No career finish line in sight for confident, pain-free Andy Murray

Andy Murray said he is free of pain and has no timeframe for retirement after engineering a turnaround to win his first match of the season on Wednesday. The 35-year-old Scot earned a morale-boosting victory ahead of next week's Australian Open with a typically battling 2-6, 6-3, 10-2 defeat of China's Zhang Zhizhen at the Kooyong Classic.
