The Canadian, a semi-finalist at the year's opening grand slam in 2016, was stunned by Lukas Lacko 6-7 (5-7) 7-5 6-4 7-6 (7-4).

World number 23 Raonic underwent wrist surgery last year, but he has been a regular contender at Melbourne Park.
However, his loss to Lacko marked the first time he has suffered a first-round Australian Open loss.
It was also his earliest grand slam exit since the 2011 French Open.
