On a "red-warning" day of extreme heat in London, Jannik Sinner has dished out his own warning he's doing everything in his power to ensure he'll retain his Wimbledon title, returning successfully to action for the first time since being sensationally derailed at a sweltering French Open.
It was only a grass-court exhibition match at the prestigious Hurlingham Club, a 15-minute drive from Wimbledon, but world No.1 Sinner certainly looked in good nick as he defeated British No.1 Cam Norrie 6-3 6-3 on the sort of scorching day supposed to make life so uncomfortable for the pale Italian.
In the teeth of the hottest June day ever recorded in the UK -- temperatures were 33C (91.4F) on Wednesday and still rising in early afternoon - Sinner took to the court for his first match since his boilover second-round collapse from two sets and 5-1 up against Juan Manuel Cerundolo on May 28.
