Image caption, Jannik Sinner is into the Wimbledon semi-finals for a third time ByEmily SalleyBBC Sport journalist Published 29 minutes ago Jannik Sinner moved a step closer to defending his Wimbledon title with a straight-set victory over Germany's Jan-Lennard Struff to reach the semi-finals.
The world number one has yet to hit his best form at the Championships but acted decisively in key moments to secure a 7-5 7-6 (7-4) 6-3 win over 74th-ranked Struff.
The Italian also showed no signs of being affected by the 30C temperatures, following his struggles with the heat in his shock second-round exit at this year's French Open.
Asked about struggling in the scorching conditions at Roland Garros, Sinner dryly responded: "Thanks for reminding me!
"We worked a lot after Paris trying to understand what went wrong and prepared in the best possible way.
"It was a huge test today.
I felt comfortable on the physical side, a good step forwards." Sinner could face Novak Djokovic next, in a repeat of last year's semi-final, if the 24-time Grand Slam champion beats Felix Auger-Aliassime later on Tuesday.
