Overview
- Sinner suffered a sudden collapse at Roland Garros in June after leading Juan Manuel Cerúndolo by two sets and 5-1, then lost the match as he experienced severe dizziness.
- He underwent comprehensive cardiac and metabolic tests at Milan’s San Raffaele Hospital that were reported to show no medical abnormalities.
- The world No. 1 skipped traditional grass warm-up events, arrived early in London and has started on-court practice at the All England Club with a planned exhibition at the Hurlingham Club for match simulation.
- Concerns persist because Sinner has lost all nine career matches lasting more than three hours and 50 minutes, and former Olympic champion Monica Puig said the recent episodes should sound alarm bells for his team.
- Sinner enters Wimbledon as the defending champion and top seed with an otherwise dominant 2026 season, a combination that raises focus on how his preparation and fitness will affect his title defense and year-end No. 1 bid.
