’s ex-coach said,I’m m not a fan of umpires getting out of chair obviously a must though, never understand why they don’t have linesperson come over to show exact mark they called, why they need asap electronic calks like every tournament this year.”

Other than this controversy, earlier in this match, Mirra Andreeva was also spotted complaining to the umpire that the crowd was being too noisy during her serves. Overall, it was the atmosphere was absolutely electric in this match at this iconic stadium. What did Lois Boisson say after this historic win, though?
