Diouf nets twice for Molde
Second-placed Molde moved to within seven points of leaders Rosenborg with a 3-1 home win over Aalesund.
Pape Diouf's first-half brace sent them on their way and Mattias Mostrom sealed matters ten minutes from time, immediately restoring the two-goal cushion after substitute Khari Stephenson had pulled one back.
Aalesund's bid to find a way back into the game was not helped by the 73rd-minute dismissal of Demar Phillips.
Elsewhere Lillestrom edge Stromsgodset 2-1. Steinar Pedersen and Edwin Eziyodawe found the net in the first half and their side held on despite Oyvind Storflor's late consolation.
