Stefanos Tsitsipas, the world No6 from Greece, said on Wednesday that he had experienced “Nirvana” during his quarter-final meeting with Rafael Nadal. Imagine how he must have felt afterwards, having rallied to beat Nadal from two sets down.
Tsitsipas is a romantic soul and this was a thrilling night, which – had it only been blessed with spectators – would have been a contender for match of the tournament. With a crowd, though, the result might have been different. A loner by inclination, Tsitsipas enjoyed the silence so much that he reached the fabled “zone” where the body starts moving without conscious instruction.
“I was very serene during the match,” said Tsitsipas, after joining another select group: that of players with one-handed backhands who have beaten Nadal. “Maybe the absence of the crowd kept me like this.”
“Nothing was going through my head,” he added. “I think at the end of the third set I changed few things. But then it just took off by itself. I just played more flawless. I really didn't care, honestly.”
For Tsitsipas, it felt like an out-of-body experience. For Nadal, by contrast, the weakness of the flesh was increasingly evident.
After a dominant start, Nadal could perhaps have wrapped the win up in three sets, had it not been for a couple of botched smashes – a blue-moon event, given that his overhead is usually steadier than the price of gold.
But once Tsitsipas took control, it felt like Nadal didn’t have the legs to stay with him. Here was another rarity: the game’s most physical and implacable competitor running out of gas. Some observers pointed to his age – he will be 35 in June. But an alternative explanation lies in last month’s atypical build-up.
Perhaps this is what it takes for the legends of the men’s game to be overturned by the next generation: freaky circumstances like empty stadia and global pandemics, knocking them out of their usual watertight routines.
In his post-match interview, Nadal insisted that he had not suffered a recurrence of the back trouble that afflicted him in the build-up. But he did acknowledge a general lack of conditioning.
“Physically I was not fantastic but not bad,” Nadal said, after a 3-6, 2-6, 7-6, 6-4, 7-5 defeat that leaves him still level with Roger Federer on 20 major titles apiece. “Is true that I probably need a little bit more time because for 20 days I was not able to practice the way that I expected, not able to play one single match in ATP Cup.”
Asked about the numerous injuries that have cut short his Australian Open challenges over the years – and limited him to a single title in Melbourne – Nadal was typically philosophical. “We can find excuses or reasons or maybe this quarantine that we need to be more time in the [hotel] room than usual. But I am not the guy that I gonna find excuses on that. Just accept. Doesn't matter the injuries that I had. I think I am very lucky person.”
The result means that Novak Djokovic – who will face Russian qualifier Aslan Karatsev this morning – is the only man left in the tournament with a major to his name. Meanwhile, Tsitsipas has earned what promises to be a feisty semi-final against Russia’s Daniil Medvedev, who had taken care of compatriot Andrey Rublev in a much more straightforward quarter-final earlier in the day.
There has been an edge between these two since their meeting at Miami in 2018. That match degenerated into such a heated argument that the chair umpire had to shoulder in front of Medvedev, preventing him from challenging Tsitsipas as he collected his bag and flounced off the court.
“I might have said in the past that he plays boring,” said Tsitsipas of Medvedev. “But I don't really think that. He just plays extremely smart and outplays you. He's somebody I really need to be careful with.”
In the men’s doubles, meanwhile, there is guaranteed to be at least one Briton in the final after Jamie Murray and Joe Salisbury both won their respective quarter-finals. As a result, Murray and Bruno Soares (of Brazil) are thus due to face Salisbury and Rajeev Ram (of the USA) in a semi-final that will have the secondary bonus of deciding British bragging rights.
“The stakes are high,” said Murray, “but it’s not like I am playing one of my peers, like Colin Fleming or Ross Hutchins, when there would be that awkwardness. Joe is a lot younger than me so I don’t feel [awkward] going into this match.”
See you soon!
We'll leave it there for this live blog but join us again tomorrow for live coverage as world No 1 and top seed Novak Djokovic takes on Russian qualifier Aslan Karatsev.
"I am speechless. No words can describe what happened out on court, my tennis speaks for itself. It is an unbelievable feeling to be able to fight at such a level and leave my all out on the court.
"Today's performance was... I was very nervous, I won't lie, but I don't know what happened after the third set - I fly like a little bird and everything was working for me.
"The emotions at the end are indescribable."

A reminder that there are no fans in the crowd. But that will change tomorrow with 7,477 fans allowed to be on Rod Laver Arena for each session.
Eurosport pundit Tim Henman previews the upcoming match and feels the withdrawal of Matteo Berrettini will be "helpful" to Tsitsipas as he prepares to take on Nadal.
"I think it’s helpful for Stefanos, there’s no doubt about it. When you are going to play Nadal you need to have a full tank, full of energy," he said.
"He would never wish that on his opponent, but now that he is through he has got to take advantage.
"I’m sure he’ll probably have a decent practice session, he was preparing for the match so he’ll want to go out there and hit some balls with his coach but then change his focus from what would have been a difficult match against Berrettini to what will be an even bigger challenge against Nadal."
Can Nadal end a long wait?
Hello and welcome to coverage of the last quarter-final of the men's draw between Rafael Nadal and Stefanos Tsitsipas.
Tsitsipas will be hoping to gain revenge on Nadal and end the Spaniard's bid for a record 21st Grand Slam title when they meet in a rematch of their last-four encounter in Melbourne two years ago.
The Greek made his Grand Slam breakthrough at Melbourne Park in 2019, defeating Roger Federer in the fourth round before his remarkable run was halted in ruthless fashion by Nadal, who conceded just six games.
Tsitsipas has since established himself as a mainstay in the top 10, winning the ATP Finals in 2019, but the 22-year-old will have his task cut out against Nadal, who has won six of their seven meetings.
Nadal, 34, was all doom and gloom about his fitness on the eve of the year's first major but the lower back strain that forced him to miss the ATP Cup seems to be improving and he heads into the last-eight clash without the loss of a set.
"I was able to win four matches already, so now I'm going to have a very tough opponent and need to play my best," Nadal said after his fourth-round demolition of Fabio Fognini.
"I'm excited. If we compare how I was five days ago and now, it's different, my perspective and excitement is different too."
Meanwhile, Karolina Muchova said she was so dizzy she thought she was going to faint during her Australian Open quarter-final against Ash Barty before a lengthy medical timeout helped her regain her composure to turn the tables on the world No 1.
Home favourite and top seed Barty was leading by a set and a break when Muchova called for the timeout at a steamy Rod Laver Arena.
"I was feeling kind of dizzy at some point, like really lost and almost fainting. I just asked for help," said Muchova, who won 1-6, 6-3, 6-2 to reach the semi-finals.
"They just checked my (blood) pressure because I was a bit lost, you know? I was spinning. So they cooled me down a bit with ice, and it helped me."
Play resumed nine minutes later and a recharged Muchova found her feet almost immediately, breaking Barty's serve for the first time in the match.
With shortened rallies and bold shot-making, Muchova went on to break her opponent twice in the final set to reach a Grand Slam semi for the first time.
