Australian fifth seed Bernard Tomic made a winning start in the BMW Open in Munich with a comfortable 6-4 6-3 victory over Belgian veteran Olivier Rochus on Sunday.

The 19-year-old Queenslander needed just 68 minutes to book his place in the second round, fighting back from being broken himself in the first set and seizing his solitary break point opportunity in the next.

In the only other first round action on the opening day, Colombia’s Santiago Giraldo took 76 minutes to record a convincing 6-4 6-3 win over Belgium’s world number 67 Steve Darcis.
