Vedad Ibisevic and Chinedu Obasi each bagged a brace as Hoffenheim ended a seven-game winless run with a thumping 5-1 victory over Europa League semi-finalists Hamburg.
Ibisevic wasted little time getting off the mark, scoring in the second and 11th minutes as the hosts jumped out into an early 2-0 lead. Obasi made it 3-0 after 31 minutes before Robert Tesche trimmed the deficit after 65 minutes. Obasi finished off the game with his second in the 73rd minute before Sejad Salihovic made it five 13 minutes from time. Hamburg's Tolgay Arslan was sent off for violent conduct in the final minute.
The win moves Hoffenheim onto 38 points in 11th place, while Hamburg, who travel to Fulham for the return leg of their Europa League semi on Thursday, stay seventh on 48 points.
Freiburg shock the champions
Cedrick Makiadi's first-half goal proved enough as Freiburg boosted their chances of staving off relegation with a surprise victory over reigning Bundesliga champions Wolfsburg.
Makiadi scored the only goal of the game in the 38th minute to help Freiburg continue their impressive run at home, where they have collected 10 points in the last four home matches.
And they were able to take advantage of defeats by those around them and jump into 14th place, three points above the drop zone. Wolfsburg remain in eighth place on 46 points and have no hope now of making it into Europe next season.
