Holders Bayern Munich crushed Hanover 96 4-1 with two goals from Thomas Mueller to reach the German Cup round of 16 On Wednesday.
Bayern looked to be cruising to an easy victory when Mueller and Claudio Pizarro struck in the first half with the hosts in complete control.
Mueller, however, made sure of Bayern's spot in the next round when he connected with a Xherdan Shaqiri free kick to grab his second goal in the 64th.
Substitute Franck Ribery added another when keeper Ron-Robert Zieler failed to hold a powerful Mueller drive 12 minutes from time.
"We took our foot off the gas after the 2-0 and Hanover immediately got better," Mueller told reporters.
"We were not pressing aggressively enough and we sudden were faced with a problem. You always have to keep putting in a lot to be successful."
Schalke 04 were far less convincing but managed to recover from their 4-0 demolition by Bayern Munich last week to beat third-tier Darmstadt 98 3-1.
Benedikt Hoewedes rose high to head the visitors back into the lead on the hour after Jefferson Farfan's 35th-minute lead was cancelled out by Hanno Behrens' header a minute later. Max Meyer sealed the win in the 86th.
Coach Jens Keller also brought on former Germany international and Schalke reserve player Gerald Asamoah in the closing stages for his final appearance for a club he also played for from 1999 to 2010.
Second tier Kaiserslautern came from a goal down to dump out Bundesliga Hertha Berlin 3-1.
Unmarked Peter Niemeyer controlled and drilled in to put Hertha ahead in the 25th minute but the hosts bounced back in the second half, scoring three times through Mohamadou Idrissou, Karim Matmour and Canadian Olivier Occean.
Last season's runners-up VfB Stuttgart also bowed out with a 2-1 defeat at Freiburg.
Eintracht Frankfurt comfortably beat second division VfL Bochum 2-0 with Japanese Takashi Inui scoring one goal and setting up another in the space of two minutes.
