Elsewhere, Schalke's miserable end to the year continued despite the dismissal of Huub Stevens as coach on Sunday, with the team losing 2-1 at home to Mainz.
Marco Caligiuri opened the scoring for Mainz in the 30th with a fantastic strike into the right corner.
Klaas-Jan Huntelaar pulled one back from close range with 15 minutes remaining, but Nicolai Mueller scored in the 83rd to ensure the 2011 champion's seven-game run without a win continued.
"Anyone who saw that performance, especially in the second half, could see that the team played well," Schalke's interim coach Jens Keller said.
Mainz coach Thomas Tuchel, who angrily denied newspaper reports linking him with the Schalke position before the game, was sent to the stands for stepping onto the pitch in response to a two-footed lunge from Jermaine Jones on Caligiuri.
"From my perspective it looked like Caligiuri was seriously injured," Tuchel said. "It was just a bit of pushing, here and there, nothing serious."
U.S. international Jones received a yellow for the initial challenge.
Third-division Kickers Offenbach provided an upset by beating Fortuna Duesseldorf 2-0, with Mathias Fetsch and Stefan Vogler scoring for the home side in last 15 minutes.
Freiburg won 1-0 at third-division Karlsruher SC thanks to Jonathan Schmid's goal in the second minute, firing through the goalkeeper's legs.
