Emma Navarro calls for rule change after Australian Open loss to Iga Swiatek - A double bounce call against Swiatek was missed by the umpire in her 6-1 6-2 victory.

Iga Swiatek continued her romp through the Australian Open draw with a quarter-final victory over Emma Navarro. The Pole's 6-1 6-2 win means she has dropped just 14 games so far in five matches - a feat bettered under the current format by only Maria Sharapova, Monica Seles and Steffi Graf.
