Defending champion Jannik Sinner overcame a spirited challenge from Jan-Lennard Struff and soaring temperatures Tuesday to book his place in a third Wimbledon semifinal, moving one win closer to another Grand Slam final.
The world No. 1 was tested by the 36-year-old German, particularly in the opening two sets, but held his nerve to secure a commanding 7-5, 7-6 (7-4), 6-3 quarterfinal victory.
Sinner will face either seven-time Wimbledon champion Novak Djokovic or Canadian third seed Felix Auger-Aliassime on Friday as he bids to reach the seventh Grand Slam final of his career and his first of the year.
The Italian also passed another important test by coping well with temperatures of 30 degrees Celsius (86 degrees Fahrenheit) at the All England Club, a notable improvement after previous struggles in the heat, including his dramatic second-round collapse at this year's French Open, where he squandered a two-set lead and a 5-1 advantage before losing to Juan Manuel Cerundolo.
"Thanks for reminding me," the four-time Grand Slam champion joked when asked about the heat.
