Schalke begin defence with 11-goal rout
Schalke 04 began their defence of the German Cup with an 11-1 rout of seventh tier Teningen whose players were banned from half-time shirt swapping by their coach.
Freiburg became the fourth Bundesliga team to succumb to lower league opponents when they were beaten 3-2 at Unterhaching with Mijo Tunjic scoring two penalties including, an 87th minute winner for the third division side.
Hoffenheim had a narrow escape as they came from behind for a 3-1 extra-time win at sixth-tier Germania Windeck and Mainz 05 also needed extra-time for a 2-1 win at fifth tier Zweibruecken.
The German federation tries to maximise the chances of upsets by forcing Bundesliga teams to play away to lower league sides in one-leg first round ties.
Schalke had no such trouble as they raced to a 3-0 lead after only 13 minutes although Florian Kirstein headed one back for Teningen's amateurs, whose coach Claus Kraskovic warned he would substitute any starry-eyed player who tried to swap shirts with their illustrious opponents at half-time.
Hanover 96, who suffered first round defeats in the previous two seasons, made no mistake this time as they routed Wismar 6-0 while Hertha Berlin won 4-0 at Meuselwitz and Cologne 3-0 at Wiedenbrueck.
Second division Greuther Fuerth also hit double figures with a 10-0 win at Eimsbuetteler, Sercan Sararer scoring four.
