Adebayo Akinfenwa's brace helped Wycombe claim a 3-2 victory over 10-man Grimsby.
Akinfenwa and Joe Jacobson put the Chairboys in control at Blundell Park before a penalty from Mitch Rose and goal from JJ Hooper saw Grimsby, who had Danny Collins sent-off for two bookable offences, draw level.
But with 15 minutes left on the clock, Akinfenwa found the net for the second time to hand all three points Gareth Ainsworth's men.
Chances were few and far between in the opening stages but a trademark run from Siriki Dembele nearly brought an early reward for Grimsby.
As the clock ticked towards 30 minutes, Akinfenwa found half a yard in the home box - and duly prodded home the opener.
Jacobson made it two with a calm penalty, and Rose did likewise at the other end.
A stunning long-range strike from Hooper put Grimsby back on level terms, but after Collins was given his marching orders for the home side in the 58th minute, Akinfenwa had the final say with a header.
