The 2021 Nitto ATP Finals draw has been made

Groups for the 2021 Nitto ATP Finals were announced Thursday night at the tournament draw ceremony in Turin.

The groups are:

Green Group Novak Djokovic Stefanos Tsitsipas Andrey Rublev Casper Ruud

Red Group Daniil Medvedev Alexander Zverev Matteo Berrettini Hubert Hurkacz

Held for the first time in Turin, Italy, the Nitto ATP Finals will run 14-21 November at the Pala Alpitour.

Djokovic, who last week clinched the year-end No. 1 FedEx ATP Ranking for a record-breaking seventh time, will look to match Roger Federer's record of six Nitto ATP Finals titles.

Medvedev is the defending champion after last year claiming the title with a perfect 5-0 record, including a historic hat-trick of wins over the world's Top 3 players (Djokovic, Rafael Nadal and Dominic Thiem), a first in the 50-year history of the event.

The doubles groups for the 2021 Nitto ATP Finals are set.

The groups are:

Green Group Nikola Mektic and Mate Pavic Marcel Granollers and Horacio Zeballos Ivan Dodig and Filip Polasek Kevin Krawietz and Horia Tecau

Red Group Rajeev Ram and Joe Salisbury Pierre-Hugues Herbert and Nicolas Mahut Juan Sebastian Cabal and Robert Farah Jamie Murray and Bruno Soares

Five players competing have lifted the trophy before, with Herbert and Mahut the only pair to do so together (2019). Granollers was victorious with Marc Lopez in 2012, Tecau triumphed alongside Jean-Julien Rojer in 2015 and Mektic earned the crown with Wesley Koolhof last year.

Mektic and Pavic, who have claimed nine tour-level titles this season, clinched the year-end No. 1 FedEx ATP Doubles Team Ranking last week. This is their first year competing as a duo.
