Australian Open 2013: Andy Murray glad of swift victory

Andy Murray is grateful to take only one hour and 41 minutes to beat Portugal's Joao Sousa in straight sets on a intensely hot day at the Australian Open.

The 2010 and 2011 runner-up in Melbourne says the conditions got tougher towards the end of the match, admitting that to win swiftly was "an added bonus".

Murray will now face Lithuania's world number 110 Ricardas Berankis in the third round.
