Two more Australian Open players have tested positive for the coronavirus, authorities revealed on Wednesday, taking to the number of cases linked to the tennis tournament to 10. It is the latest blow to preparations for the year's first Grand Slam in Melbourne - which has already be delayed by three weeks due to the pandemic. A string of infections detected by Australian authorities have forced 72 players to be confined to their hotel rooms 24 hours a day for two weeks. Victoria state police minister Lisa Neville said a total of four more people associated with the tournament had tested positive since Tuesday. "One of those is a player who has absolutely been in hard lockdown because he came in on one of the flights where we had positives," she told reporters.
