Emma Raducanu was left frustrated by her performance in Saturday's comprehensive loss to Iga Swiatek.

Five-time major winner Swiatek booked her place in round four of the Australian Open with a slick show of power at Rod Laver Arena.

The Pole won 6-1 6-0 and did not offer up a single break point to 2021 US Open champion Raducanu, who was playing in the third round at Melbourne Park for the first time.

And though Raducanu acknowledged Swiatek played at a high level, she was disappointed not to mount more of a test.

"Going into it, I knew I had to play really well when you're facing a top player," Raducanu told reporters.

"Credit to Iga, she played good tennis, but I think it was a little bit of her playing well and me not playing so well. That combination is probably not good and resulted in today. 

"She's a great player, moves really well, defends good. I just felt like certain aspects of my own game weren't necessarily firing.

"She played very well, but I also think that I didn't play very well. It's just not a great combination. 

"Of course, if a top player is playing perfectly, it's going to be a difficult match already. I just want to work on certain things and make them better and more consistent.

"The scoreline was obviously quite harsh. I feel like I look back and know exactly what I need to do, and I take it as feedback.

"I'm very clear on what happened out there. The scoreline reflects one thing. If I'm not necessarily able to hold my service games or kind of dictate, I feel like it seeps into the rest of my game. On my second serves, how the point is structured from then on, and also in the return games, you feel a lot more pressure."

Raducanu has been dealing with a niggling back problem, but the 22-year-old did not want to use fitness as an excuse.

"When I was in Auckland, at the end of last year, I was doing pool rehab," she added. 

"I think to be on a tennis court playing matches and competing is something I have to be grateful for. I started hitting when I came here 18 days ago. Yeah, I have to take a positive that I was able to beat two top opponents in the first two rounds.

"But no excuses of the back or physically. I didn't play well. She played very well."

Since 2019, when Swiatek made her WTA Tour debut, she is the only player with 20+ wins in four different events (Australian Open, Roland Garros, US Open and Italian Open).

In completed matches, Swiatek has now claimed 12.3% (28/227) of her grand slam sets by a score of 6-0 – only Margaret Court and Chris Evert have a higher rate in the Open Era (minimum 100 sets).

"I felt great," she said.

"I felt like the ball was listening to me... Today was kind of perfect for me."

Asked if she enjoyed being ruthless, Swiatek replied: "I don't take it personally, so I wouldn't say I'm ruthless.

"I just try to have the same kind of attitude and same kind of focus no matter what the score is. But it's not like I want to prove something. I'm just playing my game.

"If it's working, why stop? You always have to just keep going. It's not over until it's over."

Swiatek will next face Eva Lys, who is the first lucky loser to reach the fourth round of the women's singles at the Australian Open since the event moved to Melbourne Park in 1988.
