Jannik Sinner won the Australian Open title in 2024 and 2025
Jannik Sinner's ambitions of winning a third straight Australian Open title looked close to being over as the Melbourne heat crept towards 40C.
In the end, the rising temperatures helped the cramping Italian come through a testing third-round match - because the Grand Slam tournament's heat rule was invoked.
Only coming off court and having the roof pulled over saved Sinner from a shock defeat by American world number 85 Eliot Spizzirri.
"I got lucky with the heat rule," conceded Sinner, who came through to win 4-6 6-3 6-4 6-4.
