Auger-Aliassime into ATP Finals last four, Sinner unbeaten

TURIN, Italy :Canada's Felix Auger-Aliassime reached the last four of the ATP Finals with a 6-4 7-6(4) round-robin win over two-times winner Alexander Zverev on Friday and Jannik Sinner extended his indoor hardcourt unbeaten run by beating American Ben Shelton.

Germany's Zverev and Auger-Aliassime both defeated Shelton and lost to Sinner to set up a winner-takes-all clash for the runners-up spot in the Bjorn Borg Group and the Canadian clinched a place in Saturday's semi-final against world number one Carlos Alcaraz.

"You want to be in the final but I'll have to go through a great player to do that," Auger-Aliassime said.

"I will take my chance if I have it."

Zverev was left to rue his failure to take any of his seven break points against Sinner, and it was a similarly frustrating story against the Canadian.

The German held break points in both sets but again could not make them count, and the Canadian broke Zverev at 5-4 up to take the first set, before going on to win the second set tiebreak.

Auger-Aliassime was put under pressure in the opening set, saving break points at 2-2 and 4-4, while Zverev came back from 0-40 down only to lose serve and hand the Canadian the set.

Zverev spent much of the second set gesturing to his team, with Auger-Aliassime winning his first two service games to love before both players were guilty of throwing away chances to break.

Auger-Aliassime let slip a 2-0 lead in the tiebreak, but when Zverev stepped up to serve at 4-5, the Canadian came through to earn consecutive minibreaks and send the German home.

SINNER STAYS UNBEATEN

Sinner is unbeaten in 29 matches on indoor hardcourt after a 6-3 7-6(3) victory over Shelton in their dead rubber round-robin match.

There was a relaxed atmosphere in the
