During the second set it was clear Monfils was struggling to cope with the heat and the Frenchman was doubled up, leaning on his racket, after some especially long rallies. After Djokovic levelled the match it looked as though Monfils might throw in the towel during a one-sided third set but the 31-year-old offered some late resistance in the fourth. Fourteenth seed Djokovic broke in the eighth game though but failed to convert his first match point and then faced a break point after losing a rally that left him gasping for air. Monfils saved two more match points, the second with a superb crosscourt forehand, but Djokovic converted at the fourth attempt with a simple volley.Novak Djokovic sees off Gael Monfils in four sets.
