Jannik Sinner stunned Novak Djokovic with wins in singles and doubles to send Italy through to a first Davis Cup final for 20 years.

Djokovic suffered an unwanted career first when he failed to convert three consecutive match points in a pulsating 6-2 2-6 7-5 singles loss against world number four Sinner.

It was Djokovic’s first defeat in a Davis Cup singles rubber since a retirement against Juan Martin Del Potro 12 years ago, ending a 21-match winning run.

Serbia had led 1-0 in the semi-final in Malaga thanks to Miomir Kecmanovic’s win over Lorenzo Musetti but Djokovic’s loss sent the tie to a deciding doubles contest.

Djokovic and Sinner lined up on opposite sides of the net for the fourth time in less than two weeks alongside Kecmanovic and Lorenzo Sonego respectively, and it was the Italian duo who clinched a 6-3 6-4 win to send their country through to a clash with Australia for the title on Sunday.

After Kecmanovic had backed up his fine showing against Britain’s Jack Draper by coming from a set down to defeat Musetti 6-7 (7) 6-2 6-1, the stage seemed set for Djokovic to send Serbia through to the final.

The confidence Sinner had gained from his group stage victory over Djokovic at the ATP Finals was negated by a convincing loss in the final but the world number one looked fatigued, perhaps more mentally than physically, during the first set.

Both men had headed straight from Turin to Malaga but Sinner is 14 years younger than his rival and he took full advantage of some uncharacteristic errors to reel off five games in a row.

It was another excellent atmosphere at the Palacio de Deportes Martin Carpena, befitting the sort of marquee clash that Davis Cup has not seen enough of over the last decade and more.

Djokovic had made winning a first title with Serbia since 2010 one of his big priorities and he showed more positive energy at the start of the second set, breaking for the first time to lead 3-1 after his opponent double-faulted.

A second break sent the contest to a deciding set, where it seemed a case of when rather than if Djokovic would find the breakthrough.

But Sinner refused to buckle, saving break points in two separate games prior to his remarkable renaissance at 4-5, when he won five points in a row from 0-40.

The missed opportunities seemed to play on Djokovic’s mind and, in a reminder that even the very best are not immune to pressure, the Serbian netted a routine shot to hand Sinner a break point and was then passed after an ill-advised serve and volley.

Moments later, Djokovic blasted a return long to the sounds of Italian jubilation and stunned Serbian silence, with Sinner saying: “It was an incredible match. We were one point away from being out of the competition but we are still here.”

Djokovic’s singles record in Davis Cup may be formidable but his doubles one is anything but, with only four wins from 11 previous matches.

None of the four players picked are regulars on the doubles circuit but the Italian duo looked much more at home in the format and broke Djokovic’s serve on the way to taking the opening set.

They were a break up early in the second, too, but this time Serbia came back and, having lost his cool with the British crowd on Thursday, here Djokovic began conducting the Italian jeers.

After Sinner saved four break points to hold for 3-3, another long game, this time on the Kecmanovic serve, resulted in a break for the pumped up Italian pair, and fittingly it was Sinner who served out the victory.

Tennis will never see a "big three" with the quality of Rafael Nadal, Novak Djokovic and Roger Federer again, believes Juan Martin del Potro.

The trio, who have combined for a total of 64 men's singles grand slam titles across a near-two-decade-long period of dominance, have come to define the sport's modern era.

Federer retired last year and while Nadal and Djokovic continue, both are well into the twilight of their careers, despite astonished continued success.

Del Potro, the 2009 US Open winner, also retired in 2022, and he thinks the trio's dominance is unlikely to be replicated going forward, even though he sees Carlos Alcaraz, Jannik Sinner and Holger Rune as three players who could possibly go on to enjoy great success.

"The only thing I lacked was being number one [in the ATP Rankings]," he said. "It was always a dream, and I always worked for it. I never made it because there was either Federer, or Nadal, or Djokovic.

"When I look at the rankings and the years of my career and who was fighting to be number one I see that it was beautiful that these were the ones who didn't let me make it, this dream."

"One day, the big three will end. We have Carlos Alcaraz, Jannik Sinner [and] Holger Rune, other young people who will mark the circuit.

