Formartine hammered Banks o’ Dee to set-up a Scottish Cup third-round clash against League 2 side Annan Athletic.
The home side started slowly and as a result of that the visitors opened the scoring in the opening minutes of the game. Michael Philipson sent through Jack Henderson who slotted home a left-footed finish from just outside of the box past the on-rushing Ewen MacDonald.
The Highland League side were struck with another blow when centre-back Jonathon Crawford had to be taken off because of an injury.
The early set-backs seemed to spark some life into Formartine and they were level mid-way through the first half as Stuart Anderson bundled the ball over the line after an excellent cross by Scott Hendry from the right-hand side.
United gained the lead only five minutes before the break. Jamie Masson sent a half-volley goal-bound from eight yards out past ex-Formartine keeper Andy Shearer.
Shortly afterwards, the home side made it 3-0 when Masson curled an effort into the top-right corner after great link-up play with Neil Gauld.
Almost straight from kick-off the visitors grabbed a goal back after Josh Winton’s header found substitute Craig Buchanan only a few yards out and he slotted the ball past MacDonald.
The first half still wasn’t done there as the home side re-gained their two-goal advantage after ex-Deveronvale defender Kieran Heads brought down Scott Barbour for a penalty, which Gauld buried low to his left sending the keeper the wrong way.
The second half certainly didn’t start with the same intensity as the end of the first with very little chances falling to either side.
With 15 minutes to go United extended their lead with a bullet header from Graeme Rodger from eight yards out after a superb delivery from Scott Ferries.
That goal again sparked the life into United and Barbour soon made it 6-0. Ferries produced a delightful flick that sent Barbour one-on-one and he put the ball under the legs of Shearer.
The home side still weren’t finished inflicting pain into the visitors as Shearer brought down Barbour and Masson slotted home from the spot to cap off a superb result for the home side as well as securing his hat-trick.
