Next up for the Mariners was a trip to Welling in the National League. A hat-trick from top scorer Padraig Amond and a further strike from Craig Disley sent Town to an excellent 4-0 away win, in front of a mammoth travelling contingent.
And Paul Hurst's side kept the gun run going with a 3-1 at Weston Super Mare in the FA Trophy, followed by a 5-0 romp against Altrincham at Blundell Park. Goals from Omar Bogle, Andy Monkhouse (2), Nathan Arnold and a customary goal from Padraig Amond cemented Town's place in third position.
