Northants ladies will take on Essex in the quarter-finals of the Johns Trophy this weekend.
The county secured their spot in the last eight by taking 18 points from their final group match against Suffolk at Felixstowe & Suffolk BC.
Northants had four winning rinks in their narrow 116-115 victory with the highest scoring being the one skipped by Rebecca Wigfield which triumphed by a 10-shot margin.
The county will now travel to the neutral venue of Littleport BC in Cambridgeshire for their quarter-final clash on Saturday (1pm).

Northants men just fell short in their efforts to reach the knockout stages of the Middleton Cup.
Needing to win on all six rinks in the final group match against Huntingdonshire while hoping other results went in their favour, the county produced a fine effort as they secured five rink victories to seal an overall 134-110 success.
But it wasn’t quite enough to take them into the knockout rounds.
