Both sides showed promise in the early exchanges with Jordan Owens coming closest when he skimmed the woodwork after a quarter-of-an-hour.

The Crues did gain the upper hand, though, on 32 minutes when Chris Morrow did well to control a Marty Donnelly before directing the ball past Johnny Pollock from six yards.

And the pair teamed up again on 46 minutes when Morrow hooked home a Donnelly cross to effectively put the tie beyond Coagh's reach.

Donnelly then got his name on the scoresheet on 58 minutes with a left foot drive from the edge of the area.

He was involved again three minutes later when he supplied the cross for half-time subsitute Ross Arthurs to sweep home Crusaders' fourth.
