American Marconi Wireless News - Jabeur, Wozniacki derailed by Russian NextGen at Australian Open

The veteran pair were no match for Mirra Andreeva and Maria Timofeeva, who emphatically stamped their mark on the opening Grand Slam of the year, which was marred by rain on day four.

Andreeva, just 16, was in scintillating form to take down 29-year-old three-time major runner-up Jabeur 6-0, 6-2 under the closed roof on Rod Laver Arena in just 54 minutes.

"Probably it was the best match (ever)," said Andreeva, a schoolgirl who burst onto the scene when she reached the fourth round at Wimbledon last year as a qualifier.

"The first set, I didn't expect that I would play this good. Second set was also not bad. So, yes, for me it was an amazing match."

Her reward is a third-round clash against either France's Diane Parry or fellow Russian Kamilla Rakhimova.

Timofeeva, a 20-year-old qualifier, was equally impressive against 2018 champion Wozniacki, who flew through the first set and was a break up in the second.

Undeterred, Timofeeva, showing impressive power, hauled herself back into the contest and ultimately prevailed against a player 13 years her senior, winning 1-6, 6-4, 6-1.

"It was an honour to play here against Caroline today. I'm just beyond happy and couldn't ask for more," she said after setting up a third-round meeting with fellow qualifier Russian Alina Korneeva or 10th seed Beatriz Haddad Maia.

With play on outside courts starting more than three hours late due to rain, fourth seed Jannik Sinner was one of the fortunate few to be scheduled in one of the three main arenas, which all have roofs.

The fourth-seeded Italian wasted no time in dispatching Dutch qualifier Jesper de Jong 6-2, 6-2, 6-2 on Margaret Court Arena.

His next assignment in his bid for a maiden Grand Slam title will be against Argentine 26th seed Sebastian Baez or Colombia's unseeded Daniel Elahi Galan.

- 'It is what it is' -

Djokovic headlines the night session on centre court against home hope Alexei Popyrin, while fellow defending champion Aryna Sabalenka faces her second consecutive qualifier.

Serbian superstar Djokovic dropped a set against unheralded Croat Dino Prizmic in his opening clash and will not want to do repeat the feat against 43rd-ranked Popyrin.

But the 10-time Australian Open winner heads into the match with lingering concerns over his health after admitting he was "a bit under the weather" against Prizmic.

"Look, it is what it is. You just have to try to deal with it and get over it and accept the circumstances and try to make the most of it," he said.

Should he come through, the world number one will face a third-round clash against veteran Frenchman Gael Monfils or Argentine Tomas Martin Etcheverry, who ended Andy Murray's tournament.

Sabalenka will be on court ahead of Djokovic to face Czech Brenda Fruhvirtova.

The powerful Belarusian second seed dropped just one game in obliterating her first-round opponent, with Fruhvirtova set to face more of her wrath.

US Open champion Coco Gauff, last year's finalist Stefanos Tsitsipas, and fifth seed Andrey Rublev are also in action.
