World No 2 Naomi Osaka will start her home Olympics against China’s Zheng Saisai after the draw was made for the Tokyo 2020 Games’ tennis tournament. Osaka has taken several months off for her mental health, but is considered the face of the Tokyo Games. Despite her profile and high chances of winning gold for the hosts, the IOC said last month that she has no obligation to speak to the press during the Olympics. World No 52 Zheng joined Osaka in skipping the All England Championships to concentrate on the Olympics, as did China’s No 2 Wang Qiang . Wang has been drawn against unseeded Paraguyan Veronica Cepede Royg. Second seed Osaka and Zheng open the Games on Centre Court on Saturday at the Ariake Tennis Centre. Osaka leads 2-1 in their career meetings, the most recent coming at last year’s Australian Open where the Japanese star won in straight sets. Zheng will also be in action in the doubles with Duan Yingying, with the pair facing Czech duo Karolina Pliskova and Marketa Vondrousova in the first round. Women’s singles top seed and reigning Wimbledon champion Ashleigh Barty meets Sara Sorribes Tormo, of Spain, in her Olympic debut. In the men’s draw, Serbia’s world No 1 Novak Djokovic faces Hugo Dellien, the Bolivian world No 139, in his opening game. The 34-year-old is going for a golden slam after deciding to play in Tokyo. The Wimbledon winner is looking to match Steffi Graf’s 1988 feat of winning all four slams and the Olympic singles in the same year. Elsewhere, two-time defending men’s singles champion Andy Murray will meet Canada’s ninth seeded Felix Auger Aliassime.
