MELBOURNE, Australia (AFP) — Eight-time champion Novak Djokovic was made to sweat at the Australian Open yesterday as Serena Williams made serene progress in her bid for a record-equalling 24th Grand Slam title.

Women’s favourite Naomi Osaka also charged through, but fellow major winners Stan Wawrinka, Bianca Andreescu and Petra Kvitova were all second-round casualties.

Among the late matches, Aussie crowd-pleaser Nick Kyrgios served underarm, smashed a racquet and rowed with the chair umpire before coming from behind to beat France’s Ugo Humbert in five gripping sets.

Earlier, Djokovic was given a stern examination by American Frances Tiafoe, and dropped his first set of the tournament before recovering to win 6-3, 6-7 (3/7), 7-6 (7/2), 6-3.

“I was fortunate to get through the third set today, it was anybody’s game,” said the defending champion, after his win in hot conditions in Rod Laver Arena.

The top seed looked in control after taking the first set, but lightning-quick Tiafoe, who reached the quarter-finals two years ago, refused to go away.

The American bounced back to take a close second set, but imploded as tensions rose in the fourth, receiving a code violation for an audible obscenity as Djokovic took charge.

The Serb is targeting a record-extending ninth title, and his 18th Grand Slam trophy overall as he snaps at the heels of Rafael Nadal and Roger Federer, who top the all-time list with 20 each.

Dream result

Djokovic avoided the fate of 2014 winner Wawrinka, who blew three match points in the fifth-set tie-breaker of his four-hour epic with Marton Fucsovics, who won 7-5, 6-1, 4-6, 2-6, 7-6 (11/9).

“I hesitated a little bit when I had the match point and I lost it,” said the 35-year-old Swiss, a three-time Grand Slam winner.

Osaka, whose three Grand Slam titles include the 2019 Australian crown, had no such trouble in her evening match against France’s Caroline Garcia, despite fearing defeat after a bad dream.

“Last night I had a dream that I lost this match, and I really didn’t feel good about it,” she said after the 6-2, 6-3 win.

Second seed Simona Halep survived a scare when she reeled off five third-set games in a row to avoid defeat by Australia’s Ajla Tomljanovic.

“I fought till the end. I never gave up during the match, and that’s why maybe I could win in the end,” said the two-time Grand Slam winner.

Williams, 39, continued her quest to equal Margaret Court’s all-time mark of 24 Grand Slams with a 6-3, 6-0 romp past 99th-ranked Serbian Nina Stojanovic.

Williams hit 27 winners in her 101st Australian Open match, while again sporting her unique, one-legged catsuit inspired by track legend Florence “Flo-Jo” Griffith Joyner.

“I’m here to have fun, and it’s great to be playing in front of a crowd,” said Williams.

With Australia virtually virus free, the tournament is welcoming the biggest Grand Slam crowds since the pandemic, although attendances are well down on previous years.

Lost for words

A socially distanced John Cain Arena was rocking for the Kyrgios match, where the unseeded home favourite denied Humbert what seemed like a certain win to set up a clash with US Open champion Dominic Thiem.

“Honestly, I don’t know how I did that,” said Kyrgios after the unlikely 5-7, 6-4, 3-6, 7-6 (7/2), 6-4 victory.

“I don’t even know what to say, I’m lost for words. That is one of the craziest matches I’ve ever played.”

German sixth seed Alexander Zverev went through in less compelling fashion grinding past America’s Maxime Cressy 7-5, 6-4, 6-3.

Williams’ elder sister Venus, 40, was among the casualties on day three when she painfully rolled her ankle in the first set against Sara Errani before hobbling through a 6-1, 6-0 defeat.

And Andreescu, the 2019 US Open champion, who missed the entire 2020 season with a knee injury, saw her comeback come to an abrupt end 6-3, 6-2 against Taiwan’s Hsieh Su-wei.

Elsewhere Kvitova, the former Wimbledon champion and Melbourne runner-up in 2019, committed 44 unforced errors in her 6-4, 1-6, 6-1 defeat to Romania’s Sorana Cirstea.

However Thiem, runner-up to Djokovic last year, was all smiles as he beat Germany’s Dominik Koepfer 6-4, 6-0, 6-2.

Eighth seed Diego Schwartzmann of Argentina beat France’s Alexandre Muller 6-2, 6-0, 6-3, while Canada’s Milos Raonic won 6-7 (1/7), 6-1, 6-1, 6-4 against another Frenchman, Corentin Moutet.
