WATCH: Andy Murray reaches Australian Open last 16 despite ankle issues

Murray will now face Germany's world number 50 Mischa Zverev.

Andy Murray did what Novak Djokovic could not by beating Sam Querrey with ease to reach the fourth round of the Australian Open.

Djokovic not only lost to Querrey at Wimbledon last year but crashed out in round two here to wildcard Denis Istomin, leaving Murray in pole position to clinch his first Melbourne title.
