 Former champion Andy Mori has been added to the main draw of the US Open following the withdrawal of Stan Waringka. Mori has had a tough year having missed the Australian Open because of a positive Covid-19 test and opting out of competing at the French Open. He reached the third round at Wimbledon but withdrew from the men's singles tournament at the Tokyo Olympics on the advice of his medical team. The US Open runs from August 30th to September 12th.
