The season-ending ATP Finals is upon us once again with eight contenders vying for glory at London’s O2.

Here, we look at the runners and riders as the 2019 campaign comes to a conclusion.

The Spaniard, who ended the 2018 season early due to injury, has returned in 2019 playing some of the best tennis of his career. In compiling a 51-6 match record, he captured four trophies, including a historic 12th title at Roland Garros and a fourth US Open. He has never won the ATP Finals and holds a poor 16-13 record at the tournament.

4. Daniil Medvedev (Rus) 5705

What a year it’s been for the 23-year-old Russian. A 59-18 record including two Masters 1000 titles. He won 29 of 32 matches as he arrived in Paris on a nine-match winning streak before suffering a shock exit to Jeremy Chardy. The US Open finalist will be making a maiden appearance at the season-ending event.

6. Stefanos Tsitsipas (Gre) 4000

TitlesEstorilMarseille

Tsitsipas, 21, has notched up impressive wins over Nadal, Djokovic and Federer in the same season as well as defeating the Swiss legend en route to the Australian Open semi-finals. He is 50-24 overall this year with the Greek ready to make his maiden appearance in London.

7. Alexander Zverev (Ger) 2945

TitlesGeneva

The 22-year-old German will make his third straight appearance in the field where he will be defending his crown. There has been a lack of highlights to Zverev’s year compared to 2018, but he has a chance to redeem his season by winning in the capital again.
