Overview
- In her Madrid Open win over Zheng Qinwen, the live system called a serve an ace at 4-3 in the second set even though a ball mark on the clay appeared out.
- Rybakina pointed to the mark and confronted chair umpire Julie Kjendlie about the call.
- Kjendlie told her she could not leave the chair to check the mark and that protocol required her to accept the electronic decision.
- Rybakina recovered to win 4-6, 6-4, 6-3 to reach the last 16, then said she no longer trusts the technology because the TV graphic did not match any visible mark.
- Madrid uses full electronic line calling with no line judges or on-court mark checks, and repeat disputes like those involving Alexander Zverev and Aryna Sabalenka have renewed scrutiny of its reliability on clay.
