Canada clinched their place in the Davis Cup quarterfinals on Saturday thanks to Felix Auger-Aliassime's win in singles, while Croatia improved their chances of reaching the last eight with a 3-0 sweep of Argentina. Auger-Aliassime backed up his defeat of new world number one Carlos Alcaraz with a 6-3, 6-4 victory against Serbia's Miomir Kecmanovic, although Serbia won the tie 2-1 in Valencia to keep their own hopes alive. Serbia's Laslo Djere downed Gabriel Diallo 6-2, 6-2 in the opening singles match before Auger-Aliassime's win guaranteed Canada a top-two finish in Group B. "I feel this whole event my level has been really good," said Auger-Aliassime, the world number 13. "I'm really happy where my game is at. To come out and play this way, get the win, it's very good for me personally. I'm just really happy for the team. I'm really happy that I came and played with the level I did to get Canada through the quarters," he added.
