Serbia's Novak Djokovic reacts on a point against Taylor Fritz of the US during their men's singles match on day five of the Australian Open tennis tournament in Melbourne
Djokovic's win over Raonic in four sets brings today's action to a close at the Australian Open. Super Sunday is over! We saw comeback wins from both Naomi Osaka and Simona Halep, with Serena Williams also coming through a tough match to make the quarter finals.
Sascha Zverev is into the final eight in the men's singles while Dominic Thiem crashed out in straight sets to Grigo Dimitrov. Shall we do it all again tomorrow?
The eight-times Australian Open champion and world number one is into the quarter finals for a 12th time! There were doubts over Djokovic's fitness, but there were no real signs of it hindering him here. This had the potential to be a real test. Raonic is swept aside!
12:45 - Djokovic back in control
*DJOKOVIC 6-1 RAONIC (7-6, 4-6)
That turned into a one-sided set in the end with Djokovic winning five games in a row. Raonic needs to gather himself for this fourth set otherwise it will be all over. Djokovic looks to be focused again.
12:15 - Raonic levels it
DJOKOVIC 4-6 RAONIC (7-6)
Raonic takes a set off Djokovic for the first time at a Grand Slam! The world number one has yet to break the Canadian. This is turning into a compelling contest. Djokovic's level dropped for a couple games in the middle of the set and Raonic took advantage.
11:25 - Djokovic takes first set tie break
DJOKOVIC 7-6 (4) RAONIC
Djokovic takes the first set in 56 minutes. Raonic made a bad unforced error with an overhead smash in the first point of the tie break and he never really recovered from that as Djokovic took the second of three set points.
10:10 - Zverev is through
LAJOVIC 4-6, 6-7, 3-6 ZVEREV
Zverev secures his place in the Australian Open quarter finals with an ace. With the exception of the end of the second set when he made things more difficult for himself, this was an impressive performance by the US Open finalist.
10:05 - Comeback win for Halep
SWIATEK 6-3, 1-6, 4-6 HALEP
Halep comes from a set down to secure a place in the Australian Open quarter finals! Swiatek looked to be in control of the match at the end of the first set, but there was a dramatic shift in the dynamic and Halep made the most of some slack concentration from her opponent.
09:30 - Zverev two sets up
LAJOVIC 6-7 (5) ZVEREV (4-6)
Zverev made more of a fuss of that than looked likely towards the end of the second set when he had the chance to serve it out. The German was broken, forced into a tie break where he finally grinds it out against Lajovic, who to his credit hasn't gone away.
09:20 - Halep levels it
SWIATEK 1-6 HALEP (6-3)
We're heading to a deciding set. Halep lifted her game, but the main difference was the dip from Swiatek. That was a peculiar set from the Pole. Too many errors. Too many wrong decisions. Weird.
08:55 - Swiatek takes the first set
SWIATEK 6-3 HALEP
First goes to Swiatek! Very competitive for the most part. Halep just allowed her concentration to slip in the final three games. The Polish youngster has one foot in the quarter finals.
This point below was one of the highlights of that set...
'What a point!' - Swiatek wins incredible rally against Halep
08:35 - Zverev up and running
LAJOVIC 4-6 ZVEREV
Zverev takes the first set in 49 minutes and after a shaky start the number six seed has been in control of this match. The scoreline doesn't actually reflect the extent to which Zverev dictated most points.

