Harborough 0, Deeping Rangers 4
These two sides were involved in FA Vase upsets three days before but there was no surprise in this UCL Knockout Cup contest on Tuesday evening.
Deeping took a first half lead after 14 minutes with a Matt Heron header from a Mitch Griffiths cross.
Luke Peberdy missed a good chance to put the Arrows on terms.
The contest was settled by two goals for the visitors in the space of a minute.
Alex Beck intercepted a Grant Davies clearance to slot home after 67 minutes and Heron netted his second a minute later, confidently finishing after latching on to a headed clearance.
Ryan Oliver completed the scoring from a David Burton-Jones through ball in the last minute.
Deeping: Doughty, Flack (Oliver), Parker, Forbes, Ashton, Burton-Jones, Griffiths, Odain, Beck (Ginty), Heron (Gilbert), Moreman.
