Tennis player Novak Djokovic has booked his spot in the semi-finals of the Paris Masters after defeating Marin Cilic of Croatia 2 sets to 1.
Djokovic, who's guaranteed a return to the summit of World Tennis next week, struggled on his serve for much of the 1st set, losing it 6-4 to his Croatian opponent.
The Serb however, increased his focus in the 2nd set to level the match with a 6-2 win. In the 3rd set, Djokovic was broken to go 2-1 down, smashing his racket in frustration. But he managed to break Cilic and kept his cool to take the set 6-3, extending his winning streak to 21 matches.
