LONDON -- Top-seeded Jannik Sinner was treated by a trainer and left the court during the third set, seemingly surged in the fourth and then faltered again in the fifth, eventually losing to Daniil Medvedev 6-7 (7), 6-4, 7-6 (4), 2-6, 6-3 in the Wimbledon quarterfinals on Tuesday.
It was not immediately clear what was wrong with Sinner, who had his heart rate checked while sitting on the sideline before heading to the locker room. The 22-year-old from Italy returned after about 10 minutes and resumed playing, but lost the first game back at love.
