Mainz and Hamburg played out a goalless draw on Saturday which helped neither side with their respective agendas.Mainz slipped to seventh in the standings after creating just one big chance against a Hamburg side who are not yet mathematically safe, but who can have few complaints after also only creating one chance at the Coface Arena.Mainz's best opportunity came after an even half an hour in which both sides had largely cancelled each other out.It was Karim Onisiwo who got in the first shot of the game, but Jaroslav Drobny got down to make a save.Loris Karius responded to two tentative efforts at the other end to deny Johan Djourou and Nabil Bahoui before the break.Hamburg's best chance came five minutes into the second half, meanwhile, when Sven Schipplock robbed Niko Bungert of possession and was left with only Karius to beat, but the Mainz custodian made a great save to deny him.Jhon Cordoba could have snatched a win for Mainz late on, but his shot wide was emblematic of a game in which neither side deserved to take more than a point.
