Andy Murray vs Thanasi Kokkinakis LIVE: Australian Open latest scores, updates and results with Novak Djokovic in action

And Djokovic breaks through! Couacaud saved another break point with brave play from the baseline, taking on Djokovic in the rallies, but he was unable to serve it out. Djokovic came back and blasts his way past, producing the passing wnnner with Couacaud at the net.

But hold on… Couacaud limps back to his chair and suddenly has his head in his hands. He calls for the trainer and it looks like he rolled his ankle…

Djokovic holds to love and then comes from 30-0 on the Couacaud serve to bring up a very early break point chance. But Couacaud holds his nerve to save, before closing it out with a serve and volley! That should settle some nerves.

Novak Djokovic emerges out onto the Rod Laver Arena to another big ovation, where he will face the French qualifier Enzo Couacaud. It’s the biggest match of Couacaud’s life and he faces one of the biggest challenges in tennis: defeat Djokovic at the Australian Open. The nine-time champion has not lost a match here since 2018 and has won 22 in a row.

The night session is running behind schedule, but this will get underway very soon.

Claire Liu and Belinda Bencic have only just started their warm-ups on the Margaret Court Arena – so Andy Murray is facing a very, very late night.

So get this, one of these players will be playing in an Australian Open semi-final after a remarkable of day of results in the bottom half of the men’s draw:

• Alexei Popyrin
• Ben Shelton
• JJ Wolf
• Michael Mmoh
• Andy Murray or Thanasi Kokkinakis
• Brandon Holt or Roberto Bautista Agut
• Tommy Paul
• Jenson Brooksby

Roberto Bautista Agut is the top seed at #24, but he is 6-4 4-1 down to the American qualifier Brandon Holt!

The shocks continue on a stunning day at the Australian Open!

The lucky loser Michael Mmoh has shocked the former world No 2 Alexander Zverev 6-7 6-4 6-3 6-2!

The American wasn’t even supposed to have made the main draw but is now into the third round, where he will play JJ Wolf.

“I had my bags packed and my flights booked back to the US,” Mmoh said in his on-court interview. “Life is crazy. When you think everything is looking dark, there’s light at the end of the tunnel.”

Unbelievable! Alexei Popyrin picks himself up after failing to take a match point in the fourth-set tiebreak against Taylor Fritz and closes out a 6-7(4), 7-6(2), 6-4, 6-7(6), 6-2 win!

It’s a stunning upset for the Australian wildcard against the eighth seed American Fritz, and it has delighted the home crowd in an electric atmosphere on John Cain Arena.

“This win means so much to me,” says an emotional Popyrin. “I had the toughest year last year. I didn’t win many matches. I’ve won as many matches this year as I won the whole of last year, and it’s only January.

“I couldn’t have done it without you guys, you were incredible.

“Pre-season I put my head down and I worked as hard as I possibly could. I don’t want that feeling that I had last year ever again. … I love this feeling. I want more of this feeling. I want you guys to have this feeling more.”

Raw emotion from the 23-year-old Australian.

Enzo Couacaud (Fra) v (4) Novak Djokovic (Ser) – expected 8:30am

Marketa Vondrousova (Cze) v (2) Ons Jabeur (Tun) – expected 10:30am

Claire Liu (USA) v (12) Belinda Bencic (Swi) – expected 9am

Andy Murray (Gbr) v Thanasi Kokkinakis (Aus) – expected 10:30am

Adrian Mannarino (Fra) v (22) Alex De Minaur (Aus) – expected 9am

Caroline Garica marches on! The French number four seed won the big points at the big moments to win 7-6 7-5 in just under two hours on Rod Laver Arena. That was a proper battle, and Garcia had to save set points in the second set in order to progress against the 20-year-old. She was also down 2-5 in the first-set tiebreak.

“I felt the first set was a robbery, but I just tried to play one point at a time,” she says. Garcia is one to watch as she advances into the third round.

Rafael Nadal is expected to be sidelined for between six and eight weeks with the injury he suffered at the Australian Open on Wednesday.

The Spaniard’s reign as champion at Melbourne Park ended prematurely in the second round with defeat by American Mackenzie McDonald.

Nadal pulled up suddenly late in the second set and clutched at his left hip. He opted to finish the match after an off-court medical timeout but his movement was severely hampered.

The 36-year-old underwent a scan in Melbourne on Thursday morning that showed a grade two tear of his iliopsoas muscle.

An update from Nadal’s team said he would return to Spain for a period of rest and treatment, with the normal recovery time for the injury from six to eight weeks.

If that timeframe proves correct, Nadal could also miss the BNP Paribas Open in Indian Wells at the start of March but should be recovered in time for his favourite European clay-court swing.

Casper Ruud admitted a lengthy exhibition tour with Rafael Nadal may have compromised his Australian Open chances after joining the Spaniard in making an early exit.

A day after Rafael Nadal limped to defeat against Mackenzie McDonald, second seed Ruud was beaten 6-3 7-5 6-7 (4) 6-2 by another American, Jenson Brooksby.

The result means the men’s event has lost its top two seeds before the third round for the first time at any grand slam since here in 2002.

Ruud, a finalist at the French Open and US Open last year, had limited pre-season training after joining Nadal on a tour of Latin America lasting nearly two weeks.

The Norwegian said: “It’s very easy to sit here now and say that was bad for maybe both Rafa and I due to the fact that we lost early here.

“(The preparation) was maybe not enough to be able to perform well here this year. So it will be considered by me and my team what we will do in December this year, and if this was the right way to prepare for the Australian Open or not.

“Maybe it looks like it was not the right way, but there are many factors that come into play.”
