Berrettini joins Jannik Sinner on the bench, blunting the hopes of a strong Italian team.

Carlos Alcaraz will seek revenge against the red-hot Canadian in Basel Saturday.

As a crop of contenders aim to bolster their ATP Finals bids, the already-qualified Alcaraz looks to get some momentum going again.

Sinner bid farewell to his fellow Northern Italian, who will hang up his racquets at the Ortisei Challenger.

"It's hard to put into words how truly special it was for me to spend the day and ski with one of the greatest to ever do it," said the Italian of the U.S. Olympic champion.

The Italian aims to return in time for the Erste Bank Open in Vienna after incurring an injury in Sofia.

"This kind of level was very high for sure," the Italian said. "It was a good match. I hope also for the spectators."

Alcaraz’s five-hour, 15-minute victory over the Italian was also the second-longest match in US Open history, period.

Can the home crowd help propel either American into a breakthrough major semifinal on Wednesday?

Born nine years and an ocean apart, the Argentine and Italian will converge on the courts of the Western & Southern Open as they look to celebrate the big day with match wins.
