The Italian, who's rapidly moving towards all-time great status with his fifth grand slam title at the age of just 24, had to roar back from a set down to nullify the threat of newly-minted French Open champion Zverev before prevailing 6-7 ( 7-9) 7-6 (7-2) 6-3 6-4 on a warm, blustery Centre Court on Sunday.
World No.1 Sinner, who'd won his nine previous clashes against the No.2 seed, suddenly found their first grass-court meeting to be a more complicated affair as the German, buoyed with confidence since his Roland Garros success, took the opening set with a glorious forehand winner after a stellar-quality tiebreak.
But after finding a read on Zverev's monster delivery to really hit his stride in a second-set breaker and level proceedings, there was a kind of inevitability to Sinner's remorseless progression as he increasingly pressurised his opponent's serves until the German cracked once in each of the last two sets.
It was another magnificent display by the dominant champion, who was back to winning ways a month since his sensational heat-related exit in Paris when he suffered one of the great grand slam meltdowns in collapsing to defeat to Juan Manuel Cerundolo in the second round.
In their 15th meeting, with Sinner leading 10-4, Zverev gave as good as he got in the first two sets, and it was still in the balance at 3-3 in the third when Zverev finally earned his first break point, only for Sinner to save it audaciously with a drop shot that wrong-footed the German and sent him sprawling to the ground.
Zverev stayed down on the turf, having appeared to wrench his knee, until Sinner came round the net to sportingly check on him, and while the towering German rose gingerly while seemingly okay, the Italian then quickly retained serve before going on the attack again.
The key moment came next game with Zverev at break point down. In a baseline rally, this time it was the world No.1 who slipped, but Sinner somehow still managed to scramble to his feet mid-rally and win both point and game, leaving the German to hurl his racquet away in disgust after sending his final shot long.
Sinner went for the kill at 3-3 in the fourth, eking out the key break from which there was no way back for Zverev, despite his brilliant efforts to win a spectacular point while the Italian was serving for the match.
But in front of an enthralled Royal Box, featuring Prince William, wife Kate and two of their children, as well as Hollywood stars Dustin Hoffman, Nicole Kidman and Ben Stiller, Sinner wasn't to be denied, crushing one more thunderous forehand, his 58th winner, to lift his sixth title of a magnificent year, but only his first slam of 2026.Â
After flopping on to his back in joy, Sinner, who was presented with his trophy by Kate, Princess of Wales, declared: "Amazing...there's no better place to play tennis. You gave me the most special feeling that any tennis player could ever feel like."
After joking to his rival at the trophy presentation "Jannik, first of all, I don't really like you any more!" after his 10th-straight defeat, Zverev could only admit more seriously: "He showed once again why he's the best player in the world."
And even though Sinner's great rival Carlos Alcaraz has been out of the picture with a wrist injury, there really can be no argument about that verdict. The only question that remains is how many slams this extraordinary champion will go on to claim.
