Dortmund travelled to Duisburg in the first round of the German Cup.
Jadon Sancho put Dortmund ahead from the spot after 14 minutes and Jude Bellingham made it two on the half hour. Volkmer was then sent off for the third tier side and that ended any hopes of a fightback. Thorgan Hazard netted a third before the break and then Giovanni Reyna scored from a free-kick early in the second period. Marco Reus' 58th minute goal completed the scoring.
