Full time at Haig Avenue:
Southport 1 Hereford 4
Alex Babos (2) and Andy Williams after Lewis Hudson had put the Bulls ahead midway through the first half.
Southport equalised after two minutes so the score was level at the break.
But the introduction of Babos and Williams inspired Hereford.
Babos scored from a free kick. Then doubled his tally before Willo completed the scoring.
Hereford are now 7th, unbeaten so far.
