World No.2 Karolina Pliskova has continued her unbeaten summer down under to move into the second round of the Australian Open in Melbourne.
Pliskova overcame a second-set challenge from Kristina Mladenovic to see off the French Fed Cup hero 6-1 7-5 in one hour and 24 minutes on Tuesday.
The winner of the season-opening Brisbane International, second-seeded Pliskova could face former semi-finalist Coco Vandeweghe for a place in the third round.
Playing on a wildcard this year after an injury-plagued 2019 campaign, Vandeweghe faces German Laura Siegemund in one of 45 women’s matches on a bumper day two schedule.
Half of Monday’s matches were washed out, leaving officials trying to get through a back-log of first-round encounters.
British No.1 Johanna Konta, meanwhile, will not be repeating her 2016 charge to the semi-finals after crashing out with a 6-4 6-2 loss to crafty Tunisian Ons Jabeur.
It was a disappointing exit for 12th-seeded Konta, who made the semi-finals at Roland Garros last year as well as the quarters at Wimbledon and the US Open.
Ukrainian Dayana Yastremska, the 23rd seed and runner-up to Ashleigh Barty in Adelaide, continued her hot start to the summer with a 6-1 6-1 win over Slovenian qualifier Kaja Juvan.
The 19-year-old’s reward is a second-round shot at retiring 2018 Australian Open champion Caroline Wozniacki.
In other early results, Greek 22nd seed Maria Sakkari thrashed Russia’s Margarita Gasparyan 6-2 6-2 and Slovenian Polona Hercog set up a showdown with Barty with a 6-3 6-3 win over Swede Rebecca Peterson.
