Murray goes through to quarter-finals

Andy Murray took just 49 minutes to move into the quarter-finals of the Australian Open today after Kazakhstan’s Mikhail Kukushkin was forced to retire through injury after losing the opening two sets.

Kukushkin beat Gael Monfils in five gruelling sets in the previous round and those exertions seemed to hinder him from the start, with Murray leading 6-1 6-1 1-0 before Kukushkin pulled out with a left hip flexor problem.
