Jornal Do Brasilia - Murray, Djokovic to defy aches and pains at Australian Open

It remains to be seen how much the 35-year-old Murray has left in the tank after he made round three by winning a five-set marathon which ended at 4:05 am on Friday.

The unseeded former world number one, who also played five sets in his opener at Melbourne Park, will need to defy tiredness and his metal hip against 24th seed Roberto Bautista Agut.

The three-time Grand Slam champion Murray, whose career looked over a few years ago because of his hip injury, took five hours and 45 minutes to defeat Australia's Thanasi Kokkinakis.

Murray was back at Melbourne Park practising just eight hours after his late night, and the 66th-ranked Briton will need all his trademark battling qualities against his Spanish opponent.

Murray's old rival Djokovic is clear favourite to win the Australian Open for a record-tying 22nd Grand Slam, but there are concerns about his left hamstring.

The Serb faces a potentially tricky test against 27th seed Grigor Dimitrov.

Following a four-set victory over French qualifier Enzo Couacaud on Thursday, the 35-year-old admitted he cannot practise between matches.

He needed a medical timeout and had heavy strapping around his thigh.

"I am worried, I have reason to be worried," Djokovic said of an injury he has been carrying since before coming to Melbourne.

"My situation with my injury is not ideal... I have to take it day by day.

"I'm not practising in the days between because I'm trying to give myself more time for my leg to be in somewhat more of an ideal state."

With defending champion Rafael Nadal and last year's beaten finalist Daniil Medvedev both out, plus world number one Carlos Alcaraz missing with injury, the title is Djokovic's to lose.

In other third-round matches, fifth seed Andrey Rublev of Russia faces British 25th seed Dan Evans.

Exciting Danish teenager Holger Rune is also in action, the ninth seed up against France's Ugo Humbert.

Aryna Sabalenka and Caroline Garcia headline the women's matches on day six of the first major of the year.

France's fourth seed Garcia should have too much for unseeded Laura Siegemund of Germany.

Hard-hitting Belarusian Sabalenka, the fifth seed who has looked imperious so far, faces a test in the form of 26th seed Elise Mertens.

Also playing is Olympic champion and 12th seed Belinda Bencic.

She goes up against unseeded Italian Camila Giorgi.
