AFC Rushden & Diamonds booked their place in the fourth round of the FA Vase with a 2-0 win over Graham Street Prims at the Dog & Duck.
Diamonds made the breakthrough on the stroke of half-time when Fazel Koriya pulled the ball back for Matt Gearing who fired home.
And they wrapped it up in stoppage-time when substitute Deven Ellwood tapped home after a shot was saved.
Diamonds will now be in the fourth-round draw, which will be held on Monday lunchtime.
Diamonds: Cross, Merrill, Brown, McBride, Harris, Deakin, Gearing, King, Dunkley, Koriya, Ling. Subs: Brown, Bunting, Ellwood, Taylor.
