London : In the World Tour Finals released in London between Corona, World No.1 Serbia’s Novak Djokovic defeated Alexander Zverev of Germany 6-3, 7-6. With this, Zverev missed out on Roger Federer’s record of winning 6 tournaments in one season. Djokovic was defeated by world number-4 Daniel Medvedev in the second match of the round robin. They will now face Dominic Thiem in the semi-finals. In another semi-final, Rafael Nadal and Denil Medvedev will clash. After the victory, Djokovic said that I am happy to win the match. He had good chances at break point in the first set. But I played in my favor by playing better in this crucial time. I succeeded in playing the right shot at the right time against Daniels. They are good players. His shots coming at a speed of 140 meters per hour are not easy to play. But I played his shots better.
