The Scottish champions conceded a penalty corner in only five minutes and Thilo Stralkowski fired a powerful drag flick into the roof of the net off Mark Fulton’s outstretched stick.
Chris Ruhr then beat two defenders and sent a reverse stick shot past Fulton. Johannes Schmitz scored a third and Ruhr added a fourth just on the interval with a well taken goal.
The Germans found the net again through Schmitz, whose powerful strike seemed to go through Fulton into the roof of the net.
Meanwhile, in a catch-up Arthur McKay Scottish Cup tie, second division leaders Dundee Wanderers finally saw off Dundee University with a late strike by James Weyers from the spot. This result sets up an all-Tayside quarter-final tie with city rivals Grove Menzieshill.
