BERLIN, April 29 (Reuters) - Bayern Munich beat Eintracht Frankfurt 1-0 to win the German Cup on Saturday for the 13th time and move a step closer to a second successive double.
Peruvian striker Claudio Pizarro muscled his way between two defenders to butt in a Ze Roberto corner in the 59th minute of an uninspiring match at a rain-soaked Olympiastadion.
Frankfurt struggled to make chances on the heavy pitch and Bayern looked comfortable before a last surge forward almost brought the underdogs reward.
Ioannis Amanatidis, suddenly finding himself with space in the centre of the penalty area with three minutes to go, swept goalwards but Oliver Kahn pulled off a finger-tip reflex save to secure the Cup for Bayern.
Felix Magath's side can now turn their attention to the last three games of the Bundesliga season.
They have a five-point lead and could wrap up their 20th title as early as Wednesday night.
Landing back-to-back doubles would be a unique feat in Germany's Bundesliga era, dating back to 1963.
Frankfurt, in 13th place, will now concentrate on avoiding relegation, with a key game against Kaiserslautern coming up on Wednesday.
Bayern played just as they have done all season, with a bit too much quality for their more lowly domestic rivals but without ever really looking impressive.
Michael Ballack and Pizarro combined to set Roy Makaay away down the left in the third minute, with the Dutchman forcing a save from Oka Nikolov with a snap shot.
Bayern continued to focus on that wing whenever they managed an attack, Philipp Lahm proving a menace to the Frankfurt defence.
The favourites were generally content to keep the ball in midfield, however, waiting for the gaps to open up.
Sadly, in terms of a spectacle, there were not many of them.
Rain had been pouring down for much of the day and the decision to play the women's Cup final on the same pitch a few hours before ensured the conditions were not any easier.
Frankfurt sat back but did threaten a couple of times in the first half when Benjamin Huggel broke free of his marker in the area. Each time he opted to cross rather than shoot and Bayern were able to clear.
In the last minute before the break, Alex Meyer collected the ball in space on the right of the Bayern area but also failed to trouble Kahn with a shot.
Predictably enough, it was a set-piece that broke the deadlock, with Pizarro proving too strong for two defenders manning the far post.
Five minutes later Frankfurt thought they had a penalty, or at least a free kick on the edge of the box, as Benjamin Koehler raced through on goal and went down under Willy Sagnol's challenge.
The referee shrugged off the claims and there were no further chances for Frankfurt before that last effort from Amanatidis brought them desperately close to an equaliser.
