Bremen reach German Cup final
Germany international Marko Marin slotted home on 30 minutes and Peruvian Claudio Pizarro sealed the win with a curled low drive six minutes from time.
Bremen will defend their title on May 15 in Berlin against the winner of the other semi-final between Schalke 04 and Bayern Munich, who meet on Wednesday.
Bremen dominated possession from the start but had to wait until the 30th minute to break the Augsburg resistance when Marin sliced through with a one-two pass off playmaker Mesut Ozil and wrong-footed keeper Simon Jentzsch with a well-placed shot.
Bremen fell back after the goal as Augsburg pressed the hosts and they hit the woodwork when Michael Thurk beat keeper Tim Wiese but saw the ball hit the far post and agonisingly roll across the goal-mouth before being cleared.
Thurk, the second division's top scorer with 21 goals in 27 matches, kept up the pressure after the break but Pizarro, picked out by a Torsten Frings free-kick, struck with a low drive in the 84th minute to send Bremen through.