"But for me, [for] many years, [it was] the big three. There will not be anything similar."

Del Potro reached a career high-mark of third in the ATP Rankings in 2018, with Andy Murray the only man other than Nadal, Federer or Djokovic to top the charts between 2005 and 2021.

Juan Martin del Potro was reduced to tears in what he expects to be his final tennis match as the former US Open champion bowed out of the Argentina Open.

The 33-year-old Argentinian lost 6-1 6-3 to fellow Argentinian Federico Delbonis in Buenos Aires, having come back from four rounds of knee surgery to get back on court.

He saved seven of 12 break points in a determined effort against Delbonis, but Del Potro, who had been on the injured list since June 2019, was in no shape to compete for victory over his compatriot.

One of the most popular players on the tour, who might have achieved many more great things had wrist and knee trouble not played him over the last decade, Del Potro bid an emotional farewell.

The moment got to Del Potro as he prepared to serve at 5-3 down in the second set. His emotions spilled out, with a towel failing to mask his tears as a passionate crowd rallied behind him, chanting: "Ole, ole, ole, ole, Delpo, Delpo."

A fan carried a flag bearing the message: "The Tower of Tandil keeps fighting. Thank you." Tandil is Del Potro's home city.

After the match, Del Potro said: "The truth is that this is a moment I never wanted to come. Health leads me to have to make a decision: I made too much effort in these two and a half years.

"Sometimes I can lose. I do not have the strength that everyone believes. I think I fulfilled all the dreams in tennis and the most difficult thing to achieve, which is the affection of the people.

"I feel like I've given it all. This is a day I never wanted to come, but I'm going to remember it for the rest of my life."

He was relieved to be leaving on his own terms, saying: "Now I am calm because my last match was possibly on the court and not in a press conference. I will always remember this."

Del Potro, whose US Open triumph came when he beat Roger Federer in a sensational 2009 final, has accepted a wildcard to the upcoming Rio Open, but he signalled he is unlikely to now take that up.

"Yes, I was planning to go to Rio," he said, quoted by La Nacion. "But... I think I already gave everything until the last point."

Del Potro was an Olympic silver medallist in 2016, beaten in the Rio final by Andy Murray, and later in the same year he helped Argentina win the Davis Cup.

It was fitting that Delbonis, who won the decisive rubber against Croatia after Del Potro was victorious in both his singles matches, was the man on the other side of the net on Tuesday. He and Del Potro shared a long, affectionate hug at the net at the end of the match.

Del Potro's mother, Patricia, was among those in the crowd. The ATP said it was the first time she had attended one of his matches. She was pictured embracing her son off court after the match ended.

Other matches happened in Buenos Aires on Tuesday too, a highlight being Brazilian Thiago Monteiro's 6-3 6-3 win over seventh seed Albert Ramos-Vinolas.

At the Dallas Open, first-round winners included Jack Sock, Jordan Thompson and Liam Broady.

Juan Martin del Potro will undergo knee surgery for the fourth time but retains hope of playing at the Olympic Games in Tokyo.

Del Potro, who was a career-high world number three in August 2018 and still in the top 10 fewer than two years ago, has not appeared on the ATP Tour since withdrawing from the Queen's Club Championships in 2019.

The 2009 US Open champion had his first procedure after falling at the tournament in London and another followed in January 2020.

The third operation came last August as pain persisted, but the issue still has not been eradicated.

However, Del Potro said in an Instagram post on Monday that the death of his father earlier this year had motivated him to continue pursuing a return to the court.

The 32-year-old, who won bronze for Argentina at the 2012 Olympics and silver four years later, will go under the knife again in Chicago on Tuesday.

"We've tried conservative therapy but the pain is still there," he wrote.

"[Doctor Jorge Chahla] knows I want to play tennis again and be able to play the Olympics, so we agreed that surgery should be done as soon as possible.

"Of course, these last few weeks weren't easy for me. Everything's so hard since my father's passing.

"But also, I feel the strength he sends me from above. I had this day in which I woke up and called the doctor. I knew I had to try again.

"I hope I can overcome this painful situation. I won't stop trying. Of course, your messages and best wishes are always welcomed. Thanks for the love."
