OPEN AND SHUT: Murray coasts to win
Andy Murray faces a tough test in round four of the Australian Open after winning through to the last 16 with a straight-sets victory over Florent Serra.
The British No 1 and tournament fifth seed has not dropped a set so far in his three matches, and yesterday beat Frenchman Serra 7-5 6-1 6-4.
His next opponent will be big-serving American John Isner, who caused an upset by knocking out 12th seed Gael Monfils in four sets. Isner won the Heineken Open in Auckland last week.
