Bayern Munich ground out a hard-fought 2-0 victory over bottom side Eintracht Braunschweig on Saturday to end the champions' three-game winless streak in the Bundesliga. Claudio Pizarro broke the deadlock in the 79th minute, when Mario Goetze sent the Peruvian through, and Mario Mandzukic secured the win with three minutes remaining as the home side pushed for an equalizer. Bayern coach Pep Guardiola had started his strongest available side to fine tune for Wednesdays' Champions League semifinal first leg at Real Madrid. Second-place Borussia Dortmund defeated visiting Mainz 4-2, and Freiburg took a giant step in its fight against relegation by beating Borussia Moenchengladbach by the same score. Werder Bremen came from behind to beat Hoffenheim 3-1 and Augsburg drew 0-0 with Hertha Berlin. Hamburger SV was hosting Wolfsburg later.
