A disputed line call during the second-set tiebreak altered the outcome of Joao Fonseca's match against Casper Ruud at the 2026 French Open. Andy Roddick criticized the tournament's refusal to adopt electronic line calling. Tournament director Amelie Mauresmo defended the use of human officials.
The incident occurred in the second-set tiebreak with Ruud leading 8-7. A call of 'Out' from the stands distracted Ruud, but chair umpire Louise Engzell ruled the ball in after review, giving the point to Fonseca. Broadcast replays later showed the ball had landed out. Fonseca won the match 7-5, 7-6(8), 5-7, 6-2 after taking the second and fourth sets.
