Augsburg managed to equalise three times before Gio Reyna's 78th minute looping shot gave the hosts victory in their season restart following a two-month break.
Dortmund struck after 29 minutes with Jude Bellingham weaving a shot through three defenders after creating just the bit of space he needed with a superb move. The Dortmund defender, however, made amends only two minutes later, heading in from a free kick to put them back in front. Dortmund coach Edin Terzic brought on Haller and Jamie Bynoe-Gittens to add more punch to his attack and it paid off with the latter thundering in their third goal from outside the box in the 75th.
