Novak Djokovic’s streak of 19 consecutive wins was ended as the home crowd favorite, Jannik Sinner, claimed a fantastic victory of 7-5, 6-7 (5), 7-6 (2) over the partisan ATP Finals crowd in Turin. The match lasted over three hours and both players fought fiercely, but it was Sinner, ranked No.4 in the world, who ultimately took advantage in the tie-break of the final set to break through Djokovic’s defenses. At just 14 years younger than Djokovic, Sinner secured his first ever win against the 24-time grand slam champion with a powerful smash.
