In a perfect echo of the triumph that first propelled him to the number one spot in 2022, Alcaraz's second New York title lifted him back to the top of the world rankings as the 22 year-old Spaniard displaced Sinner and took his Grand Slam trophy haul to six.

As grey clouds hovered over the iconic Arthur Ashe Stadium, Alcaraz continued to deliver the sunshine tennis that has lit up Flushing Meadows over the last fortnight, consolidating an early break by faking a drop to hit a winner that wrong-footed Sinner.

He beamed after pulling off an outrageous half-volley at the net and wrapped up the opening set shortly afterwards, finishing it off with a big serve that Sinner crashed into the net as the Italian's metronomic precision briefly deserted him.

With U.S. President Donald Trump watching from a luxury box in the stands and adding another layer of spectacle to the third straight Grand Slam final between the duo this year, Sinner hit back to take the next set after saving an early break point.

After missing a few steps to drop his first set of the championship, Alcaraz blasted his way to a 5-0 advantage in the third set before Sinner got on the board, and the Spaniard closed it out with a monster serve.

Sinner conjured up two breathtaking volleys in the opening game of the fourth set to roaring applause and held serve after being pushed to the limit again, but he cracked under pressure and handed the crucial break to Alcaraz in the fifth game.

Resembling a flamingo in full flight in his bright pink vest, Alcaraz soared ahead to secure the victory on his third match point and celebrated by raising his fists before a warm embrace with his rival and wild celebrations with his team.
