Could have done better on both of Rudnevs' strikes, especially on the second when he allowed the ball to escape through his legs.
A strong, solid performance from the centre-back, especially in the air, but was not comfortable dealing with HSV's fluid counters.
Failed to impress in the centre of defence, given a torrid time by Rudnevs and nowhere to be seen when the striker added his second to end the game as a contest.
Struggled to keep hold of Aogo, and his slack marking played a part in HSV's equaliser.
Badly caught out by Son as the Korean breezed past him on the way to handing Hamburg the lead.
Given a tough task keeping tabs on the in-form Van der Vaart, and on more than one occasion let the midfielder slip away.
Forced to play deep in his own half for large spells of the game, nullifying his quality as an explosive threat down the flank.
A strangely muted performance from the talented winger, who was given little space to shine and his contribution was limited to sporadic involvement.
Great expectations surrounded BVB's prodigal son on his first start, but a lacklustre display failed to get his side moving in the middle.
Will be kicking himself for failing to force at least a save from Adler after doing so well in the opening minutes. Dortmund's most potent threat on goal.
Showed his typical poaching skills to hand Dortmund the lead, but let himself down in a tussle with Van der Vaart that meant his game finished early.
Badly let down by his defence as Lewandowski burst through to score, but responded with a commanding, flawless display between the posts.
Rather lucky not to become the second HSV man sent off after pulling down Reus as the last defender. Defended diligently and without fuss.
Linked effectively with Aogo throughout the game, firing Hamburg's counterattacks, and also dealt well with the ever-dangerous Kuba at the other end.
Was badly at fault for Lewandowski's opener, guilty of ball-watching, but rallied from that slip to put in a solid display at the back.
Saw red for a cynical foul on Reus when the midfielder was streaking through, although his tackle may have saved an equaliser.
Was the recipient of a brutal tackle that earned Lewandowski a red card, changing the course of the game. A quiet presence, enabling Aogo and Van der Vaart to cause problems.
R. van der Vaart
More than a little fortunate to stay on the pitch in the first half, but his confrontational style and playmaking abilities unsettled Dortmund across the pitch.
An electric presence both down the flanks and in the middle. Set up Rudnevs' first strike, and was unlucky not to get his own name on the scoresheet.
A lovely, understated performance from the Venezuela international, who quietly went about his business of disrupting the BVB midfield.
Will remember this game chiefly for a wonderful solo effort that handed Hamburg a lead they never relinquished. Floated across the pitch, and always looked dangerous.
A wonderful display from the No. 10, who netted two perfectly-executed finishes to see his team through to a key victory.
