This year's Australian Open is really starting to heat up as we enter the tournament's second week. Jannik Sinner is in action against fellow Italian player Luciano Darderi, with the winner earning a place in the quarter-finals. His biggest title rival Carlos Alcaraz is already safely through, having beaten Tommy Paul to set up a last-eight meeting with Alex de Minaur.
Novak Djokovic has also booked his place in the quarter-finals without even stepping onto the court. He was due to face Jakub Mensik but the Czech player was forced to withdraw from their match because of an injury. On the women's side, reigning champion Madison Keys has been dumped out by Jessica Pegula, while Iga Swiatek must beat qualifier Maddy Inglis to earn herself a place in the final eight.

KEY EVENTS
Schedule changed due to extreme heat
The schedule for the Australian Open has been altered for the second time in four days because of extreme heat.
Temperatures are expected to reach 42 degrees on Tuesday as the blistering heatwave continues.
The start of the wheelchair events have been postponed until Wednesday, while play on the outside courts has been moved forward to 9am local time (10pm UK time).
The singles quarter-finals will take place on Rod Laver Arena and Margaret Court Arena, which have retractable roofs and air conditioning systems.
Jannik Sinner breaks silence on banned devices
Jannik Sinner has admitted now knowing that WHOOP devices were banned at Grand Slam tournaments.
He wore one before facing Luciano Darderi earlier today but was ordered to remove it by the umpire during the coin toss.
Afterwards, Sinner said: "Rules are rules, I understand and I won't use it again.
"The umpire asked me straight away if this was a tracker. I said: 'Yes.' He said: 'Remove'. It's fine.
"There are other things we could use. You know it's the vest but it's a bit uncomfortable for me. You feel like you have something on your shoulders and it's a bit different."
Ben Shelton defeats Casper Ruud
Ben Shelton has booked his place in the Australian Open quarter-finals with a four-set victory over Casper Ruud.
The young American lost the first set but mounted a brilliant recovery to secure a 3-6 6-4 6-3 6-4 triumph.
It marks the third time Shelton has reached the last eight at Melbourne Park.
Lorenzo Musetti seeks Novak Djokovic revenge
Lorenzo Musetti has vowed to push Novak Djokovic to his limits when they meet in the quarter-finals of the Australian Open.
"I think it will be a tough match, for sure," he said. "Of course, he's feeling good. He hasn't lost a set.
"He had the chance to rest for a few days. I think at this age, I think he was happy about it, of course, to try to be well-prepared and well-relaxed for this match.
"But of course, we know each other pretty well because we played a lot. Just won once against him.
"Hopefully, I'll take my revenge, because last time in Athens we were really, really close. I feel like I have another chance now.
"I think the thought that I have and the mentality that I have to put on the court in the next match against Nole is probably that one, trying to go for winning the match and not playing the match.
"I feel ready to try to push him to his maximum."
Learner Tien hailed over 'tactical mastery'
Nicolas Escude believes Learner Tien produced a tactical masterclass during his straight-sets victory over Daniil Medvedev.
"I’ve never seen Tien overplay or overheat," stated the Frenchman.
"On the other hand, he was absolutely perfect in his tactical mastery of the match and in the way he approached it and played Medvedev.
"That was extraordinary. Medvedev likes a fight, a fast pace, shots played diagonally. For two sets, Tien didn’t give him the same ball twice.
"He never stopped moving him around with his left foot. Daniil ended up completely missing the mark, of course.
"But what we should remember is Tien’s tactical mastery, which was quite extraordinary."
Wins for Jannik Sinner and Iga Swiatek
Jannik Sinner has just beaten Luciano Darderi in straight sets to reach the quarter-finals of the Australian Open.
It was quickly followed up by Iga Swiatek wrapping up a similarly one-sided victory over Maddy Inglis.
Sinner was taken to a tiebreak in the final set but prevailed to earn a 6-1 6-3 7-6 triumph.
Swiatek, meanwhile, won every game in the opening set of her 6-0 6-3 win over Inglis.
Jannik Sinner ordered to remove banned device
Jannik Sinner is the latest player to fall foul of the rules regarding WHOOP devices at the Australian Open.
He was forced to remove the fitness tracker before facing Luciano Darderi after it was spotted by umpire Greg Allensworth.
Sinner was wearing the technology under his wristband, but Allensworth spotted it as the players came to the net for the pre-match coin toss.
The young Italian removed it without complaint before the start of the first set.
Taylor Fritz opens up on injury struggles
Taylor Fritz has suggested that injuries played a part in his fourth-round defeat at the hands of Lorenzo Musetti.
He said: "Today I was feeling it from the get-go. I felt good in my warm-up.
"Then when I went to do my pre-match stuff, like moving around and stuff before the match, I just told my physio my knee doesn’t feel great.
"I was hoping it would loosen up. It didn’t get worse but it kind of just stayed the same the entire match.
"My oblique [was also injured]. We tried taping it because I felt like in the first round it wasn’t that big of an issue. In the second round maybe a little bit more..
"Before the tournament I did an ultrasound. After the second round I did an ultrasound. Yesterday I did an MRI on it.
"It’s the exact same thing I had last year that took me out for the beginning of the clay court season and a bit during the hard court season I tried to play through.
"All the scans show that there’s not like an obvious tear there like there was before. But I’m being cautious."
Jannik Sinner mind games begin
Carlos Alcaraz has kicked off the mind games with Jannik Sinner by suggesting that he has an important advantage over the Italian.
High temperatures have caused chaos at the Australian Open this year with the country in the midst of a blistering heatwave.
Quizzed on the tricky conditions, Alcaraz said: "Someone like Jannik has his team, he has everything meticulously planned, and I’m sure they do things right to arrive in top form.
"He’s from a very cold, mountainous region, and I’m from Murcia, where it’s very hot, so the warmer conditions benefit me, I won’t deny it.
"Even so, he’s been on the circuit for a long time, he’s spent many summers here, and I think he’s adapted.
"Although it’s true that sometimes he still struggles a bit, and that could be something we can take advantage of."
Carlos Alcaraz breaks unusual rule
Carlos Alcaraz fell foul of an unusual rule during his victory over Tommy Paul.
He was told to remove his WHOOP device, a wearable fitness tracker.
It caused confusion because WHOOP 3.0, 4.0, 5.0 and MG devices are approved player analysis technology devices under ITF rules.
However, it was confirmed by Tennis Australia that such wearable tracking devices are still not permitted at Grand Slam tournaments.
They said: "Wearables are currently not permitted at Grand Slams. The Australian Open is involved in ongoing discussions on how this situation could change."
Aryna Sabalenka found herself in exactly the same situation earlier in the tournament.
