Tsitsipas overcomes Medvedev in battle of ATP Finals debutants
Stefanos Tsitsipas battled to a two-set victory over Daniil Medvedev in the duo’s first-ever ATP Finals match in London.
"I had goosebumps today, playimg on this court that I dreamed of playing on, it's pure joy," Tsitsipas said.
"This was one of my most important victories of my career so far. Everything worked pretty well.
"Not easy coming in knowing you have lost five times but I made a deal with myself that I would keep trying."
After both enjoying breakthrough seasons on Tour, the match-up proved to be a tight affair between Tsitsipas and Medvedev.
There was just one break-point opportunity for Australian Open semi-finalist Tsitsipas in the opening set - which he failed to convert - before it headed to a tie-break.
And it was the Greek who won it 7-5 despite Medvedev twice recovering from a mini-break down.
In the second set, Medvedev saved a further two break points but at the fourth time of asking, Tsitsipas broke to lead 5-4 before closing out the match.
Tsitsipas did not offer Medvedev, the losing US Open finalist, a single break point during their 1hr43min encounter.