18-Elise Mertens (Belgium) v 25-Karolina Muchova (Czech Republic)
The US Open champion, who came back from two sets down to beat Nick Kyrgios in an exhausting third round battle on Friday night, looked out of sorts from the beginning of the contest and made an uncharacteristic 41 unforced errors.
While Thiem's five-set match against Kyrgios had been played in a bear pit at John Cain Arena, Sunday's match was witnessed by only a handful of officials and coaches on Rod Laver Arena as Melbourne's coronavirus lockdown kept the fans away.
Highlights: Dimitrov downs exhausted Thiem in huge shock
07:35 - Zverev in action
Alex Zverev is about to kick off against Dusan Lajovic on Margaret Court Arena.
This will be a rematch of the third-round encounter in the French Open 2019 when Zverev needed five sets to beat the Serb 6-4 6-2 4-6 1-6 6-2.
Kyrgios mocks Djokovic with celebration before doubles match
07:15 - Dimitrov: Thiem might have been struggling
“Throughout every season you have one of those matches where you just keep the ball rolling and I think today was just one of those days," Dimitrov said after his surprise straight sets win over Thiem.
"I was entirely trying to focus on what I was doing and the gameplan I had.
“He might have actually struggled with something which I don’t know, but I want to give myself credit for staying focused and composed throughout the three sets.
“He’s an unbelievable player and a great friend off the court so I’m not going to be that humble. Of course I’m very happy to be in the quarter-finals.”
07:06 - Thiem is OUT!
There we have it. Number three seed Dominic Thiem has been knocked out of the Australian Open in a straight-sets defeat - 6-4, 6-4, 6-0 - to Grigor Dimitrov on Rod Laver Arena.
Last year’s finalist looked tired following his five-set comeback victory over Nick Kyrgios on Friday and lacked any spark straight from the off against the Bulgarian number 18 seed.
Dimitrov, who entered the match notably fresher after Pablo Carreno Busta was forced to pull out early of their third round clash through injury, has not dropped a set at this year's Australian Open so far.
Dimitrov will face Russian qualifier Aslan Karatsev in the quarter-finals.
07:02 - Dimitrov 5-0 up in third set
Dimitrov is just one game away from the quarter-finals as Dimitrov breaks again.
Thiem is not looking sharp at all and it will be interesting to hear his post-match comments.
06:55 - Thiem double broken
Dimitrov motors on. He wins four points in a row and he is racing to the quarter-finals with a 3-0 lead in the third set. Can Thiem muster up something this late on?
06:53 - Thiem in trouble
Dimitrov is a break up in the third after Thiem comes to the net and slices out.
The number three seed looks to be completely out of ideas. He's struggling to work out Dimitrov's game and nothing seems to be working for Thiem at the moment.
Has that comeback against Kyrgios completely knackered him? It's looking that way at the moment.
06:45 - Dimitrov breaks
Thiem's drop shot hits the net and Dimitrov is 5-4 up and will serve for a two-set lead. Thiem in big trouble right now.
06:30 - Back-to-back breaks
Thiem, who is showing signs of fatigue in some of his play, broke Dimitrov's serve before the Bulgarian pulled it straight back. Dimitrov leads 6-4, 2-3 on Rod Laver Arena.
Highlights: Qualifier Karatsev shocks Auger-Aliassime as run continues
06:02 - Dimitrov takes first set
After 57 minutes, Dimitrov produces a quality opening set 6-4 to take the lead against Thiem.
05:51 - Dimitrov breaks!
The commentators curse strikes! Dimitrov has broken Thiem not once but TWICE to take a 4-3 lead in the opening set. How things can change...
05:40 - Thiem surging through opening set
The Austrian dropped his opening two sets against Nick Kyrgios in the previous round, but he doesn't look like he will have such problems this time. He leads Dimitrov 3-1 in the opening set.
05:20 - Hsieh: I don't care if I lose Osaka match
Hsieh Su-wei said she cares not whether she wins or loses her first Grand Slam quarter-final against Naomi Osaka later this week after continuing her stunning run at the Australian Open on Sunday.
Hsieh said she would probably get "smashed" by the three-times Grand Slam champion but was looking forward to testing her problem-solving skills.
"I'm quite enjoy to playing every match, even if I get tortured," the three-times Grand Slam doubles champion said.
"I don't really care I win or I lose. I just try my best and play the game. All the girls, they play different games. It's very interesting when you have some difficult situations.
I want to try to find a way and try to get into the game. At least I try. If I lose, I don't lose anything. It's no problem for me.
Highlights: Hsieh beats Vondrousova to reach first ever Grand Slam quarters
05:10 - Karatsev wins five-set epic
Wow. Felix Auger-Aliassime is out of the Australian Open after losing to 3-6, 1-6, 6-3 6-3 6-4 unseeded Russian qualifier Aslan Karatsev who is playing in his first ever grand slam.
Auger-Aliassime looked to have it in the bag after the opening two sets, but Karatsev's fairytale run continues as he follows up his straight sets win over Diego Schwartzman with another major shock.
He will face Dominic Thiem or Grigor Dimitrov in the next round.
05:05 - Thiem vs Dimitrov underway
The highly-anticipated match between the third seed Dominic Thiem and Nick Kyrgios lived up to the billing as the pair played out an entertaining five-setter on Friday.
Thiem now has a new challenge on his hands in the shape of Grigor Dimitrov. He won the opening seven games of his third-round match before Pablo Carreno Busta was forced to retire, trailing 0-6 0-1.
The Bulgarian, who is yet to drop a set, should be fresh coming into this one. The 18th seed actually leads 3-2 head-to-head against Thiem so this should be a cracker.
04:59 - Serena: I had to keep going
“I am happy to get through," she said post-match. "It wasn’t easy and I knew it wasn’t going to be easy. She was teeing up on every shot and I felt like I was there but there were some I was missing. Even the games that I lost were super close. I just thought ‘Serena, you got this’ so I just had to keep going.
“I lost the second but the games were so close and could have gone either way. I was just like ‘come on Serena you can do this’ and stay in there.
Serena: 'Having Venus around is amazing' in Melbourne
On her sister Venus Williams: “It helps a great deal having Venus around is amazing. Not just now in the twilight of our careers but also the beginning. It’s so cool because no one understands the level of intensity or the pressure of the losses and the wins unless it’s someone else in the locker room. She gets it.”
On her fashion line: “On my day off, on my email I have ‘out of office’ but as CEO I had to step up and I was on the phone with my designer making final orders and deciding how much fabrics we need for our new collections etc. and I was thinking ‘oh my gosh I have to play tomorrow but we have to get this done’. We have some exciting stuff.
On getting gifts for Valentine’s Day: “You’ve definitely put him [Serena’s husband] in an awkward position. I actually don’t celebrate Valentine’s Day or holidays for that matter. He’s pretty lucky because he doesn’t have to get me anything but he always surprises me when I least expect it. Every day is like a special day for us.”
04:42 - Serena wins it!
Serena Williams is into the Australian Open quarter-finals for the 13th time in her career with a 6-4, 2-6, 6-4 win over Aryna Sabalenka on Rod Laver Arena.
The 23-time Grand Slam winner, chasing Margaret Court’s slam record of 24 singles slams, was made to work hard by the Belarusian in a match full of powerful forehand hitting from the baseline.

