Scottish star Andy Murray is through to the second round of the Australian Open after his first opponent retired midway through the second set on Tuesday with a back injury.
The fourth-seeded Murray was leading Andrei Pavel 6-2 3-1 when the Romanian called it quits.
Murray, one of the early title favourites following a series of wins over Roger Federer and Rafael Nadal already this season, will next play either Russian Teimuraz Gabashvili or Spain's Marcel Granollers on Thursday for a place in the last 32.
