Dortmund, Germany (SportsNetwork.com) - Robert Lewandowski's first-half strike held up as the winner on Saturday as Bundesliga leaders Bayern Munich claimed a 1-0 victory over Borussia Dortmund at Signal Iduna Park.
Bayern has been flying all season, leading the league from the outset, but suffered a 2-0 loss to Borussia Monchengladbach on March 22 prior to the international break.
Pep Guardiola's men entered Saturday's match looking for three points to get the positive momentum flowing again, but it was a chippy affair early on as referee Knut Kircher handed out three yellow cards in the opening 30 minutes.
The only goal of the contest came in the 36th minute as Lewandowski found himself with some space in the penalty area and nodded one past Dortmund goalkeeper Roman Weidenfeller for his 14th goal of the campaign.
Dortmund send numbers forward in front of the home fans looking for the equalizer, but it never came and Bayern escaped with all three points to push its lead atop the table to 10 points over second-place Wolfsburg.
Dortmund, meanwhile, remains in 10th place on 33 points from 27 matches played.
Also in the Bundesliga on Saturday, Bayer Leverkusen claimed a comfortable 4-0 win over Hamburg thanks to braces from Gonzalo Castro and Stefan Kiessling, while Hannover rallied from a 2-0 deficit to claim a point with a 2-2 draw against Eintracht.

Herrmann completed his double in the 51st minute to wrap up all three points and keep Monchengladbach in third place with 50 points.
