Former British number one on BBC Radio 5 Live and BBC SoundsLorenzo Sonego is just pulling the trigger on so many shots isn't he, he's just going for broke, I guess he feels like he's just got to roll the dice out here and take those risks and see if it will pay off [against Ben Shelton].

*Shelton 6-4 7-5 4-6 5-6 Sonego
Lorenzo Sonego, 29, is on his best run at a major. Indeed this is the first year he has been beyond the third round at Melbourne.
He's currently ranked 55 in the world, although that's going to shoot up on Monday.
He was part of the Italy team that won the 2023 Davis Cup.

*Shelton 6-4 7-5 4-6 5-6 Sonego
Ben Shelton, 22, has slowly been rising up the rankings - having reached the quarter-finals at Melbourne Park in 2023 and the US Open semi-finals last year.
He comes from a properly tennis family. His Dad Bryan Shleton won two ATP titles, while his mum Lisa Witsken Shelton boasts a fine junior record.
His uncle, Todd Witsken, reached the Australian Open quarter-finals in 1988.
Tennis is in his genes.

Shelton 6-4 7-5 4-6 5-5 Sonego*
There's action on Rod Laver Arena right now with American Ben Shelton and Italian Lorenzo Sonego deep into the fourth set.
Three hours and 33 minutes and counting.
Some interesting stories behind this particular match up, which I shall tell you about shortly.
Keys keeps up winning streakpublished at 08:14 Greenwich Mean Time
Keys 3-6 6-3 6-4 Svitolina
Image source, Getty ImagesElsewhere today, Madison Keys reached her sixth Grand Slam singles semi-final.
Earlier, Keys continued her own fine form with a 3-6 6-3 6-4 win over Svitolina.
Keys is on a 10-match winning streak and won the Adelaide Open title a fortnight ago.
The 29-year-old is hoping to reach her second Grand Slam final, having lost to close friend Sloane Stephens at the 2017 US Open.
She was broken late by Svitolina in a tight first set and came through a tricky first service game in the second before growing into the match.
Keys claimed crucial breaks midway through both sets to see off the Ukrainian and reach a third Australian Open semi-final.
Swiatek leads the head-to-head between the pair 4-1 - but Keys did win their last hard-court meeting in Cincinnati in 2022.
"Madison is a great player and really experienced, so you never know," Swiatek said.
"The match that I lost, she kind of killed me, so I think it can be tricky."

The two dislikes on the 08:03 post are semi-finalists Madison Keys and Paula Badosa. Probably.
'Sabalenka hasn't been quite on it'published at 08:09 Greenwich Mean Time
Sabalenka 6-2 2-6 6-3 Pavlyuchenkova
Annabel Croft
Former British number one on BBC Radio 5 Live and BBC SoundsI feel like with Aryna Sabalenka she just hasn't been quite on it, I know she's defending and she's won it the last two years.
I certainly picked her to win it this year but at the moment if you went just purely on the tennis I would go with Iga Swiatek.

Sabalenka 6-2 2-6 6-3 Pavlyuchenkova
Both Swiatek and Sabalenka are in semi-final action tomorrow.
I know I just hinted at top seed Sabalenka being at the top of her game, but I might want to rephrase that. Yesterday Anastasia Pavlyuchenkova gave her a real scare, taking their quarter-final to a decider.
Postpublished at 08:03 Greenwich Mean Time
We're not supposed to have favourites, but does anybody else really want to see an Iga Swiatek - Aryna Sabalenka final with both players at the very top of their game?
It would be proper 'unstoppable force against an immovable object' stuff.
Swiatek's superiority - the statspublished at 08:01 Greenwich Mean Time
Navarro 1-6 2-6 Swiatek
Swiatek's dominance on clay is no secret, with the Pole having won four of the past five French Open titles.
But she has struggled on the fast Melbourne hard courts, having only gone past the fourth round once before this year.
Under new coach Wim Fissette, Swiatek has been ruthless.
Only three players in the Open era have dropped fewer games than Swiatek's 14 on their way to the Melbourne last four.
She has not dropped a single game on serve in her past four matches, and none of her matches so far have lasted more than 90 minutes.

Navarro 1-6 2-6 Swiatek
Annabel Croft
Former British number one on BBC Radio 5 Live and BBC SoundsI was watching Iga Swiatek against Emma Navarro, a quality class opponent and she kind of demolished her. Even though she said in her interview that it was a lot tougher than the score line showed, which it sort of was, but she never ever looked in doubt of winning it.
There is a definitely a different look about her this year, mentally, everything aout her, she looks revived, hungry and motivated.

Navarro 1-6 2-6 Swiatek
Image source, Getty ImagesA few hours ago Iga Swiatek dropped just three games as she breezed past Emma Navarro to reach the Australian Open semi-finals and continue her bid for a maiden Melbourne title.
Five-time major winner Swiatek was ruthless in a 6-1 6-2 victory over eighth seed Navarro.
Swiatek has dropped just 14 games at Melbourne Park this year - and seven of those came in her first-round match.
The Pole will face Madison Keys in the last four after the American came from a set down to beat Elina Svitolina.

Not sure how we got onto star sign chat so quickly. Jannik Sinner's a Leo and apparently they and Aquariuses (Aquari?) don't get on.
Anyway, we'll go through their stats in a little bit, but first there are some tennis results I've got to tell you about.

Like all the best people, Alex de Minaur has a February birthday. Makes him an Aquarius.
Unique, creative and unpredictable apparently. Sounds about right.

Sinner v De Minaur
Jannik Sinner vs Alex de Minaur.
The world number one, against the home favourite.
An Australian man has not won the singles title at Melbourne Park since Mark Edmondson in 1976. The Aussies are pinning their hopes on 25-year-old De Minaur.

Right now American Ben Shelton is 6-4 7-6 4-6 1-1 up against Italy's Lorenzo Sonego.
We'll be chucking in the odd update from that match.
Once it's finished though, it'll be time for Wednesday's showpiece. The reigning champ against Australia's finest.

Image source, Getty ImagesIt's a cooler one in Melbourne today, a bit of a gentle breeze too.
The sun may not be as harsh as it usually is, but it's still much better in Australia than it is in Salford.
Cold drizzle here. Rubbish.
Thankfully, top class tennis always cheers me up, and we're expecting a cracker later this morning.
