Felix Auger-Aliassime moved into the U.S. Open semifinal on Tuesday when Spanish teenager Carlos Alcaraz retired due to an abductor injury while trailing 6-3, 3-1.

The 18-year-old Spaniard showed no signs of distress as Auger-Aliassime took the opening set but after the Canadian broke to open the second Alcaraz slumped. During the first changeover of the second set, Alcaraz called for the physiotherapist but did not receive any treatment. A game later, however, the Spaniard turned and indicated he could not go on.

"It's really tough to end a great tournament like this," said Alcaraz. "I had no choice to still playing.

"First of all I have to take care of my body.

"I didn't feel good to still playing, so I had to retire," he said.

Coming off gruelling back-to-back five-set matches, including a third-round win over Stefanos Tsitsipas, Alcaraz stepped onto the court with both legs heavily strapped and seemed to lack the power and energy that had carried him to the quarter-finals.

"I didn't see it coming. It's unfortunate to finish like this," said Auger-Aliassime. "I didn't really see anything.

"Either I was too focused on my game or I'm not seeing things," he added.

Auger-Aliassime becomes the first Canadian man to reach the U.S. Open semifinal, where he will take on second seeded Daniil Medvedev of Russia.

The 21-year-old joins compatriot Leylah Fernandez, who booked her spot in the women's last four earlier in the day by beating Elina Svitolina.

"It's great for Canada. It's great for Quebec," said Auger-Aliassime. "I never thought a day like this would come.

"Both a little girl and a little boy from Montreal, both at the same time in the semifinal of the US Open.

"It's special. I hope the people back home appreciate the moment also. It's great but it would be amazing if we were both in a final," he said.
