Novak Djokovic

Djokovic beat 10th seed Gael Monfils 6-3 6-2 3-6 6-2 in New York, with the Frenchman adopting unusual tactics to try and counter the world number one. Defending champion Novak Djokovic will take on third seed Stan Wawrinka in the US Open final after both men won semi-finals in punishing conditions.

Djokovic, 29, had treatment on both shoulders during the first semi-final, while Monfils could barely move at times as conditions took their toll. Stifling humidity was still a factor as Wawrinka beat Japan’s sixth seed Kei Nishikori 4-6 7-5 6-4 6-2.

Djokovic had spent only six hours and 24 minutes on court in reaching the semi-finals, thanks in part to one walkover and two retirements, and he was within sight of another swift contest against Monfils.

Monfils, 30, was back in the match but he was hardly fizzing with energy, calling for the trainer early in the fourth set, bending double at every opportunity and even drinking a Coca-Cola at one changeover. Monfils has now lost all 13 matches against Djokovic.
