Just a year after conquering the Next Gen ATP Finals, the 21-year-old Stefanos Tsitsipas is through to the ATP Finals title match, beating the six-time champion Roger Federer 6-3, 6-4 in an hour and 35 minutes. Making a debut in London, Stefanos is through to the ninth and most notable final in a career, delivering another rock-solid performance and earning the third triumph at the O2 Arena this week.
It was their fourth clash and the second win for the Greek, saving 11 out of 12 break chances (similar to their match from Melbourne) and clinching three breaks to move over the top in straight sets. The youngster had the upper hand in the pivotal points, keeping his focus on a high level and taking advantage of too many forehand errors from Federer who was nowhere near his level from the clash against Novak Djokovic two days ago.
Stefanos won three points more in the tight opening set, having the upper hand in the shortest rallies and fending off all six break point to mount the pressure on Roger! The Greek repelled a break chance in the very first game and stole Roger's serve with a forehand winner in game two after two missed smashes from the Swiss, something we can see once in ten years.
Serving at 4-2, the young Greek fended off three break opportunities to stay in front, having a chance to close the set on his serve at 5-3. That ninth game proved to be the longest one of the match, with eight deuces and two break points for Federer who had the opportunity to prolong the set.
Stefanos erased them and converted the seventh set point with a service winner for a 6-3 after 46 minutes. Carried by this momentum, Tsitsipas broke at love in the third game of the second set after another forehand error from Roger who finally seized the fourth break point in the next game to level the score at 2-2 following a loose forehand from the youngster.
The Swiss wasted two game points a few minutes later and suffered a break after a forehand winner from Stefanos who fended off two break points in game ten to seal the deal in straight sets after an ace that propelled him into the final.
