Bell was shackled all through by Scotstown’s Kieran Hughes but popped up late to break Scotstown hearts and send his club through to the semi-final, where they meet Crossmaglen or Kilcoo.
Scotstown led at half-time 0-5 to 0-4, Ballinderry fighting back to parity before Scotstown had the last say of the half through Kieran Hughes. By the 42nd minute Scotstown led by four thanks to efforts by Brian McGinnity, Darren Hughes and Shane Carey. Ballinderry cut the deficit to a point after 17 minutes with two Colin Devlin frees and one from Conleth Gilligan before striking for the only goal through sub Darren Conway.
