Someone get Gavrilova a jacket

TENNIS: Viewers watching Australia's Daria Gavrilova play Swiss opponent Timea Bacsinszky might have thought they were seeing double on Saturday night.

In a match that made it difficult for viewers to tell the pair apart, the two stars took to Rod Laver Arena in identical attire.

Sharing the same sponsor meant that Gavrilova's light blue skirt and dark blue singlet was matched across the other side of the court by Bacsinszky.

Throw in the fact the pair are both right handers, and both have blonde hair, and it was quickly apparent that viewers were finding the going tough.
