Italy's Matteo Berrettini, the 2021 Wimbledon runner-up and a title favourite this year, pulled out of the tournament on Tuesday after testing positive for coronavirus. "I am heartbroken to announce that I need to withdraw from @wimbledon due to a positive COVID-19 test result," the 26-year-old Italian wrote on Instagram. Berrettini was widely regarded as one of the biggest threats to defending champion Novak Djokovic at the All England Club, having captured back-to-back grass-court titles in Stuttgart and Queen's.
