Ben Strevens made Wycombe's hard work in getting the game on worthwhile with the late winner in a 2-1 victory over Hereford.
But it was tough on the Bulls who had deservedly levelled through Mathieu Manset after Gareth Ainsworth's first-half strike.
Hereford adapted quickly to the conditions and had the better of the opening action with Nicky Featherstone and Manset going close before Rob Purdie's deflected drive came back off the bar with Nikki Bull beaten.
Wycombe gradually forced their way into the game and, with Purdie forced off with a hamstring injury, Kevin Betsy began to make use of some space down the left.
Two minutes before the break one of his crosses reached Ainsworth who drove a shot through a crowd of players and into the far corner of the net.
Ainsworth's cross was headed just wide by Stuart Beavon and Chris Westwood had a goal disallowed as Wycombe piled on the pressure at the start of the second period.
Hereford struck back 12 minutes from time when Manset clipped in Joe Colbeck's cross.
But Strevens had the last word, crashing in Beavon's cross two minutes from the end.
