Pádraig Amond scored two goals in the same match the first time he ever scored in an FA Cup competition .
His first came on 34 minutes when Conor Townsend beat three defenders , breaking into the box and playing the ball across for Amond to drive home ; he scored the fourth goal for Grimsby in the 71st minute when substitute Jon-Paul Pittman played a one-two with Amond who found space in the box and side-footed home ; his first goals in FA Cup competition .
