Elena Rybakina left the court uneasy after a contentious call in her Madrid Open quarter‑final against Zheng Qinwen. The Kazakh, down 30‑0 and 4‑3 in the second set, saw Zheng awarded an ace despite no visible mark on the clay. Rybakina appealed to umpire Julie Kjendlie, who refused to intervene, citing the electronic line-calling system. Her frustration echoed among peers questioning automated fairness.

Rybakina rallied, taking the final two sets 6‑4 6‑3 to clinch the match, but the disputed point left a bitter taste. She told officials, “The system is wrong, this is not a joke,” and added she “won’t trust it at all” after TV replays showed a clear discrepancy, raising doubts about umpire authority. The incident revives debate over Hawk‑Eye’s reliability on clay.

With the Madrid Open offering valuable WTA 1000 points, Rybakina’s win keeps her in contention for a top‑four seed at the upcoming French Open. Yet her public criticism may pressure tournament directors to review the technology’s deployment on slower surfaces. She meets a seeded foe. For now, the Kazakh remains focused on the next round, determined to let her game speak louder than any system.
