The Development Squad moved up to third position in the Cumberland County League table following an emphatic win over the team who started the day in second spot.
But it was Unisun who opened the scoring with Dave Barnes netting the first after ten minutes.
Top scorer, Josh Palmer, levelled matters just five minutes later and Cain Pears added another to put the young Reds ahead at the break.
It was plain sailing after that and Lee McCullough’s side ran out comfortable winners with Luke Whitehead coming off the bench and scoring his first two goals for the club, before Pears netted his second of the afternoon just before the final whistle.
Shane Dorward netted Athletic’s second.
Team: Aaron Lister, Ben Wade (Luke Knowles, 70), Dan Whitehead, Owen Birkett (Robbie Wilson, 35), Zach Martin (Hayden Rae, 60), Hayden Percival, Zach Lester, Cain Pears, Josh Palmer, Jack Brown (Luke Whitehead, 60), Jack Dunstan (Ben Davidson, 60).
