10:08 - Kyrgios 5-7, 6-4 Humbert

09:28 - Kyrgios 5-7 Humbert

What terrific returning from Ugo Humbert to get the first break of the match at the ideal time.

08:50 - Garcia 2-6 Osaka

First set to Naomi Osaka on Rod Laver Arena. This is just relentless from Osaka, using her power to get to three set points - but Garcia grits her teeth and shores up her serve to level at deuce. Then she double-faults to hand over a fourth set point, which Osaka finally snaffles. A swift first set for the third seed, who isn't really exerting herself too much as yet.

“Very tough match," he said post-match. "It was difficult conditions. We had very warm and long rallies. I want to give a hand to Frances again for a great fight. It was a fantastic match on his part.
"If I was to choose I would like to have these kind of matches in the opening week but the matches are only going to get tougher with higher seeds each round progressing in the tournament. It’s not the first time that I’m in this kind of situation. I know how to handle this kind of circumstances but at the same time I was fortunate to get through the third set today.
"It was really anybody’s game and Frances played great served very well. It’s probably the most aces I’ve served to someone in a long time so it was just high quality tennis. He gave it all and it was an unfortunate warning that took away the first serve from him at 30-30 when I broke his serve. These kind of things are just unlucky because he deserved better. But it is what it is and I hope he’ll have a great year.
“Various things affect my positive performance here at the Rod Laver Arena. Over the years when you win a lot on a certain court you feel more comfortable coming to the same court each year.
“It feels like my living room, I feel comfortably playing here. The surface has changed over the years, it’s the quickest court I have ever played on here at Rod Laver Arena in the last 15 years so you need a big serve.”

04:30 - Cirstea: Very happy after hard quarantine

"I’ve had a lot of matches against Petra and she’s an amazing player," Sorana Cirstea said after beating Petra Kvitova in three sets.
"She hits the ball so hard and it took me a while to adjust to the game but once I was in there I felt that I could beat her and I felt quite confident. I’m really happy and very happy with this win. In the second set she stepped up a bit and I backed off and I think today was a matter of who took control of the point.
"In the second I played too defensive but once that was over I tried to get back closer to the line and to try to dictate the point and it worked.
The main thing right now is recovery. I was one of the few in hard quarantine so right now playing two hours in 30 degrees heat takes a bit more out of me than normal but it’s impressive to come out of quarantine for 15 days without hitting a ball and be able to compete the way I did today. I did not expect it.

It's Day 3 of the Australian Open and we have some cracking games in store. First up it's Bianca Andreescu vs Hsieh Su-wei.
Mats Wilander in the Eurosport Cube is delighted to see Andreescu back. The Canadian had been away from competitive tennis for 15 months before the slam.
"I love the way she plays. Her body language is very positive. She's very creative, can hit a great a variety of shots and is also a great mover."

"Any time we see Andreescu back on the court we are happy."

Today's top action

It's another packed schedule in Melbourne on Wednesday with Grand Slam champions everywhere you look - Serena Williams, Novak Djokovic, Dominic Thiem, Naomi Osaka and Bianca Andreescu to name just five, and that's just in the singles.

Meanwhile, Canada's Andreescu - just returning to full fitness - will have plenty to think about as she starts the day on Rod Laver Arena against Hsieh Su-wei. There could be fireworks.
