Djokovic, Tsitsipas in Green Group at Nitto ATP Finals

The tournament, scheduled to run from November 14 to 21 at the Pala Alpitour here, will see the 'Red Group' being led by defending champion from Russia Daniil Medvedev. The group also has Germany's Alexander Zverev, Italian Matteo Berrettini and Poland's Hubert Hurkacz.

Medvedev, who defeated Djokovic at the 2021 US Open and stalled his progress to the calendar Grand Slam, had claimed the title last year with a perfect 5-0 record, including a historic hat-trick of wins over the world's Top-3 players -- Djokovic, Spain's Rafael Nadal and Dominic Thiem of Austria -- a first in the 50-year history of the event.

The groupings were announced on Thursday night at the tournament draw ceremony here.

Djokovic, who last week clinched the year-end No. 1 ATP Ranking for a record-breaking seventh time, will look to match Roger Federer's record of six Nitto ATP Finals titles. The Serb is in imperious form, having defeated Medvedev in the Paris Masters final recently following the US Open setback.

Green Group: Novak Djokovic, Stefanos Tsitsipas, Andrey Rublev, Casper Ruud.

Red Group: Daniil Medvedev, Alexander Zverev, Matteo Berrettini, Hubert Hurkacz.
