Hertha Berlin took all three points from their trip to Augsburg with a Salomon Kalou penalty enough for a 1-0 win in a game which saw both sides reduced to 10 men.Augsburg forward Raul Bobadilla was sent off for a second yellow-card offence before half-time, with Roy Beerens following for the guests midway through the second half.By then, Hertha had taken the lead after Ragnar Klavan fouled Kalou, who stepped up to beat Marwin Hitz from the spot in the 48th minute.Alexander Esswein rattled the post with a free-kick as Augsburg looked in vain for an equaliser, continuing their habit of starting the season with a defeat under head coach Markus Weinzierl - like in their last two seasons when they went on to lose their opening two league games.ends
