Stefanos Tsitsipas battled back from a set down against Dominic Thiem to win the ATP Finals title, emphatically staking his claim as the leader of the next generation of aspiring global superstars.
The Greek 21-year-old, who won, 6-7 (6/8) 6-2 7-6 (7/4) on Sunday, is the youngest champion since Lleyton Hewitt in 2001 and the fourth first-time champion at the season-ending event in as many years.
It is Tsitsipas's third title of the season and comes a year after he was crowned champion at the Next Gen ATP Finals in Milan.
He has charmed the crowd at London's O2 Arena all week and earned his place in the final with an impressive straight-sets win against six-time champion Roger Federer.
"I can't sum up my emotions right now," said Tsitsipas.
"It's amazing to be remembered as the 2019 champion. It is a dream come true and the best way to end this match.
"I did get nervous at some points in the match but I managed to forget about how I felt and I had momentum in the tie-break which was really tight.
"My fighting spirit and me constantly trying to push myself to do better got me there in the end."
