Iga Swiatek has stepped up her game to restore order with a more routine Australian Open second-round win at Melbourne Park.
The world No.1 advanced to the last 32 on Wednesday with a resounding 6-2 6-3 victory over Colombian Camila Osorio.
Swiatek had to scrap her way back from a service break down in the second set of her less than convincing Open opener against Jule Niemeier on Monday night.
That was the Pole's first outing since suffering a crushing loss to world No.3 Jessica Pegula at the season-opening United Cup before withdrawing from the Adelaide International 2 with a shoulder issue.
The reigning French and US Open champion was still below her brilliant best for periods against Osorio, dropping serve three times, but at least looks to be slowly warming to the task as the Melbourne Park title favourite.
Swiatek raced to an early 4-0 lead and broke the South American six times in taking the match in one hour, 24 minutes under a closed roof on Rod Laver Arena.
The straight-sets victory set up a third-round meeting on Friday with either Canada's unseeded former US Open champion Bianca Andreescu or Spanish qualifier Cristina Bucsa.
Third-seeded Pegula is next up on RLA against Belarusian Aliaksandra Sasnovich.
Other leading seeds scheduled for action on day three include Maria Sakkari, Coco Gauff, Madison Keys and 2022 runner-up Danielle Collins.
But with more rain in Melbourne again delaying play on the outside courts, some big guns will have to wait before starting their second-round matches.
