DUBAI (Reuters) - Novak Djokovic extended his winning streak to 18 matches to claim a fourth Dubai Championships in five years on Saturday, underlining his status as the world's best player after beating Tomas Berdych 7-5 6-3 in the final.
The Serb was ruthless in coming back from a break down in the first set, converting two break points out of three, while Berdych only managed to make one of his four count.
