Hamburg  - cruised to a 5-2 win over VfL Wolfsburg to book their place in the semi-finals of the German Cup Wednesday while SV Hamburg had a few nervy moments before prevailing 2-1 against SV Wehen.

Five-time winners Bremen raced into an early two-goal lead thanks goals in the first six minutes from midfielders Diego and Mesut Ozil and although Wolfsburg managed to restore parity, a brace from Claudio Pizarro ensured a comfortable win for Thomas Schaaf's side.

Diego showed brilliant technical skill to make it 1-0 after just three minutes and then helped set up the second by cleverly blocking his opponent to allow Ozil to run through to score.

Wolfsburg pulled one back on 10 minutes when Edin Dezko netted from close range and Dezko levelled matters with his sixth goal in two cup games one minute before the break after Bremen defender Per Mertesacker let him head home unchallenged.

However, Diego restored Bremen's two goal lead with a penalty on 55 minutes before Pizarro made the game safe on 71 minutes after being set up by substitute Hugo Almeida.

Pizarro completed the rout with his second of the game a minute from time, although the referee did appear to ignore a raised flag by his assistant.

Bremen have now won their last five cup games against Wolfsburg.

In the other match, Hamburg looked to be cruising against Wehen after a Marko Kopilas own goal on 17 minutes and a Mladen Petric strike on 37 gave Martin Jol's side a
2-0 lead.

However, Sandro Schwarz made it 2-1 in the 85th minute, setting up a tense finish for the Bundesliga side.

Bayer Leverkusen and holders Bayern Munich meet later Wednesday while second division side Mainz 05 booked their place in the semi- finals Tuesday with an upset
1-0 victory over Schalke 04.

The semi-final draw takes place on Saturday. dpa
