The US Tennis Association has cancelled several amateur events scheduled in August because of the coronavirus pandemic but is still planning to hold the US Open starting August 31. USTA National Championships in certain junior age groups for singles and doubles are being scrapped.

That includes boys’ 18s in Orlando and girls’ 18s in San Diego in singles; boys’ 16s in Rome, Georgia, and girls’ 16s in Mobile, Alabama, in singles; and boys’ and girls’ 12s through 18s doubles in Orlando. Men’s and women’s USTA National Grass Court Championships in Newport, Rhode Island, are also among the tournaments eliminated.

The USTA says “there was an inherent risk associated with hosting large numbers of individuals at one site, at one time, and would make risk mitigation difficult.” The group says the sort of COVID-19 testing and universal housing planned for the US Open “would logistically and financially be incredibly difficult to create” at these national events.

All sanctioned tennis has been suspended since March because of the pandemic. Competition is scheduled to resume in August.
