Bottom Bundesliga club Darmstadt recorded a first league win in almost four months with a shock 2-1 victory over high-flying Borussia Dortmund on Saturday.
Newly acquired U.S. international Terrence Boyd and Antonio-Mirko Colak provided the goals as Torsten Frings' side tasted success for the first time since Oct. 22.
Dortmund had only goalkeeper Roman Burki to thank for preventing a heavier defeat.
Burki saved from Boyd before Jan Rosenthal hit the post and he then stopped another effort from Marcel Heller, before Boyd fired the home side into a deserved 21st-minute lead when Heller pulled the ball past four stranded Dortmund defenders.
Marco Reus struck the crossbar with a free kick in response before Raphael Guerreiro equalised with a fine strike before the break.
Substitute Colak restored Darmstadt's lead with more than 20 minutes remaining and the home side might have scored more -- Burki pushed Colak's strike onto the crossbar and saved from Rosenthal on the rebound.
