2 – Number of singles debutantes at this year’s ATP Finals – No.5-seeded Felix Auger-Aliassime and No.8-seeded Taylor Fritz.

6 – Number of doubles debutantes at this year’s ATP Finals – Neal Skupski (paired with Wesley Koolhof), Austin Krajicek (paired with Ivan Dodig), Thanasi Kokkinakis and Nick Kyrgios, Marcelo Arevalo (paired with Jean-Julien Rojer), Lloyd Glasspool and Harri Heliovaara.

3 – Number of former Nitto ATP Finals champions in the Red Group, which includes five-time champ Novak Djokovic, 2020 champ Daniil Medvedev and 2019 Stefanos Tsitsipas.

2015 – Djokovic has not won the Nitto ATP Finals since he claimed his fifth title – and fourth in succession – in 2015.

$14,750,000 – Total prize money on offer at this year's event.

7 – Number of nations represented in singles.

8 – Number of nations represented in doubles.

3 – Number of players with a shot at the ATP’s year-end No.1 ranking this year. If Nadal wins the tournament or goes 4-1 as runner-up (and Tsitsipas does not win the title) he will rise to No.1. If Tsitsipas wins the title undefeated (5-0) he will win the title.

If neither scenario occurs, Carlos Alcaraz will become the youngest player – and first teenager – in ATP history to claim the year-end No.1 ranking.

6 – The all-time record for Nitto ATP Finals titles, held by Roger Federer. Djokovic bids to tie the Swiss great this season.

11 – Number of appearances Nadal has made at the ATP Finals. The Spaniard has yet to win a title but has reached the finals on two occasions (2010 and 2013). The 22-time major champion is 20-16 lifetime at the season-ending championships.

41-17 – Djokovic's career record at the ATP Finals. The 21-time major champ makes his 15th appearance.

30 – Roger Federer remains the oldest champion at the ATP Finals. The Swiss won his last title in London in 2011 as a 30-year-old.

36 – Nadal is the oldest participant in this year’s event, followed by Djokovic, who is 35. The other six participants are 26 or younger.

60 – Tsitsipas leads the ATP with 60 wins on the season. Felix Auger-Aliassime (56) is the only other participant with more than 50 wins in 2022.

27 – ATP Finals debutante Felix Auger-Aliassime leads the tour in indoor wins with 27 wins against five losses in 2022.
