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

It's quarter-final time on Tuesday with plenty of big names in action, including:

• [1] Aryna Sabalenka v Iva Jovic [29]
• [3] Alexander Zverev v Learner Tien [25]
• [3] Coco Gauff v Elina Svitolina [12]
• [1] Carlos Alcaraz v Alex de Minaur [6]

However, it's set to be a scorcher in Melbourne, with temperatures possibly rising as high as 42C. Expect disruptions to play on the outside courts and a closed roof on Rod Laver Arena where the aforementioned matches are being played.

Henry Patten couldn't make it three British players in the men's doubles quarter-finals.

The second seed and his Finnish partner Harri Heliovaara lost in straight sets to Czech pair Petr Nouza and Patrik Rikl.

Nouza/Rikl will face Briton - and sixth seed - Neal Skupski and his American partner Christian Harrison in the quarter-finals. Luke Johnson and Jan Zielinski meet fourth seeds Marcelo Arevalo and Mate Pavic.

There are no British players left in the mixed doubles. Julian Cash, the third seed, and his Dutch partner Demi Schuurs led 4-1 in the opening set but lost 7-6 (7-3) 5-7 10-2 to Manuel Guinard and Kristina Mladenovic in the second round.

The men's and women's second seeds are safely through to the quarter-finals, both advancing in straight sets.

Defending champion Jannik Sinner beat Luciano Darderi 6-1 6-3 7-6 (7-2) but had a couple of wobbles in the third set. Iga Switek, meanwhile, beat Australian qualifier Maddison Inglis 6-0 6-3.

Defending women's champion Madison Keys bowed out in the fourth round. The ninth seed lost to fellow American Jessica Pegula - the sixth seed - 6-3 6-4.

Pegula will face fourth seed Amanda Anisimova, who beat Xinyu Wang in straight sets, in the last eight which guarantees there will be at least one American in the semi-finals.

Fifth seed Elena Rybakina is through to a Grand Slam quarter-final for the first time since Wimbledon in 2024 after beating Elise Mertens 6-1 6-3.

In the men's singles, fifth seed Lorenzo Musetti beat American ninth seed Taylor Fritz 6-2 7-5 6-4 to set up a quarter-final against 24-time Grand Slam champion Novak Djokovic, who received a walkover when Jakub Mensik withdrew.

Ben Shelton versus Casper Ruud is the final match on Rod Laver Arena.

American eighth seed Shelton enjoyed a productive 2025, bouncing back from only reaching the second week of one major the previous year with a semi-final in Melbourne and a quarter-final at Wimbledon.

Norwegian Ruud, the 12th seed, is enjoying his best run at a Grand Slam since the 2024 US Open and his best outing in Melbourne since 2021. The three-time Grand Slam finalist is eyeing a first major quarter-final since Roland Garros two years ago.

However, there's only room for one of them in the last eight at the Australian Open, with Jannik Sinner waiting for the winner.

Ruud currently leads their head-to-head 2-1 but they haven't played since March 2024 and Shelton hasn't dropped a set en route to the last 16.

Iga Swiatek speaking on court after reaching the Australian Open quarter-finals: "I felt pretty confident from the beginning. I felt like the pace of the ball was different to the last round, so I needed to adjust my legs and be really precise with my footwork. I'm really proud of my performance."

On whether she will treat herself to another crepe after today's victory: "Well I would only eat it after matches. Since I'm only playing night matches, suddenly I have no time. Unless maybe I go tomorrow, but I don't know what I'm going to do. It's going to be 42 Celsius right? Oh, it's 44 Celsius? Oh my god, I don't know what I'm going to do. I think I've still got to practice, right?

"But 44 degrees is crazy, I hope you guys [the crowd] will be fine watching the tennis and we will be fine playing!"

Jannik Sinner spoke after his victory: "It was very difficult, we are good firends off the court.

"I felt like in the third set, I had a couple of great chances and couldn't use them. I got very tight so I'm very happy I closed it in three sets.

"I tried to raise my level, I started off really well and at the end I had some pressure points. I am very happy, thanks for coming for and the support. It's amazing.

On his impressive serve: "We put a lot in to the serve and we changed the motion a bit. I feel more confident."

Sinner also spoke about other aspects of his game that he is working on, including improving his net game and becoming less predictable.

Ahead of his next match against either Casper Ruud or Ben Shelton, he says that he knows them both well - but the most important thing is his recovery from today's victory.

Maddison Inglis has nerves of steel, pass it on.

The Australian qualifier opens up a 40-0 advantage on her serve - possibly her most comfortable lead of the night - and manages to see it out at 40-30 after a lengthy cross-court backhand exchange.

Her Melbourne fairy-tale continues for at least one more game.

Over to you, Maddison Inglis!

The world number 168 steps up to serve to stay in this fourth-round match on Rod Laver Arena.

She might not have ever beaten a top-20 player in her career, but she will certainly give this a good go.

Jannik Sinner serves out wide and a sprawling Luciano Darderi can't get his backhand into the court.

Can he close out the win at the third attempt?

It isn't often you see Iga Swiatek come into the net, but when she does she is absolutely clinical.

Credit to Maddison Inglis though, who pushed the Pole all the way to deuce on serve. She is starting to find a bit of rhythm on strike in this fourth-round match.

Will it be too little too late, though?

Five consecutive points for Jannik Sinner. What a time to rediscover your forehand!

It's advantage Jannik Sinner as the players change ends. A backhand-forehand combination into opposite corners enable the second seed to rush the net and he buries the volley winner.

He leads 4-2.
