Casper Ruud and João Fonseca’s blockbuster fourth-round clash at the 2026 French Open has reignited the controversy over the Major’s decision to retain human line judges rather than adopt electronic line calling, which is now standard at tournaments around the world. Several members of the tennis community are up in arms over a contentious line call that hampered Ruud’s chances in the match.
Inside the Line Call Drama During Casper Ruud and João Fonseca’s French Open Battle
Two days after rallying from two sets down to oust Novak Djokovic from the French Open, Fonseca took the upper hand in his contest with Ruud by clinching the opening set 7-5. The second headed into a tiebreak, with the Norwegian holding a set point at 8-7.
At that crucial moment, Fonseca fired a forehand that was called out by a spectator instead of a line judge. Chair umpire Louise Engzell checked the mark and ruled the ball in, which erased Ruud’s set point and prevented him from leveling the match. Moments later, a Hawk-Eye replay showed that the ball had landed out, adding to the drama.

Fonseca went on to win the tiebreak before sealing a 7-5, 7-6(8), 5-7, 6-2 victory over Ruud to advance to the quarterfinals of a Grand Slam for the first time in his career. However, his victory was overshadowed by a raging debate about the contentious line call that cost the Norwegian the second set.
Former world No. 1 and four-time Grand Slam champion Jim Courier criticized the decision not to use electronic line calling while providing commentary for the match, emphasizing that match results should not be determined by human error.
“I’m not saying electronic line calling is perfect but it makes far fewer mistakes than humans. Matches should be decided by the players not by people, not in 2026,” Courier said.
Serena Williams’ former coach Rennae Stubbs firmly agreed with Courier’s assessment.
“From Jim Couriers mouth to gods ears )ie the FFT,) give us ELECTRONIC LINE CALLING STAT!!!!” she posted.
Meanwhile, tennis journalist Myles David accused the French Open of consistently lagging behind the other Grand Slams when it came to implementing modern innovations. Former world No. 3 Pam Shriver backed his sentiment and condemned the “pattern of inflexibility.”
“#RolandGarros was the last slam to build a roof over their biggest stadium and it appears they’ll also be the last to adopt electronic line calling. Always behind,” David said.
“But leads the way in hazards in field of play that cause danger to players. Overall a pattern of inflexibility hurts the tournament keeping up with the other three majors that have a more growth mindset,” Shriver responded.
Andy Roddick also weighed in on the “massive controversy,” stressing the consequences of the disputed line call for Ruud.
“If they use electronic line calling, which is more accurate than humans. If they use that, it’s 1-1, not 2-0 for Fonseca. They show the replay. Only tournament in the world that doesn’t use electronic line calling is this is this tournament. So massive controversy, as it should be,” he said.
However, former doubles world No. 1 Paul McNamee went against the grain and disagreed with Courier, arguing that technology is not infallible either.
“I gave Jim his first gig as a commentator at the Australian Open. He’s top shelf, but in this case I disagree with him. Technology is not perfect either, so may the authenticity of ball marks prevail…on clay, at Roland Garros, tennis is gladiatorial uniquely with human arbiters,” McNamee said.
Despite the controversy, No. 28 seed João Fonseca will remain focused on his upcoming quarterfinal clash at Roland Garros. Following his win over Casper Ruud, the 19-year-old will lock horns with No. 26 seed Jakub Menšík, who set up the highly anticipated encounter with a hard-fought 6-3, 7-6(6), 4-6, 2-6, 6-3 win over Andrey Rublev.
The winner between Fonseca and Menšík is set to face either No. 2 seed Alexander Zverev or No. 27 seed Rafael Jódar in the semifinals of the French Open.
