Hertha Berlin striker Adrian Ramos's third goal of the season was enough to give his side all three points against Hamburger SV in the Bundesliga.
It was the visitors who started stronger, Lam Zhi Gin and Artjoms Rudnevs both tested Thomas Kraft in the Hertha goal.
Hertha then came into the game and the in-form Ramos should have done better with a header, but he could not find the target.
Near the end of the half Rafael van der Vaart came close to breaking the deadlock, but his effort on the turn was parried away from the bottom corner.
Hertha started to get on top of the game in the second half and managed the vital breakthrough as Ramos turned in from close range.
Hamburg were unable to find a leveller, with Hertha taking their second win of the season.
