Northampton climbed into the League Two play-off places with a 2-1 victory over 10-man Grimsby.
Adebayo Akinfenwa's 15th goal of the season sealed the points in the 66th minute, shortly after Grimsby centre-back Oliver Lancashire had been sent off for an apparent elbow on Billy McKay.
The Cobblers had earlier taken the lead through Liam Davis, only for Michael Coulson to pull the hosts level three minutes before the break.
Davis` opener came in the 14th minute, the midfielder finishing confidently after Akinfenwa had slipped a neat ball into his path.
Jamie Devitt created the equaliser when he cut in from the left before feeding Coulson, who let the ball run across his body before placing a firm right-foot shot past Jason Steele.
Lancashire then received a straight red from referee Anthony Taylor when he blocked McKay on the right.
And the Cobblers made their numerical advantage pay when Akinfenwa headed home a Luke Guttridge cross at the far post.
