FRANKFURT, April 11 (Reuters) - A cool finish from Ioannis Amanatidis sent Eintracht Frankfurt through to the final of the German Cup with a 1-0 home win over Arminia Bielefeld on Tuesday.
The Greece international took a pass from Stefan Lexa in the 16th minute and rounded the keeper for the only goal in the one-off tie at the Waldstadion.
Eintracht will face either holders Bayern Munich or third division St Pauli in the final on April 29 at the Olympiastadion in Berlin.
Eintracht slipped closer to the relegation zone after a 1-0 defeat by Bielefeld on Saturday.
They quickly shrugged off those league worries on Tuesday, attacking with relish and taking a deserved lead with the fine run and shot from Amanatidis.
Fatmir Vata almost equalised a minute later when he smacked the corner of post and crossbar with a long-range effort but the home side were soon back in charge.
Amanatidis sent Markus Weissenberger clear down the left early in the second half for what should have been 2-0.
Bielefeld had one good chance after the break when Isaac Boakye muscled his way into space on the right of the area in the 69th minute only to see the keeper save with his feet.
Arminia Bielefeld also lost in the semi-finals last season to eventual winners Bayern.
Felix Magath's side, looking to complete a second successive domestic double, are away to St Pauli in the second semi-final on Wednesday.
