Ballynahinch Albion 2 – 3 Castlewellan III
The Albion returned to action after a 12 year absence with a squad full of youth, littered with splashes of experience and Matthew Lindsay’s first game in charge.
Unfortunately, they found themselves behind early on, and were soon three down after half an hour, despite Castlewellan being reduced to ten.
But Ben Maxwell scored twice before half time to give The Albion hope of a comeback.
However, in the second half they couldn’t take advantage of having an extra man, and the game petered out.
It was an encouraging performance from the side with six teenagers starting and debuts for Charlie Parkinson, Greg Blunt, Pearse Irvine and Nathan Cheevers.
Player of the Match: Ben Maxwell
Line up: Anthony Greene [C], Charlie Parkinson, Ryan Rooney, Will McNeill, Greg Blunt, Ethan Perkins (Matthew Lindsay), Callum Greene, Pearse Irvine (Richard Annett), Nathan Cheevers (Matthew Tate), Ben Maxwell, Kyle Steenson.
