Guest Randers took the lead in the 36th minute through Simon Piesinger, who outwitted Sweden's William Eskelinen with a long shot. And Carlgren's team long looked to take three heavy away points against rival Århus.
However, the home team got the last word. Jakob Ankersen found Patrick Mortensen with an oblique inward-back pass at extra time. The striker outlasted Carlgren with a low shot and became the point-saver for the series tri.
Randers is seventh after 24 games played.
