Agnieszka Radwanska has said that she is "very happy" with her performance in the first round of this year's Australian Open.

The sixth seed eased into the second round with a 6-3 6-0 win over Japan's Kurumi Nara earlier, setting up a match against Johanna Larsson of Sweden.

The Polish player told reporters: "I think I really played well today. Maybe little bit slow start. Otherwise I think everything was working for me today. Very happy [with] my game.

"I don't know [why I started slowly]. I think couple things. Different court, first match. And just different [feeling] the ball. I just need, I guess, a few games to really play my game.

"I was really trying play aggressive, go down the lines. I think I was also serving good. I think the key also was the beginning of the second set, first tight games, and then I was able to break twice."

Radwanska reached the semi-finals in Australia for the first time last year.
