Marco Reus scored one goal and set up another as Borussia Dortmund reached the German Cup semifinals with a 3-1 win at Stuttgart that was briefly interrupted by tennis balls on Tuesday, according to Associated Press (AP).
The game was held up briefly to remove a shower of tennis balls that Dortmund fans had thrown onto the pitch. "Great tennis," read a banner in their block. Another banner saying "football must be more affordable" was displayed as part of an apparent protest against ticket prices.
Lukas Rupp equalised in the 21st and Aubameyang restored Dortmund's lead in the 31st. Henrikh Mkhitaryan finally sealed the win on a counterattack in the 89th, according to AP.
"We're still coming off a good run," said Stuttgart coach Juergen Kramny. "To win against Dortmund is never easy. To lose is not abnormal."
"The semifinal opponents are all the same to me," Dortmund chief executive Hans-Joachim Watzke told AP. "Bochum would be nice, but I'd rather concentrate on realistic opponents."
