Hertha took the lead after just four minutes through Roman Hubnik but then fell behind to a quick-fire double from Srdjan Baljak, before Sandro Wagner resuced a point for Jos Luhukay's team after a thrilling second half.
Duisburg caught cold
Hertha's form has picked up in recent weeks, and it showed as they raced into the lead inside just four minutes. Brazilian midfielder Ronny's free-kick deflected off the wall, but it was Hubnik that reacted quickest to the loose ball and coolly beat Felix Wiedwald from close range. The game swung from end to end and the first chance for the home side arrived in the 15th minute when Andre Hoffmann went within inches of converting Maurice Exslager's cross, before Anis Ben-Hatira then missed two gilt-edged opportunities to increase Berlin's lead just before the interval.
Whatever Duisburg coach Kosta Runjaic must have said at the interval, it worked a treat as his players upped the energy levels and had soon turned the game on its head. It was veteran striker Baljak that hauled them back into the game with two predatory close-range finishes, as Hertha struggled to cope with the hosts' direct approach. Luhukay's side remained dangerous, however, and grabbed an equaliser of their own against the run of play when Wagner steered home Ben-Hatira's cross to score against his former club. Both sides had chances to win it at the death, but an entertaining game finished all sqare at 2-2. Duisburg remain rooted to the bootom of the table, while Hertha are up to sixth place.
