FC Utrecht and Groningen shared the spoils in a goalless draw on Friday night as the hosts' home frustrations continued.
Dick Advocaat's side enjoyed the edge in a tight match of few chances, but could not find a goal to end a winless run at home which dates back to December 9.
Victory could have taken Utrecht level with fifth-placed Vitesse Arnhem but Groningen's good form continued as they made it six Eredivisie games without defeat.
They have now taken 17 points from their last eight outings to climb well clear of trouble at the foot of the table, sitting just five points behind Utrecht.
