World number one Carlos Alcaraz dropped just seven games in a routine win over Corentin Moutet while women's top seed Aryna Sabalenka also came through in straight sets against Anastasia Potapova, although she was taken to two tie-breaks.

Home favourite Alex de Minaur, the sixth seed, came through in straight sets against Frances Tiafoe, 25th seed Learner Tien downed Nuno Borges and fellow American Tommy Paul was 6-1 6-1 up when his opponent Alejandro Davidovich retired.

However, 13th seed Andrey Rublev - a former quarter-finalist in Melbourne - fell in straight sets to Argentina's 18th seed Francisco Cerundolo while Cameron Norrie lost to third seed Alexander Zverev in four to end British hopes in the singles.

Daniil Medvedev had to come from two sets down to defeat Hungary's Fabian Marozsan.

And there was an upset in the men's doubles, with British top seeds Julian Cash and Lloyd Glasspool falling in two sets to James McCabe and Li Tu.

In his post-match interview, Sascha Zverev reveals a deal he made with a journalist last year...

"If I win the Australian open, I will cut my hair." Zverev says.

"You [the journalist] decide my haircut, I will decide yours!"

Alexander Zverev wasn't happy with his serve but here are some of his statistics...

• 72% first serve and won 78% points behind his first serve
• 16 aces and one double fault
• Won 16/18 points on serve in the third set
• Five holds to love

Alexander Zverev was asked if he was happy with his victory: "Yeah, why not!

"To be honest, the last two matches were fantastic because they played really good tennis. Today, I think Cameron played the best match that we have played level-wise. I am happy to move forward and happy with the win.

"I actually thought I was serving bad but I was hitting my forehand quite big. That is the shot that is going to make me win or going to lose. If I feel confident in that shot and hitting it in that way, it's very important."

Cam came out with the right mindset, but Zverev showed why he is where he is in the rankings. He flicked the switch and the level went through the roof. From that point onwards, he was on a different level on the court.

Can Alexander Zverev get over the line?

Saved with an ace out wide. A handy weapon.

This isn't very clinical tennis from Alexander Zverev, firing a forehand long. Another break point for Cameron Norrie.

The break point comes and goes for Cameron Norrie.

Alexander Zverev is two points away from round four.

More bird excrement. More emergency mopping up. If you're in the crowd, I'd be wary of which towels the players are passing out at the end of the match...

Cameron Norrie levels the game at 30-all as Alexander Zverev sends a loose backhand into the tramlines.

And then another backhand error, this time from a drive volley. A bit of a needless shot.

Alexander Zverev is in complete disbelief as a serve from Cameron Norrie is called in. Replays show the call is correct. Zverev calls for another look. The ball is still in: 30-15.

Zverev overcomes the disappointment with a whipped forehand winner but is denied the bagel by a couple of backhand errors.

Zverev will be very happy in the end. He has found a very high level of tennis and managed to switch the mindset and the body language at the perfect time. This is only going to build confidence for him going further into the tournament.

If he can find this level this attacking style of tennis, he is a problem for anyone.

Ace. Ace. His 12th and 13th of the match.

Alexander Zverev is eyeing a bagel.

"Let's go Norrie, let's go" rings around the crowd.

"Yeah, nah" says Zverev, forcing an error. Deuce.
