Stefanos Tsitsipas will meet Dominic Thiem in today's showpiece to decide who will be crowned winner of the 2019 ATP Finals.
The 21-year-old beat Roger Federer in straight sets in the first semi-final on Saturday, clinching a 6-3, 6-4 success over the six-time champion after a ruthless display.
Tsitsipas, making his debut in the Finals, will face Thiem next after the Austrian came through his semi-final against Alexander Zverev.
Zverev won the tournament last year after beating Novak Djokovic in the final but faced a difficult test against Thiem, who had defeated both Djokovic and Federer in Group Bjorn Borg.

Prediction: Tsitsipas in two sets
Tsitsipas showed just how strong he was going into the semi-finals by winning his first two matches and, having already qualified, took Rafael Nadal all the way in a three-hour marathon.
To beat Federer in the way he did, with no obvious weaknesses in his game, suggests he will be the man to defeat.
Thiem cannot be ignored for his superb performances in the group stage, but the Greek has to be the one to win it after his stellar displays at the Finals this year.
