Auger-Aliassime advances after Alcaraz retires in second set
Montreal's Felix Auger-Aliassime joined fellow Canadian Leylah Annie Fernandez in the semifinals on the men's side later Tuesday after his opponent Carlos Alcaraz of Spain retired in the second set.
The 21-year-old Auger-Aliassime was up 6-3, 3-1 when 18-year-old Alcaraz waved over his trainer before calling an end to his tournament.
Auger-Aliassime, the No. 12 seed, will face No. 2 seed Daniil Medvedev in the semifinals.
Medvedev, a 25-year-old from Russia, earned a spot in the final four at Flushing Meadows for the third consecutive year by stopping the surprising run of Dutch qualifier Botic van de Zandschulp 6-3, 6-0, 4-6, 7-5.
Earlier on Tuesday, Fernandez beat No. 5 seed Elina Svitolina in a third-set tiebreak to advance to the semis. She will take on Aryna Sabalenka, who defeated Barbora Krejcikova in the other women's quarterfinal matchup on Tuesday.
