World number one Sir Andy Murray has defeated Sam Querrey in straight sets to advance through to the fourth round of the Australian Open.

The Scot - the new favourite after Novak Djokovic's shock exit on Thursday - wrapped up a 6-4 6-2 6-4 victory in just one hour 59 minutes at the Hisense Arena in Melbourne.

World number 31 Querrey never really troubled Murray, his best chance of turning the narrative coming with a break point in the eighth game of the first set, but his opponent was able to save the game before turning the tables with a successful break in the next game.

Murray went on to win seven games in a row as he took the second set with ease, with an exchange of breaks early in the third followed by a decisive break to secure the contest for the favourite.

A fourth-round tie now against Germany's Mischa Zverev now awaits the title-chasing Murray, who has previously finished runner-up five times.
