Chief Editor Ubaldo Scanagatta summarizes the last Round Robin day of the tournament. Rafael Nadal kept his hope alive defeating Stefano Tsitsipas, who had already qualified; however Sasha Zverev took charge of his own destiny and moved to the semifinals by beating Daniil Medvedev during the evening match.

Chief Editor Ubaldo Scanagatta relives the extraordinary performance by Roger Federer, who took his revenge over Novak Djokovic after the heart-crushing defeat at Wimbledon. Djokovic will now be unable to return to the top of the ATP Ranking before the end of the year. In the first match, Matteo Berrettini defeated in straight sets Dominic Thiem, who was already certain of a spot in Saturday’s semifinals. It is the first match ever won by an Italian player at the ATP Finals (in nine attempts).
