Swiss tennis star, Martina Hingis, has booked her place in the fourth round of the Australian Open following a convincing win over Germany's Barbara Rittner.

Hingis made light work of her German opponent, winning in straight sets 6-1, 6-0.

The world number three took just 46 minutes to dimiss Rittner, who threw her arms up to the sky after winning her only game of the match in the first set.

Hingis and Rittner are no strangers to one another. The two women have gone head-to-head five times with Hingis winning every time.

Coetzer challenge

The St Gallen player will now face South Africa's Amanda Coetzer in the fourth round, who made it through by beating Austria's, Barbara Schett 6-3, 6-3.

"Coetzer could be dangerous, but I am confident," explained Hingis after her third round match. "I think I'm very close to playing at my best. But nevertherless, I have learnt from the past and I shouldn't underestimate any player, no matter who they are."
