In this year's three majors, he is 21-0, with victories in finals over Daniil Medvedev, 25, in Australia, Stefanos Tsitsipas, 22, in France, and now Berrettini, 25.

On Sunday, Djokovic made merely 21 unforced errors, while accumulating 31 winners. Djokovic's returns are as good as anyone's, ever. His two-handed backhand is a constant threat. His ability to anticipate and reach shots is remarkable. And he does whatever it takes: Djokovic won 34 of 48 points when he went to the net, 7 of 9 when he serve-and-volleyed.

What sets him apart above all is a quality stats can't trace: "The ability to cope with pressure," he called it.

When the tension and heart rate ratchet up, Djokovic is either impervious to that sort of thing — or plays as if he is.

It's the experience. The grit and guts. The talent and hard work. This has been a year of dominance by Djokovic, on top of a decade of success.
