Ankle injury threatens to overshadow end of comfortable Murray win

Updated: 

Andy Murray booked his place in the Australian Open third round but his victory over Andrey Rublev was not without incident as the world number one appeared to injure his ankle.

The top seed had little trouble in seeing off his teenage opponent 6-3 6-0 6-2, but his third-round encounter with Sam Querrey could be more tricky, especially after the Scot rolled his right ankle in game three of the final set.

Murray, a five-time losing finalist at Melbourne Park, looked calm and assured for the majority of this encounter against his Russian opponent, ranked 152nd in the world.

The 19-year-old Rublev showed promise, but ultimately the experience and rock-solid defence of Murray proved unshakeable.
