Australian Open 2023 LIVE updates: Daniil Medvedev, Stefanos Tsitsipas, Jeļena Ostapenko in action on day five as third round begins

Neroli Meadows is joined by John Fitzgerald to review a crazy evening at Melbourne Park featuring a late night Andy Murray classic, Djokovic battles injury and hecklers, plus amazing scenes as two home-town heroes advance to round 3. Wally Masur jumps on board to preview all the day 5 action.

Two Australians remain in the singles draw. De Minaur clinched his second-round win over Adrian Mannarino in four sets, but the match that came beforehand was the true Aussie underdog blockbuster.

Alexei Popyrin took down eighth seed Taylor Fritz in five sets, stunning the American, thrilling the crowd, and stealing the hearts of those who watched the emotional 23-year-old in the post-match interview.

Disappearing into his shirt, shedding tears and hugging interviewer Casey Dellacqua, Popyrin clearly just couldn’t believe he’d done it.

Here’s how the Australians have fared in the tournament.

Tennis Australia chief executive Craig Tiley believes there is little Australian Open organisers can do to avoid finishes like the 4am conclusion to Andy Murray and Thanasi Kokkinakis’ second-round match earlier this morning.

Tiley told Today the combination of requiring multiple night matches for broadcasters and weather delays for extreme heat and rain in the first four days of the event set the stage for the late finish which was exacerbated by the six-hour match which began soon after 10pm Thursday.

Tennis legend Martina Navratilova tweeted this morning that the sport needed better rules for weather and for start and cut-off times.

“It is extremely difficult,” Tiley told Today.

“There are so many variables. Over the last few days we have had extreme heat, we’ve had over five breaks of rain, we’ve had cold and those are…it’s Melbourne but don’t often get those conditions in such a short period of time.”

The Australian Open has always had matches which finish late including last year’s men’s final which was won by Rafael Nadal after five long sets and Tiley said it was hard to account for which contests could run long and which run to time.

“We’ve had three late nights with scheduling trying to catch up with matches but generally a women’s match is about an hour and a half and a men’s match is a little over two and a half hours, that’s majority of the length of matches and you work your schedule around that,” Tiley said.

“Then you are going to have an out-of-the-box situation where, like last night, it goes extra long unexpectedly.

“That happens every year. There is always one that goes five or six hours and it is hard to schedule the entire event around the potential that happens one time.

“You’ve also got to protect the matches. If you just put one match at night and there’s an injury you don’t have anything for fans or broadcasters.

Tiley also pointed out that players like Kokkinakis and women’s star Jessica Pegula were highly rated in both singles and doubles so played in multiple events at the Open, further straining their schedule.

“They choose to play extra events, there is always going to be a situation where you have to back up quickly,” Tiley said.

“At this point, there is no need to alter the schedule. We always look at it when we do the debrief like we do every year, at this point we’ve got to fit the matches in the 14 days so you don’t have many options.”

Nick Kyrgios sent a message of support to his championship doubles partner Thanasi Kokkinakis after a comeback from Andy Murray in the early hours dashed Kokkinakis’s Australian Open hopes.

Kokkinakis posted a frustrated tweet in the aftermath of the match (“This f—ing sport man”), which Kyrgios retweeted, adding “Love you brother, u number 1 in my eyes”.

The top Australian player, who withdrew from the tournament with a knee injury, added another message of support this morning.

It was a bizarre tournament for Kokkinakis. His first match with Fabio Fognini was split over two days thanks to extreme heat and an evening downpour. The match started on Tuesday but the weather delay forced the pair to wait until Wednesday to finish it off, which Kokkinakis did in three minutes.

Then his post-match interview went viral when a reporter accidentally called him Nick.

At 4.05am, after nearly six hours, Andy Murray won one of the greatest Australian Open matches of all time. One of the greatest matches that barely anyone saw.

In a triumph of absurd timing that embarrassed the sport, the former world No.1 defeated Australia’s Thanasi Kokkinakis in the second-latest finishing grand slam match in the history of the tournament.

It might have been the greatest comeback of Murray’s career – it was certainly the longest – but it was witnessed by a precious few.

At 35, with a tin hip and down two sets and break points in the third, he found a way to fight back and win just as it seemed the game would run into breakfast TV.

“Look, it’s obviously amazing to win the match, but I also want to go to bed now,” Murray said.

“I’m like, you know, it’s great, but I want to sleep.”
