07:58 - Wilander on AO 50% capacity

Eurosport tennis expert and seven-time Grand Slam champion Mats Wilander commented on the news that the Australian Open organisers will allow fans in for the remainder of the tournament at 50% capacity, starting tomorrow.
"I don’t think it matters if it’s 50% or 100% capacity to be honest," he said.
"I think it is massively different for the players. I think it will favour the big-time players, I think it is huge for the players, they will be so fired-up so it will help the tournament big time in terms of level. I think you’ll most likely see the pressure of the crowd will favour the Nadal’s of the tournament. In general, it will favour the veterans a little more I think. It’s huge. Massive.
"It's the dream come true for sports or events in general to actually see that - 'look they did it, they actually did it in Australia' and actually hopefully the governments of this world will realise that it is tough but that is the way to go about it. It is tough at the beginning but then we can open up. That’s the big message for me."

07:10 - Barty heartbroken to go out

Ash Barty confessed to being heartbroken at coming up short in the Australian Open quarter-finals on Wednesday but did not want the shock defeat to distract from her successful return to tennis after a year on the sidelines.
The world number one returned to the tour for the Melbourne Park warm-up tournaments after staying at home to try to sit out the Covid-19 pandemic, running up an eight-match winning streak before Wednesday's 1-6 6-3 6-2 loss to Karolina Muchova.
"It's heartbreaking, of course," said Barty, who was hoping to become the first homegrown Australian Open champion since Chris O'Neil in 1978.
"But will it deter me? Will it ruin the fact we've had a really successful start to our season? Absolutely not. The sun will come up tomorrow.
"We go about our work again. You're either winning or your learning. We won't let ... this particular hour of tennis deter us from what we're trying to do."

'It's heartbreaking' - Barty reflects on crushing loss to Muchova

In her news conference, Barty channelled her time as a cricketer to repeatedly bat back suggestions that Muchova had gamed the system by taking a medical timeout after losing the opening set.
She instead focused on her inability to take back the momentum once the revitalised Czech started playing her best tennis in the second and third sets.
"I felt like I lost control of the ball a little bit," Barty said.
"I felt like I lost my way with overplaying, overpressing, not letting myself work into the points and really construct points as well as I'd like to."

06:50 - Medvedev: I was cramping up

“The last game of the match I started cramping in my quad," he said post-match. "I knew he was cramping too I saw it. I had to not show it. I managed to make some big serves and then in the end I locked completely.
“I would say the last three points when I was getting ready for the serve I could not really move my left leg so it was not easy and I knew if I lost the game he was going to see it so I was happy I won the game.
“If you come to Australia and it’s plus 40 every day it’s not easy but at least you’re kind of used to it. Here we’ve usually had days where it’s been 20 degrees, 20 maximum and then on the side it’s not that hard.
“Then you come into the quarters against Andrey and we’ve had some unbelievable rallies and after the point it’s tough to breathe. I think I’m one of the first players to make Andrey that tired on the court so I’m quite happy about it.
“We’re all competitive so you can see during the match that nothing matters. You just need to win and get to the semis of a grand slam. I think my game matches his quite well. I’ve knwn him a long time so I know how to neutralise his big shots. It was definitely one of the best matches I’ve played not only here in the last couple of years.
“I’m really happy I can watch a match like this. I don’t think they’ve played many matches on the ATP Tour, but all the matches they’ve played have been three and a half hour matches out of three sets so really interesting to see.
“I’m going to prepare for the opponent, it is not going to be easy whoever wins.”

00:37- Barty takes the first set

Blink and you could well have missed it.

The Czech player has not got going.

00:25 - Barty *3-0 Muchova

The first three games go Barty's way in only nine minutes. Muchova just seems to lack the weapons to cause the world number one any real problems at the moment.

00:20 - Barty 2-0* Muchova

A Muchova unforced error gives Barty two break points already. The Czech players produces a forehand winner at the net to pull one back, but Barty plays a clean forehand into the empty space on Muchova's right having baited her in with a slice.
It's a perfect start for Barty.

00:15 - Barty gets us going

Top Matches

Barty is the home favourite and she will kick things off on Rod Laver Arena when she takes on the 25th seed Karolina Muchova.
The number one seed has been struggling with a thigh problem, but she was impressive in taking care of Shelby Rogers in the previous round.

We forget how good Barty's forehand is - Wilander

The 24-year-old, who won her only major to date at the French Open in 2019, is looking to at least replicate her run to the semi-finals of her home major 12 months ago.
The evening session is all about Nadal and whether he can win his first Australian Open title since 2009.
The Spaniard has not been tested so far in Melbourne, but that will almost certainly change in his quarter-final against Stefanos Tsitsipas.
The Greek is a rising star in the game and having notched a win over Nadal on clay, he will certainly fancy his chances on a hard court.

Potential Upset

The day session concludes on Laver with an all-Russia affair between the fourth seed Daniil Medvedev and the seventh seed Andrey Rublev.
Medvedev has a perfect 3-0 record against his fellow countryman, but there’s not much between the two.
In their most recent meeting, Medvedev triumphed in a third-set tiebreak and with Rublev yet to lose a set in the tournament, the underdog will have high hopes of advancing to his first grand slam semi-final.
