Mouratoglou: Emotional Struggles Cost Sabalenka US Open Title

The Technical Cost of Sabalenka's On-Court Frustration

Aryna Sabalenka's bid for another major title crumbled on the blue hard courts of Flushing Meadows, falling 6-4, 5-7, 6-2 to Elena Rybakina in the 2026 US Open final. The defeat did more than deny her a fifth Grand Slam trophy; it cost her the coveted World No. 1 position on the WTA rankings. According to renowned coach Patrick Mouratoglou, the root of the breakdown lies in Sabalenka's struggles with emotional management when the pressure mounts.

Mouratoglou contrasted her emotional outbursts with historical precedents, noting that while legends like John McEnroe channeled anger to elevate their execution, Sabalenka's frustration actively dismantles her technical baseline. When her temper flares, the clean strike zone vanishes. Instead of channeling that kinetic energy into her heavy topspin, she rushes her swing paths, leading to costly unforced errors at crucial break points. We saw similar structural cracks during her clay campaign, as noted in our analysis of her Roland Garros performance.

Rybakina Capitalizes on Hard Court Positioning

Tactically, Rybakina exploited these emotional lapses by keeping Sabalenka on the move, refusing to let her settle into her preferred central hitting zone. Standing deep behind the baseline, Rybakina absorbed Sabalenka’s pace and redirected the ball with flat, skidding groundstrokes. By extending the rallies beyond five shots, Rybakina forced Sabalenka to over-rotate on her forehand side, dragging her out of position and leaving the open court vulnerable.

This mechanical breakdown was particularly evident in the deciding set. As Sabalenka’s frustration grew, her first-serve percentage plummeted, allowing Rybakina to step inside the baseline and punish second serves. Rather than adjusting her court positioning to find safety, Sabalenka continued to redline her shots, a high-risk strategy that ultimately sealed her fate.

Rivalry Matchup & Player Profiles

Despite this latest setback, Sabalenka still holds a narrow 10-8 lead in their head-to-head rivalry. However, Rybakina's 6-4, 5-7, 6-2 victory in the 2026 US Open final marks a significant shift in the matchup dynamics, establishing the Kazakh as a major obstacle on fast hard courts.
