Stefanos Tsitsipas will make his fourth consecutive appearance at the season finale (5-4 record). Three years ago, he went 4-1 at The O2 in London and beat Dominic Thiem in the Nitto ATP Finals title match.
The Greek has enjoyed a consistent season from early on, having made a quick start in Australia. There, Tsitsipas advanced to the semi-finals of the Australian Open before reaching the final in Rotterdam just two weeks later.
Tsitsipas made his biggest splash of the year at the Rolex Monte-Carlo Masters, where he successfully defended his title to claim his second ATP Masters 1000 trophy. He continued to excel at that level by reaching the championship match in Rome and Cincinnati, while also lifting an ATP 250 trophy in Mallorca.
