US Open: Andy Murray fights back to defeat Emilio Nava in second round

• Murray rallies from losing first set to win 5-7, 6-3, 6-1, 6-0
• No 13 seed Matteo Berrettini awaits in third round

Andy Murray arrived at Arthur Ashe Stadiumconscious of the fact that this was a match he could not afford to lose.

Over the past year, Murray has recorded a number of strong wins against highly ranked players, but he has often been unable to use them as catalysts for deeper runs or greater consistency. After a great straight sets firstround win against Francisco Cerundolo, the 24th seed, it was essential that he consolidated his form appropriately in a match he was heavily favoured to win.
