The road to the Millenium Stadium Cardiff began for Aylesbury at Kent League side Beckenham Town.
Another poor United display saw the home side unlucky not to take the lead following a glaring miss as early as the tenth minute.
Neither side created much in the way of chances in the remainder of the first half, although at times Aylesbury were outplayed by their lower league rivals.
The second period continued in a similar vein, before the Ducks finally broke the deadlock with just fifteen minutes remaining. Gary Wotton netting from close range from a corner.
By no means a classic, but as they saw a win is a win.
