Novak Djokovic is covered in sweat, he’s already sweated through his new green polo shirt, and they are four games into the new set.
He managed to hold serve that last game was but hunched over catching his breath at times. How can he keep this pace up? Jannik Sinner looks tired but not nearly as gassed.

Still, Djokovic is still on top.
It’s 6-3, 3-6, 2-2 with Sinner serving.
As Sam McClure noticed at RLA: Novak is showing the first signs of physical pain in the fourth game of the third set. He’s keeling over between points. He still has, by the way, pulled off one of the great forehand passing shots of the match in this game. But the physical nature of the contest appears to be getting to the 24-time grand slam champion.
