Djokovic, 36, took less than 90 minutes to beat Carlos Alcaraz 6-3, 6-2 in a match between the top two players in the rankings Saturday night, after Sinner had earlier dispatched Daniil Medvedev 6-3, 6-7 (4), 6-1.
Djokovic is currently tied with Roger Federer with six titles at the season-ending tournament for the year’s top eight players, while Sinner is the first Italian player to reach the final.
Earlier this week, Sinner recorded his first-ever victory over Djokovic, who will also have to contend again with a passionate, partisan crowd — including the orange-clad “Carota Boys” — that showed Sinner plenty of support Saturday. With many fans chanting his name between points, the 22-year-old Sinner raised his arms to the joyous crowd after serving the match out to love against 2020 champion Medvedev.
“It is a privilege to have this kind of pressure,” Sinner said. “The crowd has given me so much energy.
“It was a very difficult match. He started better than me, then I somehow managed to get the break and then I felt a bit better.”
Sinner has won all four of his matches at the ATP Finals, including that mesmerizing victory over Djokovic.
