Proof of Covid-19 vaccinations are mandatory for adult US Open spectators but not for players – and that’s something Victoria Azarenka finds “bizarre.”

Azarenka, a two-time Australian Open winner and three-time US Open runner-up from Belarus, told fans after her victory Wednesday she was glad they were all vaccinated for the deadly virus, a requirement mandated by New York City officials.

“I want to start this conversation between our players, because to me it’s a bit bizarre that fans have to be vaccinated and players are not,” Azarenka said.

“In my opinion, it’s inevitable that it will be mandated at some point. I don’t see the point of stalling it, because I think we all want to be safe, to continue doing our jobs and I know there is a lot of discussions about it.”

The WTA says nearly half its players are vaccinated while the ATP says just over half its players are vaccinated.
