DAYLE Southwell scored within 90 seconds of coming on the pitch to send Grimsby Town into the third round of the FA Trophy this afternoon.
The young striker entered the fray as an 85th minute substitute and struck the decisive blow moments later.
Earlier, Andy Cook’s seventh minute header, from Paddy McLaughlin’s fine corner, separated the sides at half-time.
However, Keanu Marsh-Brown equalised for the Bees 16 minutes from time, and extra-time loomed until Southwell struck with a fine finish.
Jake Hyde then struck the Town post deep into injury-time as the Mariners held on.
Town: McKeown; Bignot, Thomas, Doig, McDonald; Thanoj, Disley, McLaughlin, Colbeck, Rodman; Cook.
Subs: Hatton, Pearson, Southwell, Neilson, Winfarrah.
