Paris Masters:

Novak Djokovic began his bid for a record-extending fifth Paris Masters title with a 7-5, 6-1 win against Joao Sousa in the second round on Tuesday night, and lent a helping hand to a spectator in the process. Serving for the match at 5-1, Djokovic handed a towel to a man in the crowd who seemed unwell and who wiped his forehead with it. “It seemed he was sweating and he seemed dizzy, so he just needed help,” Djokovic said.

“I just gave him the towel.” Djokovic revealed he also was not feeling very well out on court. “I wasn’t,” he said. “I don’t want to get into details but I think it’s a minor thing.”

The second-ranked Serb set up match point with an ace and sealed victory on his third match point when Sousa returned a second serve long.

The US Open champion won four of the last five tournaments he has entered, including Wimbledon, the US Open and most recently the Shanghai Masters. Djokovic is seeking to reclaim the top ranking from Rafael Nadal at a tournament Nadal has never won. Djokovic next faces Damir Dzumhur.

Fifth-seeded Marin Cilic, the Australian Open runnerup, won his second-round match 6-3, 6-4 against Philipp Kohlschreiber of Germany. Dzumhur upset 14th-seeded Stefanos Tsitsipas 6-3, 6-3, while big-hitting Russian Karen Khachanov also advanced to the third round. He led 6-2, 2-0 against Matthew Ebden when the Australian retired.
