Hamburg kept alive their Bundesliga title challenge with victory at home over Energie Cottbus today.
Ivica Olic scored Hamburg's opener in the 32nd minute with Piotr Trochowski adding another seven minutes later.
The victory ended a two-match losing streak for the hosts, who move level on 45 points with Bayern Munich and Wolfsburg - four behind leaders Hertha Berlin.
Cottbus lost their third successive game and remain 17th in the standings with 20 points, two from safety.
Hamburg were the more attacking team early on with Jose Paolo Guerrero's 15-yard strike going just wide after six minutes.
In the 28th minute, Cottbus defender Ivan Radeljic was seen to tug Albert Streit's shirt in the area but the referee did not point to the spot.
Hamburg finally went ahead after 32 minutes when Cottbus lost the ball on the right of the pitch.
Mickael Taveras pounced on the mistake by Radeljic and sent a cross into the area where a charging Olic beat Cottbus goalkeeper Gerhard Tremmel with a header into the left corner.
The hosts doubled the lead just seven minutes later with a free-kick from 22 yards by Trochowski.
Tremmel was poised for a cross into the area from the Germany international, but Trochowski instead smashed the ball into the top right corner.
Hamburg almost added another three minutes after the break but Ivica Iliev cleared on his own goalline.
Cottbus tried to pull a goal back and in the 56th minute Emil Jula sent Dimitar Rangelov into the area, but the Bulgarian striker's shot went just wide of the far post.
Hamburg were happy to sit back in defence and Cottbus could not find a way through, with Iliev's long distance shot the best they could muster.
