Iga Swiatek is growing in confidence by the day after she blew Cristina Bucsa to reach the fourth round of the Australian Open.

The world number one ruthlessly dispatched the Spanish qualifier 6-0 6-1 in just 55 minutes on Margaret Court Arena on Friday.

Swiatek won the French Open for a second time last year before claiming her first US Open title and the 21-year-old is the favourite to be crowned champion at Melbourne Park.

Reflecting on her progress through the draw so far, the Pole believes she is making great strides in her quest for a fourth grand slam triumph.

"I feel I'm more and more confident since day one here," she said. "I feel like I've done so much work to feel more confident, more relaxed on court.

"I'm pretty happy I did it because it's just a little bit easier. Whe you actually play those matches, you can feel the rhythm a little bit more.

"I don't feel like the tournament is going to start now, because first rounds are always challenging.

"I'm trying to treat every match separately. I always try to have the same mindset. I can just say that I feel more confident because I'm played a couple of matches here."

Swiatek will do battle with Elena Rybakina in the fourth round and will ensure she does her homework before facing the Wimbledon champion.

"Tactically, I'm not prepared yet. We played an exhibition in Dubai, [but] it's hard kind of to take a lot from that match," she said.

"I'm pretty sure my coach is going to be ready to give me some tips. We'll see [but] I'm not really thinking about that today."
