Over on Margaret Court Arena, another big story may be developing. 32nd seed Milos Raonic has takes the first set 7-5 on 3rd seed Stefanos Tsitsipas.
Much better work from Osaka to stop the run games against her at 4 by breaking Gauff back immediately and then quickly holding for 3-6 2-1*.
A bit of a mental lapse from Gauff in her service game. She double faulted at 40-15 and again on the second deuce before dumping a volley into the net on break point. Now she has to regain her composure.
Current stats on Rod Laver Arena: 4 winners and 10 unforced errors for Gauff. 9 winners and 17 unforced errors for Osaka.
Coco Gauff immediately moves up a set and a break on Naomi Osaka at 6-3 *1-0. A rancid service game from Osaka – she opened with a couple more dreadful backhand errors, then she dumped an easy volley into the net and she dismounted by shanking a forehand well wide. She is playing terribly now and looks extremely flat. Gauff is giving absolutely nothing away.
Coco Gauff takes the first set 6-3 against Naomi Osaka!
Absolutely no fear from the youngster, who sealed out the love hold with a huge unreturned serve out wide. While Gauff is skidding around the court, chasing every ball down and punctuating each winning point with loud cheers, Osaka looks a little too calm. She ended the set with a flurry of backhand errors and that isn’t good enough.
Coco Gauff breaks Naomi Osaka for 5-3 and will serve for the set! The 15 year old is such a fast learner and she is already looking so much more comfortable in the presence of the defending champion. Gauff has soaked up so much of Osaka’s pace in the early exchanges and her defence is clearly in Osaka’s head. Two weak backhand errors in succession from Osaka hand over the first break.
Marin Cilic defeats 9th seed Roberto Bautista Agut 6-7(3) 6-4 6-0 5-7 6-3
A fantastic win for 2014 US Open champion Cilic, who moves into the fourth round after two consecutive five set wins after his fifth set tiebreak win over Benoit Paire. Cilic is unseeded and ranked 39th after struggling with injuries and form in recent months but he has shown this week that he is still motivated and capable of dispatching top opposition.
Cilic will face the winner of Tsitsipas vs Raonic, which is still on serve at 4-3 to the Greek, in the fourth round.
Over on Melbourne Arena, Marin Cilic just roared as he dug out a tough hold from 0-30 down to move to within a game of victory. He leads Roberto Bautista Agut 5-3 in the fifth set.
Good work from Gauff to dig out another solid hold for 2-1* from 15-30 down. She responded well from 15-30: a slick backhand down-the-line winner, an enormous 188kmh unreturned serve and then an easy serve and forehand combination. She is already doing a better job of imposing her game on Osaka.
Gauff and Osaka are underway on Rod Laver Arena and the youngster pieced together an essential opening hold. It was far from easy – Gauff led 40-15 before serving a double fault and then watching an Osaka backhand winner fizz by – but she is moving beautifully as usual and her defence is forcing Osaka into errors.
Serena Williams’s coach, Patrick Mouratoglou, speaks.
Osaka and Gauff are officially on-court. The American won the toss and very confidently decided to serve first.
Over on Margaret Court Arena, Stefanos Tsitsipas and Milos Raonic are also preparing for battle.
Coco Gauff previewing tonight’s match a couple of days ago:
I think I’ll be less nervous this time. I think US Open I was nervous. It was my first time on Ashe. We’re both familiar with each other’s games. She plays really aggressive. This time coming in I’m going to be more aggressive
Lost in the loveliness of Naomi Osaka’s post-match gesture in New York was just how well she handled Coco Gauff during the match. She wanted to make it clear what the pecking order was and she did, rising to the match and playing her best tennis of the tournament. Gauff struggled badly with the weight of Osaka’s ball in New York and her weaker forehand was constantly exposed by Osaka. her attempts to match Osaka’s aggression were futile. It will be very interesting to see what she has learnt since the US Open and how the youngster will approach the defending champ.
On Melbourne Arena, ninth Roberto Bautista Agut just recovered from being a break down to snatch the fourth set 7-5 and push Marin Cilic into a decider. What a brutal second round match this is for everyone involved – a current top 10 player versus a slam champion and former top 10 player.
So, what happened earlier today? A heck of a lot. The big news is that Serena Williams has been upset by Chinese 27th seed Wang Qiang in a dramatic three set battle. Wang played a brilliant match and then showed such impressive resilience to recover after failing to serve out the match in the second set. Williams fought hard but she played a bad match and was punished. A few months ago, Wang and Williams played each other at the US Open and Serena won 6-1 6-0. What a turnaround.
The second big story is that Caroline Wozniacki is no longer a professional tennis player. With her 7-5 3-6 7-5 loss to Tunisia’s Ons Jabeur, that is it. She has officially retired from the sport at 29. There was a lovely ceremony for Wozniacki on-court and she departed Melbourne Arena with an incredible career behind her. 30 titles, 1 slam, $34m prize money, 71 weeks at #1 and twice year-end #1. She was never the most talented player at the top of the sport but she was a true winner and one of the most mentally strong athletes around. Still, a great result for Jabeur who made history as the first Arab woman to reach the Australian Open fourth round.
Meanwhile, Ash Barty, Novak Djokovic and Petra Kvitova all cruised through. Barty defeated Elena Rybakina 6-3 6-2. Djokovic won 6-3 6-2 6-2 with an insane serving performance, losing only one point on serve after two sets. Kvitova eviscerated Ekaterina Alexandrova 6-1 6-2.
Hello! Welcome to our coverage on night 5 of the Australian Open. What a night session we have in store. We begin on Rod Laver Arena with one of the most anticipated matches of the tournament as 3rd seed and defending champion Naomi Osaka faces 15 year-old child star Coco Gauff.
We all know what happened when the two faced off a few months ago at the US Open. After Osaka’s statement 6-3 6-0 victory, she comforted Gauff and convinced her to address the crowd. The night ended with both women embracing each other in tears, the footage going viral across the internet. Despite the lovely sportsmanship in New York, Gauff will be desperate to give a better account of herself and to show what she can do against the very best.
3rd seed Roger Federer will follow them on Rod Laver Arena in a match that will generate just as much excitement in Australia as he faces home favourite John Millman. The pair have played three times, with Federer winning two of their meetings, but one meeting that people will remember is their 2018 US Open fourth round when Millman stunned Federer with a 3-6 7-5 7-6(7) 7-6(3) upset in the suffocating New York humidity. Federer has played great so far but what a joy it would be for the Aussie to score an upset on home soil.
On Margaret Court Arena, 6th seed Stefanos Tsitsipas will face 32nd seed Milos Raonic and then former quarterfinalist Zhang Shuai will take on 14th seed Sofia Kenin. Elsewhere, Marin Cilic is leading 9th seed Roberto Bautista Agut by two sets to one and Tennys Sandgren is up against Sam Querrey. Later on, 12th seed Fabio Fognini will be in action against 22nd seed Guido Pella.
