Novak Djokovic dramatically retired from his Australian Open semi-final against Alexander Zverev after being unable to play through a torn muscle in his upper left leg before admitting there is a “chance” may have played at the tournament for the final time.
The 37-year-old conceded the match immediately after putting a simple volley into the net on set point, and was strangely booed by some sections of the crowd when walking off the court despite clearly struggling with the injury during the 82-minute opener.
Djokovic sustained the injury during his dramatic comeback win over Carlos Alcaraz in Tuesday’s quarter-finals, where he played through pain, and admitted he did not have anything left in the tank after being unable to train on Wednesday or Thursday.
While the injury ended his bid for a record 25th grand slam title in Melbourne and cast doubt over his future, Djokovic insisted that he is determined to come back and compete for more trophies. “I’ll keep going. I’ll keep striving to win more slams,” he said. “And as long as I feel that I want to put up with all of this, I’ll be around.”
His retirement means Zverev advances to his first Australian Open final, where the German second seed will face Jannik Sinner after the defending champion and World No 1 saw off Ben Shelton in straight-sets.

Novak Djokovic was booed off the court by some sections of the Rod Laver Arena crowd after retiring from semi-final against Alexander Zverev.
Djokovic stopped after raising his thumbs as he left the court at the end of the first set, to audible jeers from some fans.
The 37-year-old was asked about that reaction in the Serbian section of his post-match press conference.
"I don't know what to say,” Djokovic said. “People have come and paid for the tickets expecting a great match and a big fight, which they didn't get.
"From that perspective, I can understand. I am doing my best to understand them, but I am not sure whether they understand me or if they even want to."
“I know how my body works, what I feel, and I know how much I’ve given to this tournament in the past 20-plus years. I will stop here, so that I don’t continue (speaking) in the wrong direction.”

“I actually thought I played really well, as well as I played the last 12 months, to be honest,” Djokovic said.
“Of course, it was never going to be an easy battle, an easy match for me. Neither it was for Sascha, even if I was not injured.
“But as I said, I think I was striking the ball very well. A lot of positives to take in terms of how I reached the semi-finals. It’s a very good result considering the circumstances.
“But it’s not satisfying to me, for my standards. I always look for the highest goal, to reach the finals and fight for a trophy.”

Novak Djokovic said after his quarter-final victory over Carlos Alcaraz that he would have retired from the match if he had lost the second set.
He went on to say he would have tried to continue against Zverev if had had won the first set, but admits the idea of playing four or even five sets was too much.
“I didn’t hit a ball since Alcaraz match, so until like an hour before today’s match. I did everything I possibly can to basically manage the muscle tear that I had, medications and the strap, and the physio work helped to some extent today.
“But towards the end of that first set I just started feeling more and more pain. It was too much, I guess, to handle for me at the moment. Unfortunate ending, but I tried.
“If I won the first set, maybe I would try a few more games, half a set, maybe a set. I don’t know. It was getting worse and worse.
“I knew even if I won the first set, that it’s going to be a huge uphill battle for me to stay physically fit enough to stay with him in the rallies, you know, for another God knows what, two, three, four hours.
“I don’t think I had that, unfortunately, today in the tank.”

“The very first thing I want to say is please don’t boo a player when he goes out injured,” said Zverev, who was forced to retire from a French Open semi-final against Rafael Nadal after tearing ankle ligaments three years ago.
“I know that everybody paid for tickets and wants to see a five-set match but you have got to understand Novak Djokovic is somebody that has given this sport for the past 20 years absolutely everything in his life.
“He has won his tournament with an abdominal tear, won this tournament with a hamstring tear, if he feels he cannot continue a tennis match, he cannot continue a tennis match. So please guys, be respectful. Show some love for Novak as well.”

Despite his World No 1 ranking, Jannik Sinner trails the head-to-head to Alexander Zverev with the German winning four of their six previous meetings.
While Sinner was the victor the last time they played - in three tight sets in the Cincinnati semi-finals last year - Zverev has won the previous four, including in the last-16 of the US Open in 2023.
That five-set match was the last time Sinner lost a grand slam match on a hard court, with the Italian winning the Australian Open and US Open titles in 2024.

Sinner on what he was going through physically in the third set.
“A lot of tension today, slightly cramping. He was too suffering a little but in his legs so I tried to move him around. These matches can go long; for three sets two and a half hours is a long time. So I’m happy to finish in three. Let’s see what’s coming Sunday.”

The defending champion marches on! Jannik Sinner wins his 13th match in a row at the Australian Open and defeats Ben Shelton in straight-sets to book a clash with Alexander Zverev on Sunday.
Sinner faced challenges at the end of the first set and during the third, when he appeared to struggle with cramp, but the World No 1 responds to tough moments so impressively and he raced over the line. Shelton was outmatched and the American is dismissed 7-6 6-2 6-2.

Does that just about sum up the match? After limping back to his seat in the previous changeover, Sinner returns to the court and wins eight points in a row. He holds serve and then breaks Shelton to love, with the American throwing away the double-break with the double-fault.
That’s a delight for Sinner, who is receiving more treatment to his right thigh but stands one game away from a return to the Australian Open final.

The Italian was very stiff as he got back to his position, but appeared to be fine during the rallies as he battled back to deuce. In what felt like a key game Shelton then made the double fault!
Shelton nets. Sinner breaks. But limps back to his seat. That’s a huge boost for the Italian, who will want to get this wrapped up as soon as possible now.

An early break would help Shelton’s weary legs but he can’t take it in Sinner’s opening service game. The American had a look at Sinner’s second serve but nets on the backhand and immediatly drops his racket in disgust.

Yep, no problems at all for Jannik Sinner as he closes out the second set with an ace and love-hold.
The World No 1 took complete charge after somewhat stealing the first set and winning the tiebreak. He won almost all of his points behind his first serve, while taking Shelton’s apart on the returns.
That was a display of authority that leaves Shelton facing an almost impossible task. The 22-year-old is also having his legs rubbed down, and looks to be struggling with cramp.

Oh dear. Shelton unravels in the tiebreak, losing the first five points in a row either to poor errors from the baseline or questionable shot selection. Sinner looks completely calm and plays with Shelton as if on a string to move 5-0 up.
Shelton gets a couple of points back behind serve, but then Sinner gets the job done. As he so often does, Sinner locks in on the tiebreak and raises his level, with Shelton unable to match it. The American had to finish the set off behind serve, but gave Sinner a chance and he took it.

Shelton nets on the serve-and-volley! Awesome return out wide from Sinner, and there’s the forehand strike! Shelton can’t reply. Sinner gets back on serve to force the tiebreak! Shelton sees two sets points come and go, just like that.

“He’s built this aura up from beating everyone,” De Minaur said. “It’s not like he’s just had a good week here or good week there. He’s just beaten everyone.
“I think the best way to describe it is the fact that he was able to play Novak here and play pretty flawless, and, again, not give him too many games, right? Novak out here is probably the best player to have ever played on these courts, right?
“The fact that he’s got this top level that he can do this to players, it’s pretty tough. You go into the match, and you know it’s going to be a battle, it’s going to be tough, you’re going to try different things.
“But then you’re an hour and 30 in, and you’re struggling to win games, and you’re trying to find ways to get on the board. It’s pretty surreal.”
