World number one Iga Swiatek had no problem dealing with Camila Osorio during Wednesday's second round, advancing with a 6-2 6-3 victory.

Swiatek, 21, is seeking her fourth grand slam title and her first at the Australian Open, having already won the French Open twice before claiming her first US Open crown this past season.

Against Osorio, it was Swiatek's ability to consistently return that was the difference, holding the Colombian to just a 31 per cent success rate on her service points in the opening set (eight-of-26).

It resulted in a lightning-quick start for the Polish superstar, winning the first four games of the match, and despite giving back a couple breaks of serve, Swiatek did not allow Osorio to hold serve a single time in the opening frame.

Osorio was able to finally hold serve to begin the second set, before Swiatek again rattled off four consecutive games to collect a double-break and a winning lead.

In a remarkably clean performance from the tournament favourite, Swiatek landed 80 per cent of her first serves fair while committing no double faults, and both players finished with more winners than unforced errors.

With the victory, Swiatek will now face the winner between Cristina Bucsa and Bianca Andreescu in the third round.

Data Slam: Swiatek in legendary company

Swiatek has now won 53 of her first 65 grand slam matches – the sixth-best total through 65 attempts in the Open Era.

She trails only Margaret Court (61), Monica Seles (60), Chris Evert (57), Martina Hingis (56), Billie Jean King (56) and Tracy Austin (54).
