Tsitsipas beats Thiem in 3 sets to win ATP Finals title

He also leaves London with $2.6 million in prize money for this win and joins a group of young players — including last year’s ATP Finals champion Alexander Zverev and U.S. Open runner-up Daniil Medvedev — who are seen as the top up-and-coming talents and challengers to the sport’s Big Three of Roger Federer, Novak Djokovic and Rafael Nadal.

The Greek has already grown quite the fan base, partly because of a Bjorn Borg-style haircut and partly because of an aggressive playing style that is a bit old-school with frequent forays to the net.

”He's great for tennis, because he has a very attractive game style, one-handed backhand, comes in a lot,” Thiem said. ”It's great that he's up on the top. It's great that he's going to fight for the big titles in the future. I'm 100% sure of that. I'm also very sure of the fact that I can challenge him in every single match we're going to play. … I really hope that we're going to have a lot of big matches coming, the two of us.” Thiem beat both Federer and five-time winner Djokovic in the group stage but lost another big final after twice finishing runner-up to Nadal at the French Open.

This one was much closer than his losses to Nadal, though, which made it tougher to swallow.

”That's why it's probably mentally the most brutal sport existing, because you can play such a great match and end up losing in the championship match,” Thiem said. ”From that point of view, it's a very disappointing loss, very hard to digest. But on the same hand, I had some amazing wins also.” It is the fourth year in a row that there is a first-time champion at the ATP Finals, following wins by Andy Murray in 2016, Gregor Dimitrov in 2017 and Alexander Zverev last year.

Earlier, French duo Nicolas Mahut and Pierre-Hugues Herbert won the doubles title by beating Raven Klaasen of South Africa and Michael Venus of New Zealand 6-3, 6-4.
