Jessica Pagula knocked out ninth seed Madison Keyes in straight sets 6-3, 6-4 at Melbourne Park.

Reflecting on her win, Pagula says she felt strong going into the match against her close friend.

The six-seed Pagoula is still chasing her first Grand Slam title and enters the Final Eight in Melbourne for the fourth time.

Americans Coco Goff and Iva Jovic are also through to the women's quarterfinal.
