UCL Premier Division: Holbeach United 5, Harborough Town 0
Holbeach bounced back from their disappointing FA Vase exit to inflict a first defeat in seven on the Bees.
It took 38 minutes for the Tigers to break the deadlock with a Jake Clitheroe goal.
Two minutes later Lee Beeson doubled the lead, expertly converting a spot kick he had won himself.
The outcome was all but settled two minutes into first half added time when Jordan Thomas found the net for number three.
Beeson doubled his personal tally after 73 minutes and Gary King completed the nap hand a minute into time added at the end to round off a dominant display.
Third-placed Holbeach will be confident of another three points on Saturday when travel to UCL premier division strugglers Oadby Town.
