Hamburg coach gets off to great start
Pierre Michel Lasogga set up Petr Jiracek's 42nd-minute headed opener and scored in the 58th. Hakan Calhanoglu completed the win with an improbable 45-meter (yard) free kick in injury time.
Slomka took over last Monday from Bert van Marwijk, who was fired after the side lost its previous eight games in all competitions.
''The result is a bit flattering,'' Slomka said. ''But we did well in defense over long periods and the team can be proud of these points. Today was one of 13 (remaining) games and we'll never stop working.''
Bas Dost got the home side off the mark in the 13th, before Leverkusen winger Sidney Sam equalized just before the break.
Luiz Gustavo restored Wolfsburg's lead in the 58th and Ricardo Rodriguez made it 3-1 on the rebound in the 73rd after Bernd Leno saved his initial penalty attempt.
It was Leverkusen's seventh defeat in nine games across all competitions, and means Bayern Munich can stretch its lead to 19 points with a win at Hannover on Sunday.
The home side started well in Hamburg, restricting opportunities for Dortmund, which visits Zenit St. Petersburg in the Champions League on Tuesday.
Jiracek beat two defenders to meet Lasogga's cross at the far post, after the Hamburg striker did well to keep the ball in play.
Calhanoglu won the ball from Nuri Sahin and Firat Arslan sent Lasogga through to finish with aplomb past Roman Weidenfeller.
Rene Adler made a host of good saves as Hamburg kept a clean sheet for the first time after 14 games. His side had conceded at least three in its previous seven games including the 5-0 German Cup defeat to Bayern Munich.
''It's so nice to be rewarded like this at the end of the week,'' said Adler, who was criticized after last week's 4-2 defeat to Braunschweig.
Calhanoglu completed a memorable afternoon when he belted his free kick from near the center circle over Weidenfeller. The Dortmund goalkeeper retreated but was unable to keep the ball out as it dipped in.
''A win at home is a great feeling, one that I've missed,'' Hamburg midfielder Milan Badelj said. ''But it's just a win. We're still in a difficult situation.''
Freiburg was left fuming after Christian Guenter was booked for diving in the 86th when it looked like he should have been awarded a penalty. Augsburg was leading 3-2 at the time.
The home side's protests were ignored and Andre Hahn completed the scoring in injury time, leaving Freiburg one point below Hamburg.
''I'm not saying anything about the referee's decision,'' Freiburg coach Christian Streich said.
Nuremberg was left with an uphill battle when defender Per Nilsson was sent off in the 32nd and Domi Kumbela scored for Braunschweig two minutes later.
It could have been worse when Raphael Schaefer conceded a penalty on Kumbela, but the Nuremberg goalkeeper atoned by saving Kumbela's weak effort.
Nuremberg turned the game around with two goals in two minutes, Hiroshi Kiyotake scoring after a well-worked move 10 seconds after the restart and Tomas Pekhart adding another with the visitors still in shock.
They were given a lifeline when Javier Pinola conceded another penalty in the 63rd, but Schaefer also saved Ermin Bicakcic's effort from the spot.
Braunschweig `keeper Marjan Petkovic saved Kiyotake's penalty five minutes later.
''We remain optimistic,'' said Braunschweig coach Torsten Lieberknecht, whose side remains bottom. ''Nuremberg have already shown how to work your way out.''
Hertha defender Levan Kobiashvili scored in the fifth in Stuttgart, making the 36-year-old the club's oldest goal scorer in the Bundesliga, only for Arthur Boka to equalize with a rocket from outside the penalty area before the break.
Wagner scored with a header in the 87th, and was then sent off in injury time with two yellow cards in as many minutes.
''We're incredibly disappointed,'' Stuttgart coach Thomas Schneider said. ''The team showed it was alive. They threw everything into it.''
