PARIS — Karen Khachanov upset a tired-looking Novak Djokovic 7-5, 6-4 to win the Paris Masters title and deprive Djokovic the chance on Sunday of matching Rafael Nadal's record of 33 Masters titles.
Djokovic, a record four-time champion at the indoor event, looked out of energy after an epic three-hour semifinal win against Roger Federer on Saturday.
Although Djokovic broke in the fourth game to move 3-1 up and then led 30-0 on serve, the unseeded Khachanov broke him straight back and the momentum abruptly shifted away from Djokovic.
The Serb seemed agitated at times and twice turned to his box to remonstrate about an unspecified issue during the first set.
