It's expected to be business as usual for the top seeds on day four of the Australian Tennis Open.
The world number one and top men's seed Rafael Nadal will play Roko Karanusic and is expected to have few problems advancing to the third round.
The fourth seed Andy Murray, fifth seed Jo-Wilfried Tsonga and sixth seed Gilles Simon are also on court today against much lower ranked opponents.
In the women's, the second seed Serena Williams will play Gisela Dulko of Argentina, while fourth seed Elena Dementieva is pitted against Iveta Benesova of the Czech Republic.
In the doubles, the New Zealand tennis number one Marina Erakovic will get the chance today to avenge her second round singles loss when she pairs up with Jelena Costanic Tosic.
They will play Lucie Safarova and her partner from Kazahkstan in the first round.
Safarova deated Erakovic in a thrilling three set singles match yesterday.
