Novak Djokovic won the Dubai Championships for the fifth time on Saturday, defeating Stefanos Tsitsipas 6-3, 6-4. The world number one remains an undefeated 18-0 this season as he ended an eight-match win streak for his Greek opponent, champion last weekend in Marseille. Djokovic, with three titles including the inaugural ATP Cup with Serbia in 2020, put a winner into the corner on match point. str/mw