04:19 - Sabalenka 4-6 6-2 *1-3 Serena

04:13 - Sabalenka 4-6 6-2 *1-1 Serena
Sabalanka is playing some ferocious tennis. She double faulted to hand Serena a break point, but she responded with an ace that almost left Serena on the floor, a crushing forehand winner and an unreturned serve.
04:02 - Sabalenka 4-6 *6-2 Serena
Sabalenka wins the set on her serve, taking it in 46 minutes to set up a third-set decider.
Serena's serving is really letting her down. She only had a 36% first serve percentage in that. It's something for the 39-year-old to really think about in this final set.
Karatsev is one game away from taking the fourth set against Auger-Aliassime where it's 6-3, 6-1, 3-6, 3-5.

After three break points, Sabalenka finally grinds down Serena to get back to being two breaks in front in the second set full of hard hitting.

03:35 - Sabalenka 4-6 3-0* Serena
With her second break point, Sabalenka has broken Serena once again as the 39-year-old hits a forehand long. This set looks like it belongs to the Belarusian number seven seed.

Serena leads 6-4 after 43 minutes.
Karatsev is a break up in the third set against Auger-Aliassime as he looks to mount a comeback. It's currently 6-3, 6-2, 2-4 in that one.
03:00 - Sabalenka 3-4* Serena
Serena saves two break points against the Belarusian. If you want to see two players absolutely battering a tennis ball then this is the match for you!

Auger-Aliassime is a set away from his first ever Grand Slam quarter-final. He leads Karatsev 6-3, 6-1 and is playing very well.
02:45 - Sabalenka 2-2* Serena
As expected we have seen plenty of big hitting from both players so far but we are still on serve in the opening stages of this first set. Serena's serving has been ruthless so far.

