Bayern Munich extended their lead at the summit of Die Bundesliga to six points.
Bayern Munich extended their lead at the summit of Die Bundesliga to six points but were made to work hard for the three points in a 2-1 win over Mainz.
Claudio Pizarro handed the champions and hosts a 28th minute lead only for the visitors to restore parity within seven minutes through Benjamin Auer.
Pizarro struck ten minutes after half time to claim the win - Bayern's 12th from their opening 14 fixtures.
A late strike from David Jarolim ensured that Hamburg continued their pursuit of Bayern by claiming a 1-0 win at Bayer Leverkusen.
Hamburg leapfrogged over Werder Bremen and into second after Schalke beat the visitors 2-1 at AufSchalke Arena.
German international striker Kevin Kuranyi gave the home the side the best possible start with a goal on just two minutes.
Nelson Valdez restored parity for Bremen ten minutes after the interval only for Kuranyi to complete his brace on 64. Torsten Frings was dismissed for a second bookable offence late on for the vanquished visitors.
Kaiserslautern's wretched start to the season showed no signs of abating after they were trounced 5-1 at mid-table Hannover.
A first half brace from former Bayern and Manchester City defender Michael Tarnat left the visitors with a mountain to climb as early as the 26th minute.
Thomas Brdaric made Kaiserslautern's mission even more improbable although Boubacar Sanogo did register a 69th minute response to make the score 3-1.
Brdaric then added his second and Hannover's fourth in the 73rd minute before Vahid Hashemian completed the rout five minutes from time.
Borussia Dortmund moved into the top six with a 2-1 win at Nurnberg.
David Odonkor and Nuri Sahin gave the visitors a 2-0 half time lead before Stefan Kiessling earned an 87th minute consolation for Hans Meyer's side.
In the day's other clash Wolfsburg and Arminia Bielefeld drew 0-0 at Volkswagen Arena while the match between MSV Duisberg and Cologne was postponed due to a frozen pitch.
