The BBC Sport team in Melbourne will be rounding up every day of play with a daily podcast during the Australian Open.

Head to BBC Sounds to find all episodes. Today's edition will be available shortly after play concludes.

Cameron Norrie is the only British player left in either the men's or women's singles at this year's Australian Open.

He came through a rain-affected four-set win over American Emilio Nava on Wednesday and next he will play third seed Alexander Zverev, who was beaten in last year's final.

The German has won all six of their previous meetings at tour level, although Norrie was only beaten in a fifth-set tie-break by Zverev in the last 16 of this tournament two years ago.

Norrie is scheduled to be on court at about 07:30 GMT on Friday and you'll be able to follow that match with us.

Also on Friday - in the very early hours UK time - top seeds Carlos Alcaraz and Aryna Sabalenka are in third-round action.

Earlier today, 10-time champion Novak Djokovic was a straight-set winner against Francesco Maestrelli.

Here are some of the highlights of his second-round win:

Asked about her jellyfish-inspired outfit, Naomi Osaka replied: "For me, this is just something fun that I like to do on the court. I don't really talk that much, but I like to express myself through clothes and I'm really glad that you guys loved it."

On her next outfit: "Well I have to make you tune in somehow, so I'm not going to tell you."

Plenty of top seeds have made it safely through to the third round today.

Jannik Sinner, Novak Djokovic, Lorenzo Musetti and Ben Shelton all won in straight sets in the men's draw, while Naomi Osaka, Amanda Anisimova and defending champion Madison Keys were among the victorious players in the women's draw.

And 40-year-old Stan Wawrinka, in his final Australian Open appearance, created one of the main stories of the day. The 2014 champion won a deciding-set tie-break against French qualifier Arthur Gea to set up a third-round match against ninth seed Taylor Fritz.

As Naomi Osaka mentioned there, this is Sorana Cirstea's last Australian Open.

The 35-year-old announced last month that she would retire from tennis at the end of 2026 after 20 seasons on the WTA Tour.

Naomi Osaka, speaking about what it took to get through a three-set match against Sorana Cirstea: "Apparently a lot of 'come ons' that she was angry about.

"I tried to play well and I think I hit a lot of unforced errors, but I tried my best. She's a great player, I think this was her last Australian Open, so sorry she was mad about it."

Asked if Cirstea complaining about Osaka pumping herself up between the Romanian's first and second serve was a problem, the 16th seed replied: "I think so, but like she could have asked me."

Naomi Osaka will face Australian qualifier Maddison Inglis, the world number 168, in the third round.

This was Inglis' reaction to winning her second-round match against Germany's Laura Siegemund earlier...

Sorana Cirstea gave a very frosty handshake to Naomi Osaka at the net and then started arguing with the former world number one.

Osaka seems a bit confused about it, but she clears it up in her on-court interview, saying Cirstea told her there were "a lot of 'come ons' that she was angry about".

Two-time Australian Open champion Jannik Sinner, speaking in his on-court interview: "Every match is very difficult so I'm very happy to be in the next round. I was returning well, my serve was really good, so I'm happy with my performance.

"I feel like I'm in good shape at the moment. Depending on how matches go and how long I stay on court, we will decide the work to do the next day. I know how much work I've put in so the body feels good and the mind is in a good moment.

"It is a very special tournament for me and it has been a special court for me in the past years, so let's see what's coming this year."

On trying to add more variety to his game, he said: "Drop shots on the backhand side we still need to work on because some don't arrive at the net. We are working on that. We try to prepare every match in the best possible way. I am happy with where I am but we will keep pushing.

"I think we all know who has the best drop shots [on tour], it's Carlos [Alcaraz] of course. There are some great talents who are in front of me in that aspect."

On facing Eliot Spizzirri next: "I've been watching him also last year a little bit, very aggressive on the court and a big server also. I don't know him as well because we haven't played yet but I'm hoping for a great match."

"Come on!" shouts Naomi Osaka as she belts down a forehand winner to bring up two match points.

She gets it! Naomi Osaka is one game away from the third round. Can she serve it out?

You have to feel a bit for Sorana Cirstea. She was ploughing on in that last service game before the umpire interrupted and told her off for something. She seemed to lose all sense of concentration after that.

Sorana Cirstea pulls ahead, but Naomi Osaka keeps dragging her way back into the game and all of a sudden the world number one has a break point.

If she gets this, then surely her place in the third round is almost secured.

After whacking her racquet off the court, Naomi Osaka blasts a forehand winner past Sorana Cirstea before forcing her way to deuce.

Another winner flies off her racquet, but she has to go the long way round before eventually sealing the hold.

A brilliant return sets Jannik Sinner up for a finish as he edges to 15-30 and within two points of victory.

But credit to James Duckworth, who doesn't give it up and offers his loyal home support another game to cheer as he wins three straight points to hold and force Sinner to serve this out.

Here's a half chance for Sorana Cirstea. She takes advantage of Naomi Osaka's second serve and makes the former world number one pay as she opens up a 0-30 lead.

Osaka switches things up and goes to the net for the next point, putting it away before landing her 40th unforced error of the match.

Break back points for the Romanian.

Jannik Sinner is a game away from the third round!

James Duckworth misses the line to concede at 40-15, before he steps up to serve for potentially the last time at this year's Australian Open.

Naomi Osaka rants to herself after failing to lift a simple backhand over the net, and then does the exact same thing on the next point to give Sorana Cirstea the hold.

The two-time Australian Open winner needs to be careful that she doesn't allow Cirstea to find a way back in.
