MELBOURNE, Jan 17 (Reuters) - Andy Murray kept his cool in a Melbourne scorcher to reach the third round of the Australian Open with a businesslike 6-2 6-2 6-4 victory over Joao Sousa on Hisense Arena on Thursday.
The British third seed looked intent on keeping his time in the heat and humidity to the absolute minimum, wrapping up victory in just 101 minutes when his Portuguese opponent went long with a return.
Two breaks in the first set, a couple in the second and one more in the third proved enough to set up a meeting with Lithuanian Ricardas Berankis, who earlier stunned German 25th seed Florian Mayer 6-2 6-3 6-1.
Murray, who is chasing a second successive grand slam title after his breakthrough triumph at the U.S. Open, has reached the semi-finals at Melbourne Park for the last three years. (Reporting by Nick Mulvenney, editing by Peter Rutherford)
