WISBECH St Mary Ladies beat Outwell Swifts 3-0 and now need only eight points from four games to clinch the league title.
Saints took the lead before half-time with Faye Kowalewsky scoring from a tight angle.
After the break Kyra Clarke ran half the length of the pitch to add a second goal.
Outwell pushed hard to try and get back in the game but with some very good saves from Saints keeper Carly Oakley and good defending kept them at bay.
Jo Warren sealed the win when she half-volleyed from 25 yards out.
