Greek teenager, Stefanos Tsitsipas, secured the biggest win of his career when he sent Wimbledon champion, Novak Djokovic, packing in the third round of the Rogers Cup. Tsitsipas stunned 6-3 6-7(5) 6-3 win on Thursday. A confident Tsitsipas sent a blistering forehand to the back corner while the ninth-seeded Serbian was heading the other way. It was his first match point to secure the win before looking at his box in disbelief. “It’s a dream of any kid out there in this world, any kid that’s playing tennis, to beat these kinds of players. “So, I can call it the best moment of my life,’’ a shocked Tsitsipas said in an on-court interview. “I never expected to beat such a top-ranked player and such a high-respected player like Novak.’’ Tsitsipas, who turns 20 on Sunday, relied on his serve and forehand combination to get by Djokovic. The Serbian was competing in his first tournament since collecting his 13th grand slam title at the All England Club last month. The Greek teen made some crucial errors near the end of the second set that allowed Djokovic, a four-time winner of the tournament, to set up a decider. However, Tsitsipas did well to break Djokovic for a 2-0 lead in the third set and never looked back. For the resident of Athens, the win is the latest in a breakthrough campaign during which he has reached the quarter-finals or better at seven ATP main tour events. The Greek arrived in Toronto fresh off a run to the semi-finals in Washington, where he lost to German world number three, Alexander Zverev. Tsitsipas, who beat Austrian seventh seed, Dominic Thiem, in the second round here, will next face either second seed, Zverev or Russian qualifier, Daniil Medvedev.
