Jelena Ostapenko is out of the Australian Open, marking one of the first significant exits from a tournament that’s been largely free of surprises so far. Her early departure stands out even more in a draw where most of the top seeds have advanced without much trouble.

The first day of the third round has a number of intriguing matchups in both draws. The hard-hitting American, Frances Tiafoe, will face his toughest opponent yet in Aussie Alex de Minaur. Also, Coco Gauff will be tasked with taking on her fellow countrywoman, Hailey Baptiste, with a spot in the fourth round on the line.

Defending champion Madison Keys survived a stiff second-round challenge to beat fellow American Ashlyn Krueger 6-1, 7-5.

After a straight-set victory over Francesco Maestrelli on Thursday, the 38-year-old, 24-time major winner is just one shy of history.

Iva Jovic is enjoying a dream run at the Australian Open, next taking on top 10 player Jasmine Paolini. American sensation Jovic has already knocked her compatriot Katie Volynets and Priscilla Hon out of the Grand Slam.

Coco Gauff’s march into the Australian Open fourth round on Friday came without her most ardent supporter in her player's box — a deliberate family decision after her dad proved too wound-up to watch courtside.
