Four-time champion Novak Djokovic overcame a first-set wobble against unheralded Corentin Moutet, beating the 97th-ranked Frenchman 7-6 (7-2), 6-4 to reach the third round of the Paris Masters on Wednesday.

The top-ranked Djokovic lost his serve in game seven and needed to save two set points in order to hold the ninth game at 5-3 down. The 16-time Grand Slam winner broke back for 5-5 against his 20-year-old opponent, who has never won a title while Djokovic chases a 77th.

U.S. Open champion Rafael Nadal, who is battling with his old rival Djokovic for the year-end No. 1 ranking, won 7-5, 6-4 against unseeded Frenchman Adrian Mannarino. The second-seeded Spaniard next faces 16th-seeded Stan Wawrinka, with an 18-3 lead in their career meetings.
