Iga Świątek's run hasn't been without controversy, including one call in her quarter-final win over Emma Navarro that left the tennis world scratching their heads.

Emma Navarro called for a change in the rules after a controversial moment during her Australian Open quarter-final loss to Iga Swiatek. The second seed continued her romp through the draw with a 6-1 6-2 victory to set up a meeting with Madison Keys.

Eva Lys had already booked a flight home after initially failing to qualify for the Australian Open — but scored a second shot at competing after a “lucky loser” spot opened up.

But Gauff was upset in the Australian Open quarterfinals by No. 11 Paula Badosa of Spain. On the men’s side, Italian Jannik Sinner is the defending champion and No. 1 seed. Sinner is playing while awaiting a Court of Arbitration for Sport verdict of a World Anti-Doping Agency appeal of his doping case.
