Pools fell behind early when Sam Hoskins slotted between the legs of debutant Nicholas Bilokapic who replaced Ben Killip in goal.
And Graeme Lee’s side had no way back in the second half when substitute Chanka Zimba was able to power home from close range from Mitch Pinnock’s freekick.
Pools had chances of their own in the game but came away empty handed as the Cobblers held on to the third automatic promotion spot in the table.

Tough afternoon. Booked early after struggling to deal with a ball from Odusina. Missed clearance led to the second goal. Subbed. Picture by FRANK REID
