Four-time finalist Andy Murray has set up a showdown with home hope Sam Groth after steaming through his first-round match at the Australian Open.
The second-seeded Murray blasted past young German Alexander Zverev 6-1 6-2 6-3 to join in-form Canadian Milos Raonic as an early day-two winner at Melbourne Park.
Raonic, who opened the season with victory over Roger Federer in the Brisbane final, beat Frenchman Lucas Pouille 6-1 6-4 6-4, while Groth advanced with a 7-6 (8-6) 6-4 3-6 6-3 win over Adrian Mannarino.
