Lonneke needed this performace, after a rather weak period...
By the way, Hamburg should end 6th, for personal interest of a certain forummember
If my set ratio maths is right, münster need a result two sets better vs stuttgart than hamburg achieve vs potsdam, in order to finish above hamburg. So if hamburg win 3-1 or 3-0 then they are in, otherwise the other match comes into play.
Of course münster don't necessarily need to finish above hamburg because (as Matthias pointed out) they could both finish above stuttgart.
Incidentally there are no golden sets this year as playoffs will be determined on a best-of-three basis (best-of-five for the final two). The same goes for pre-playoffs. Higher-ranked teams will get first home advantage (and also therefore in the decider, if needed).
