The Johnstone side topped the group with two wins and a draw over rivals Giffnock North, who they pipped with their superior goal difference.

And manager James Donnelly was delighted to secure an unbeaten run in the section 8 of the group stage.

He said: “We have been battered by holidays and suspensions for the first few weeks but we have managed to rally round and progress to the quarter-finals which was the aim at the outset.

“Fourteen goals scored in three games proves that we have a threat going forward and hopefully we can only get stronger from here on in.

“The squad has been stretched but everyone has done what’s been asked of them.”

The scoreline flattered the Glasgow side and Thorn should have been well out of sight by the interval.

Craig McMahon opened the scoring after three minutes but Thorn were soon pegged back when slack defending once again allowed Weirs to level.

However a free-kick was awarded 25 yards out and Paul Young stepped up to curl a lovely shot around the wall and into the corner of the net to restore the lead.

From then on it was one way traffic with McMahon, Tom Smith and Ryan Crawford passing up gilt-edged opportunities.

But soon after the restart McMahon finally made it 3-1 and put the game beyond doubt.

Darren Lamont nodded in the fourth from Young’s corner before Liam Allen made it five.

Chances were aplenty and boss Donnelly rang the changes replacing keeper Liam McWilliams with brother Tony and introducing Johnny McEwan and flu-hit Dean Scott.

Scott didn’t take long to get on the scoresheet with number six after some fine play down the left.

And Ross Horne rounded it off with a goal five minutes before time against deflated opponents.

A solid display at the back and plentiful goalscoring opportunities