“I feel like today I didn’t really know what to expect because I’d never played her before," she said post-match. "But I knew it was going to be tough. I’m kind of tired right now.
“Today I feel like I was a bit intimidated because I knew she was playing really well coming into this match and for me I feel like in the stressful points I feel I have to go within myself and I know that today I probably hit a lot of unforced errors. I think that was something I needed to do because I couldn’t really give her any short balls because she’d finish it.
“I’m not really looking forward to it. She’s going to be really tough. Every time I’ve played her its three sets. Really long so I think I played her two years ago here so it’s actually fun when I’m not really angry.
“It [Hsieh’s style] makes it really tricky. I know the people she’s played are super difficult and you know for me whenever I play her I have to expect everything.”

Highlights: Osaka back from the brink to reach quarter-finals

01:59 - Muguruza 6-4, 4-6, *5-5 Osaka

Osaka saves two match points and produces two aces to hold her serve. Muguruza will serve for the match.
01:50 - Muguruza 6-4, 4-6, *5-3 Osaka
Muguruza is finding more joy towards the front of the court as she looks to seal this tie with attacking tennis.
Again she comes up with the goods on an immense game point, firing a ferocious backhand down the line to go within one game of the quarter-finals.
Annabel Croft in commentary says that was the shot of the match and she's right.
01:45 - Muguruza 6-4, 4-6, *4-2 Osaka
Muguruza wins a point at the net before an Osaka unforced error hands the Spaniard the service game. Muguruza lets out a roar.
01:37 - Muguruza 6-4, 4-6, 3-2* Osaka

01:29 - Muguruza 6-4, 4-6, 1-2* Osaka

01:17 - Muguruza 6-4, *4-6 Osaka
Osaka squanders her first two break points before getting another and clinches it.
Like Muguruza in the first set, Osaka comes from a break down to send this to a decider.
Hsieh, 35, is into the quarter-finals of a Grand Slam for the first time in her career with a 6-4, 6-2 win over Vondrousova on Margaret Court Arena.
Vondrousova looked a bit unwell and out of sorts in that. She will be disappointed to lose in straight sets having beaten Sorana Cîrstea, Rebecca Marino and Rebecca Peterson to get to the fourth round.
01:08 - Muguruza 6-4, 3-4* Osaka
It's getting tense. Osaka is holding her own but still making a lot of unforced errors. We are creeping towards the conclusion of this second set.
00:56 - Muguruza 6-4, *2-2 Osaka

Despite some blistering forehands and hitting more winners, Osaka simply made too unforced errors in that - 13 compared to Muguruza's 6 - and it has cost her.
It's been relatively straightforward for Hsieh against Vondrousova. She takes the first set 6-4 as the 35-year-old aims to reach the Australian Open quarter-finals for the first time in her career.
00:40 - Muguruza 5-4* Osaka
Muguruza breaks Osaka at 4-4 with her second break point. Momentum is with the Spaniard and quite possibly this first set.
00:29 - Muguruza 2-3* Osaka

00:22 - Muguruza 1-2* Osaka
Muguruza breaks straight back after Osaka swings a wild forehand into the net. We're back on serve!
00:20 - Muguruza *0-2 Osaka

And Osaka kicks us off with a thumping ace.
Su-Wei Hsieh, who knocked out Bianca Andreescu last week, is playing the 19th seed Marketa Vondrousova on Margaret Court Arena and has already raced into a 2-0 lead.
Mats Wilander gives Barbara Schett in the Eurosport Cube his thoughts on Garbine Muguruza and Naomi Osaka ahead of their mammoth clash.
On Muguruza: “She’s playing incredibly good tennis. I’d like to see her play one close match before she faces players like Naomi Osaka but I look Muguruza on this service. I’m surprised she’s won her two majors in paris on clay and Wimbledon on grass. Before she won on hard courts.
“She doesn’t mind coming forward, she hits the ball hard enough, heavy enough and takes it early so the courts will suit her. I think her best tennis may still be a couple years in the future and win a couple more majors.”
On Osaka: “She’s looking so confident and the more I see her play she reminds me of Serena Williams. She gives that vibe off that she’s full of confidence.
"I don’t know what style you have to play to beat her but I do think Muguruza has the chance to take a little bit of time away from Osaka.”
Interestingly these two have never met on the tour before. This will be intriguing.
Osaka is on a 17-match winning steak, with the help of two midweek withdrawals, and will be the favourite. Muguruza, meanwhile, is also playing well. She reached the Yarra Valley Classic final and has a 9-2 win-loss record.
00:00 - Here we go!
