Bayern Munich moved four points clear at the top of the Bundesliga with a 1-0 win over visiting Werder Bremen on Saturday.
Centre-back Niklas Suele struck the 75th-minute winner with a deflected shot from 20 metres.
Borussia Dortmund are at Freiburg on Sunday hoping to restore the gasp to one point, with then four matches remaining of the season.
Bayern's winner came after Bremen had been reduced to 10 men shortly before the hour when Milo Veljkovic was shown a second yellow card for using an elbow against Suele.
Bremen keeper Jiri Pavlenka had kept his side level with a series of saves from Robert Lewandowski and Serge Gnabry, tipping one shot onto the post. Lewandowski also came close to a second with a shot onto the top of the bar.
Bremen stay seventh but will have the chance to avenge the defeat on their own ground when they meet Bayern again on Wednesday in the semi-finals of the German Cup.
Augsburg thrashed VfB Stuttgart 6-0 in a home debut for coach Martin Schmidt, with a brace each from Philipp Max and Marco Richter and goals from Rani Khedira and Andre Hahn.
Augsburg, who won 3-1 at Eintracht Frankfurt last week in Schmidt's first game in charge, pull clear of the relegation zone, advancing to 31 points.
They are 10 ahead of Stuttgart, who have suffered their worst-ever defeat and stay firmly lodged in the relegation play-off place in mounting pressure on coach Markus Weinzierl.
Bayer Leverkusen climbed to sixth in the battle for a European qualification spot by beating relegation-threatened Nuremberg 2-0, courtesy of second-half goals from Lucas Alario and Kevin Volland.
Nuremberg remain three points adrift of Stuttgart, with tailenders Hanover four points further back, while Leverkusen could be overtaken later by Hoffenheim.
Mainz defeated fellow midtable side Fortuna Duesseldorf 3-1, Jean-Philippe Mateta bagging two goals.
In later games, Borussia Moenchenglabach host third-placed RB Leipzig, while Schalke greet Hoffenheim.
