'When are we getting electronic line calling?' - Rennae Stubbs backs Mirra Andreeva following controversial call during Roland Garros quarterfinal

Russian tennis sensation Mirra Andreeva was facing a huge task on Wednesday as she took on surprise quarterfinalist and home favorite Lois Boisson in the Roland Garros quarterfinals. With the crowd fully on Boisson's side, it was a controversial call during the match that made headlines.

Boisson was competing at her first Grand Slam event, and had stunned the tennis community by reaching the quarterfinals ranked World No.361. The Parisian crowd lent their support to the Dijon native, with some booing Andreeva as the Russian struggled to maintain her composure.

Controversial decision prompts discussion for electronic line calling

Andreeva lost the first set in a close tiebreak, but surged to a 3-0 lead in the second set. However, Boisson would mount a comeback, leveling the set at 3-3. This led the raucous crowd to cheer even more for Boisson, with a few booing Andreeva. At one point, a visibly shaken Andreeva yelled at the crowd to "shut up" as momentum swung to her French opponent's side.

However, things escalated in the second set due to a dispute over a line call. With Andreeva serving 0-30 at 3-3, Boisson would successfully challenge a line call, leading to Andreeva arguing with the umpire as the Russian believed the clay had been moved by the ball. The umpire would stand by the call, with Andreeva eventually losing in straight sets as Boisson advanced to her first Grand Slam semifinal.

Following the match, retired WTA doubles specialist Rennae Stubbs would voice her opinion on the matter. The former coach of Serena Williams backed Andreeva, and questioned why electronic line calling was not yet in use at Roland Garros.

"3-3 0-30 Andreeva got screwed," wrote Stubbs on Twitter. "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!"

Joining Stubbs in her outburst was Brad Gilbert, former coach of American tennis star Coco Gauff. The renown coach would echo Stubbs sentiments, stating the French Open needs to introduce electronic line calling in order to avoid such situations.

"I’m not a fan of umpires getting out of chair," opined Gilbert on Twitter. "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 calls like every tournament this year."
