Murray hurries into Australian Open fourth round

The 22-year-old Scot's progress to the fourth round looked like it would be an easy one when he raced to a 3-0 lead in the first set against the Frenchman, who had to play five sets in both of the previous rounds.

Though to Murray's frustration Serra leveled it at 3-3 then 5-5 but the world number four prevailed and increased the pressure on his crafty opponent's serve, loping away with the second and third sets.

He now plays either big serving American John Isner or 12th seeded Frenchman Gael Monfils in the next round.
