Overview
- Sinner collapsed during a Roland Garros match after leading by two sets and 5-1 and earlier showed severe dehydration at the Australian Open, events that prompted medical follow‑up.
- Reporting says he underwent confidential, in‑depth cardiac and metabolic checks at Milan’s Raffaele Hospital, but full results have been kept private by his team.
- Sinner told reporters he and his staff “came to a conclusion which is very good” after testing and said they altered his workload to test how his body reacts in warmer conditions.
- He skipped traditional grass warm‑up tournaments, practised in warmer settings, and won an exhibition at Hurlingham without obvious dehydration, yet rivals and commentators still question his stamina in long matches.
- The episodes have sharpened focus on heat, scheduling and player safety and could change how top players prepare for hot conditions and how tournaments manage heat risk going forward.
