BERLIN (AP) " Bayern Munich enjoyed another big Bundesliga win as it pursues an unprecedented fifth straight title while Borussia Dortmund was held at Schalke to 1-1 in the Ruhr derby on Saturday.
Robert Lewandowski scored a hat trick and set up another two goals for Bayern to rout Augsburg 6-0 at home, maintaining its 13-point lead over Leipzig with eight games remaining.
"Lewandowski did what he normally does," Bayern coach Carlo Ancelotti said.
Bayern, which has lost only once in 26 league games, didn't have to work too hard for its 20th win. Augsburg opted to rest several players for its relegation fight with Ingolstadt on Wednesday.
"A defeat against Bayern won't throw us off course," said Augsburg coach Manuel Baum, whose side dropped to the relegation playoff spot.
Minutes after Dortmund striker Pierre-Emerick Aubameyang claimed his league-leading 24th goal in Gelsenkirchen, Lewandowski claimed his 23rd, firing inside the left post after holding off a defender.
The striker then set up Thiago Alcantara with his heel before completing his hat trick and matching Aubameyang's tally with a header.
A long ball from Jerome Boateng set up Thomas Mueller for his second of the second, though the Germany forward went straight off for treatment following a bad challenge from Christoph Janker, who was booked.
SCHALKE 1, BORUSSIA DORTMUND 1
The 150th competitive Ruhr derby ended badly for Schalke, denied what looked a clear penalty in injury time after Marc Bartra stopped the ball with his arm. Schalke coach Markus Weinzierl was sent to the stands for his protests.
"We needed a bit of luck that the referee did not blow for handball at the end, not that he has to, but he can," Dortmund coach Thomas Tuchel acknowledged.
Dortmund had the better of a hard-fought first half with more shots on goal before Aubameyang finally broke the deadlock early in the second half.
Ousmane Dembele timed his pass perfectly for Shinji Kagawa to beat the offside trap and the midfielder unselfishly laid the ball off for Aubameyang's simple finish. The striker pulled on a mask " as he has done before " and prompted a furious reaction from Schalke fans with his celebrations.
Thilo Kehrer got them smiling again with the equalizer in the 77th, firing inside the left post for his first Bundesliga goal after Leon Goretzka dragged the ball back.
