They may end up playing some of these tournaments with no spectators, which is what NCAA basketball is contemplating. IW is coming right up, and California has the 2nd most cases in the US. I know sensible people who are contemplating canceling plans to fly within the US this coming week, and what do tennis players do all year long? They fly around the world on airplanes. You wonder if it's safe for them, and if it's safe for cities/countries hosting these events to introduce them in. SXSW festival in Austin (huge music/film/tech event) was just postponed because the Mayor of Austin deemed it unsafe to bring loads of people into his town right now. Unless something changes drastically, I don't see the Italian Open happening, at least in Italy. France and Germany also have a pretty high number of cases. Spain has not so many now, and could host some clay events, but they are already considering canceling large public events.
