We're going to say goodbye to you here but we'll still have commentary in this page of Alexander Zverev's first-round match against French wildcard Lucas Pouille and you can keep up to date with all the live scores and results across the website.
We're back tomorrow for a busy old day in Melboune.
See you then!
It's been a day heavily affected by rain in Melbourne with play not getting under way on the outside courts until just a couple of hours ago.
There have been wins for Casper Ruud, Mirra Andreeva, Zheng Qinwen and defending champion Aryna Sabalenka but Sonay Kartal became the first Brit to fall at her debut Australian Open.
Alexander Zverev takes on Lucas Pouille on Rod Laver shortly.
Sabalenka 6-3 6-2 Stephens
Two-time defending champion Aryna Sabalenka speaking on court: "Thank you guys. I'm super happy to be back. I love this place and we have a full stadium, I mean I couldn't dream for more. Thank you so much for coming and supporting us. I really enjoy playing in front of you every time."
On how she felt on court: "It was a tough match. They are always tough matches against her. I don't feel like I played my best probably but I'm glad that I managed to close this match in straight sets."
On returning to Melbourne Park: "It definitely feels like home."
Sabalenka 6-3 6-2 Stephens
Not perfect from Aryna Sabalenka but it's a victory nonetheless.
She's now being forced to partake in a little dance on court and to be honest, she looks mortified.

Stephens did what she could here really, except for those first three games in the first set, but it has been a very confident performance from Sabalenka.
I was a little bit surprised with Stephens' approach in the first few games.
You haven't won a match in a long time, you are playing the number one in the world, at least show a lot of energy in-between the points and try to make the match physical, if nothing else.
Sabalenka 6-3 6-2 Stephens
Aryna Sabalenka makes a winning start to her title defence, navigating a tricky match against Sloane Stephens and sealing it when the American's forehand goes narrowly wide.
The world number one is into the next round of the Australian Open.
Three-peat on?

Aryna Sabalenka gets out to 30-0 on serve but then double faults as she tries to close out the match.
Few nerves from the defending champ?

Sloane Stephens asks the question of Aryna Sabalenka, winning just her second game of the set and forcing the Belarusian to serve it out.

That shot is definitely going to be on the highlights reels!
What an incredible get from Sloane Stephens.
*Sabalenka 6-3 5-1 Stephens
Sloane Stephens has the crowd in the palm of her hand as she somehow bats back Aryna Sabalenka's smash volley and forces the error from the defending champion.
But it's an otherwise uneventful game for Sabalenka as she takes another straightforward hold and will now serve for the match.

Aryna Sabalenka drops to the ground as she leaves Sloane Stephens' forehand, thinking it's heading out of bounds, but it turns out to be a brilliant shot from the American and Sabalenka can't believe she left it.
Stephens saves a break point but Sabalenka brings up another with a brilliant shot down the line then forces the error from Stephens to take the double break.

Aryna Sabalenka firmly has the momentum back on her side as she consolidates that break of serve with a straightforward hold to 15.
Kartal 1-6 6-7 (5-7) Bouzas Maneiro
It is Jessica Bouzas Maneiro who makes it through to round two on her Australian Open debut.
The Spaniard eventually ends the admirable resistance of Sonay Kartal after struggling to close out the match against the stubborn Briton.
A meeting with world number one Aryna Sabalenka could be her reward.

Aryna Sabalenka goes long on the first break point opportunity then wide on the second.
But it's third time lucky for the Belarusian whose deft floating forehand is out of Sloane Stephens' reach, despite her racquet fling attempt.

Jessica Bouzas Maneiro does what she must on serve as we reach the tense, decisive points in the tie-break.
Ah, that's a tough one for Sonay Kartal to swallow. The Briton nets a volley and will face a second match point.
Sabalenka 6-3 1-1 Stephens*
Sloane Stephens has been a pretty composed figure out on court but we're starting to see a bit more animation from the American.
You can see just how hard she's having to graft for these points and she sends one long to give Aryna Sabalenka three break points.
Sabalenka 6-3 1-1 Stephens*
It's not all about power. Aryna Sabalenka comes into the net and applies a bit of touch and delicacy to take the hold to 15.

This has been impressively gritty from Kartal to put herself into this position.
Bouzas Maneiro is not striking the ball as much as she was earlier, true.
But Kartal has still done well to hang tough and give herself a chance of levelling the match.
Kartal 1-6 6-6 (4-3) Bouzas Maneiro*
Into the net by Jessica Bouzas Maneiro and Sonay Kartal has the opportunity to take control of the tie-break on serve.
While the Briton has cut down on her errors, they continue to come from the racquet of Bouzas Maneiro and the Spaniard overhits on the run for 4-2, but Kartal is unable to build on her two-point lead.
Kartal 1-6 6-6 (2-1) Bouzas Maneiro*
This is anybody's set now, something which seemed very unlikely when Jessica Bouzas Maneiro led 6-1 4-1, and again when the Spaniard brought up her first match point.
A loose forehand by Bouzas Maneiro gives Kartal a narrow advantage after three points.
