Canadian 12th seed Felix Auger-Aliassime has progressed to his first-ever major semi-final after Spanish teenager Carlos Alcaraz's shock withdrawal in the second set of their US Open quarter-final.
Alcaraz, who had won back-to-back five-setters to reach the last eight, retired 68 minutes into Tuesday's quarter-final trailing 6-3 3-1.
The result means Auger-Aliassime, who has never won an ATP Tour title, will take on second seed Daniil Medvedev in the semi-finals on Friday.
The Spanish 18-year-old was attended to by a physiotherapist 2-1 down in the second set and was seen pointing to his upper right leg without receiving any discernible treatment.
Alcaraz had not shown any major signs of injury prior to that yet withdrew following the completion of the next game with the Canadian in control.
Beyond the unusual circumstances, the victory marks a major milestone for 21-year-old Auger-Aliassime, who joins countrywoman Leylah Fernandez in reaching this year's US Open semi-finals.
This marks the second time that two Canadians have reached the semis in the same grand slam, joining Milos Raonic and Eugenie Bouchard at Wimbledon in 2014.
Auger-Aliassime, whose best previous major result was reaching this year's Wimbledon quarter-finals, was strong on his first serve early, delivering 6-1 aces in the first set.
Leading 3-2, the Canadian broke Alcaraz at the third attempt, before both players held to give Auger-Aliassime the chance to serve for the set at 5-3.
In a dramatic game, Auger-Aliassime offered up three break points trailing 0-40, only to rally and win the game to close out the set in 44 minutes, aided by 12 winners.
The 21-year-old broke Alcaraz in the first game of the second set, before Alcaraz's premature retirement, handing the Canadian victory.
Data Slam: First of a new men's generation
Auger-Aliassime becomes the first male born in the 2000s to reach a Grand Slam semi-final, marking a new generation in men's tennis.

Raducanu named in Great Britain team for Billie Jean King Cup
Emma Raducanu has been named in Great Britain's team for the Billie Jean King Cup finals.
The 2021 US Open winner will be joined by Katie Boulter, Harriet Dart, Heather Watson and Olivia Nicholls for the event in Malaga.
Britain defeated France in April to qualify for the knockout stage, with four of the aforementioned five - Watson the exception - taking part.
Captain Anne Keothavong named her five-member team on Monday ahead of the showpiece, which runs from November 13 to 20.
"We are really looking forward to the finals in Malaga after qualifying following our fantastic weekend in France in April," Keothavong said.
"Our team have created excellent memories and put in outstanding performances in this competition in recent years.
"We will relish the opportunity. There is still a lot of tennis to be played, and changes can be made up until the day before our first match."
All 12 teams announced their line-ups on Monday, with Iga Swiatek and Coco Gauff notable names not included for Poland and the United States respectively.
World number one Swiatek and world number six Gauff feel they are unable to compete due to a quick turnaround in events to end the year.
US Open semi-finalist Emma Navarro is also out of the USA squad.
Canada dump Great Britain out of Davis Cup as Shapovalov, Auger Aliassime win
Canada beat Great Britain to ensure their progress to the Davis Cup Final 8 on Sunday, with Denis Shapovalov beating Dan Evans and Felix Auger Aliassime overcoming Jack Draper.
Canada needed just one point from their final group-stage tie, and Shapovalov did the honours at the first time of asking by beating Evans 6-0 7-5.
Shapovalov won 100% of first-serve points as he dominated an opening set that lasted just 27 minutes, and though Evans came back into the encounter in the second set, a break in the final game sealed the deal for Shapovalov.
With Canada's progress secured, Auger Aliassime then added some gloss by overcoming US Open semi-finalist Draper 7-6 (10-8) 7-5 in a fiercely contested affair.
British pair Neal Skupski and Henry Patten beat Gabriel Diallo and Alexis Galarneau 7-6 (7-4) 6-4 in the doubles, but it was of little consequence with their elimination already certain.
Argentina joined Canada in qualifying from Group D with a sweep of Finland, while Italy finished top of Group A in Bologna, thanks to the efforts of Flavio Cobolli.
He beat Tallon Griekspoor 7-6 (7-4) 4-6 6-3 as the Netherlands were forced to settle for second, after Matteo Berrettini had put the defending champions in the driving seat with a 3-6 6-4 6-4 win against Botic van de Zandschulp.
World number one Jannik Sinner was present to support Berrettini, embracing him after he capped his fightback by converting match point.
Australia and Spain had already sealed qualification from Group B prior to Sunday's matches, while the United States and Germany had clinched their progress from Group C.
The Davis Cup Final 8 will take place in Malaga between November 19 and November 24, with Italy hoping to become the first team to defend the title since the Czech Republic in 2013.
'Not my goal at all' - Djokovic not committing to ATP Finals appearance
Novak Djokovic "can't say" if he will compete in the upcoming ATP Finals in November as he becomes more selective about which tournaments he participates in.
The Serbian has struggled with injuries and a lack of form in 2024, and he will finish a calendar year without a grand slam title for the first time since 2017.
His last major triumph came at the US Open last year, but he failed to defend his crown, suffering a shock early exit to Alexei Popyrin in the third round at Flushing Meadows.
Djokovic is just one grand slam trophy away from becoming the outright record holder, currently sitting level with Margaret Court on 24 titles.
He reached the Wimbledon final in July, only to lose out to Carlos Alcaraz, though he did win his first Olympic gold in Paris by beating the Spaniard the following month.
The 37-year-old is currently representing Serbia at the Davis Cup and stressed that he will be prioritising certain tournaments over others.
"Torino is not my goal at all, to be honest, I am not chasing ATP Finals, I am not chasing the rankings etc," he told Serbian reporters after beating Greece's Ioannis Xilas on Saturday.
"As far as I am concerned, I am done with those tournaments for my career. Whether I will play other tournaments this year or in the future, I can't say right now.
"My main priorities are playing for the national team and slams, everything else is less important.
"Weeks like these represent another motivation, they inspire me to keep going, they awake those butterflies in my belly.
"I thought that I would never have to seek motivation anywhere, it all used to come naturally – automatically – but that has not been the case in the last few years.
"In order to prolong my career, I need to enjoy, I need to choose wisely tournaments I am going to play."
Following the Davis Cup, Djokovic will play in an exhibition tournament in Sofia and in the ATP 1000 event in Shanghai at the start of October.
"After that [Shanghai], I am going to see what I am going to do," Djokovic added.
"Usually in my career I used to have my schedule ready six months in advance, but nowadays, that's not the case. Now it's more spontaneous.
"Firstly, I need to physically, emotionally and mentally rest in order to even start thinking what I want to do next, in what way, how much and where."
