With a place in the final at stake, neither side was to give an inch in this second semi final. It was a war of attrition as both sets of players and fans contributed to a highly charged contest at Meadow Park. in the end Thistle had just enough to hold off Tower Hearts and book their place in the Airdrie final, courtesy of Chris Kelly's early header.
Having drawn first blood, Bonnyton would have hoped to establish some momentum in the game, but Tower recovered from a slow start to make them work for the win. In a match of few clear cut opportunities they will wonder what might have been after striking the woodwork twice late on.
Hearts set themselves out determined to push their full backs into the attacking third but were caught cold for the opener as Bonnyton crafted a fine flowing move down the right. Kyle Gilroy found some space down the flank and his cross was inch perfect for Kelly at the far post, stealing a yard on Sean McCall to head past Calum McBain for the opener.
You might thought a goal would be starter for a few more, but what followed was something of a midfield stalemate, as both sides struggled to get hold of the ball and get on top. It was no less of a contest though as both sets of raucous fans roared on the ensuing midfield tussle.
After their slow start, Hearts began to grow into the game, continuing to drive their wing backs forward at every opportunity. McCall was still encouraged to get into the attacking third with a couple of shots to test Scott Purdie in the Thistle goal. Along with this Connor Brannigan was also running the channels for his team to provide some rays of hope for the Shettleston side.
For all of that neither side was succeeding in crafting clear cut chances and the game became something of a physical chess match. Bonnyton almost found a way through the Hearts rearguard on the half hour as Ewan Barrie decided to take the initiative with a driving run at the defence. He set up Gilroy, who shot narrowly over.
3 minutes later McBain clung on well to Andrew Strachan's powerful shot from just outside the box as Bonnyton continued to threaten. As the clock ticked down to half time, Hearts were perhaps shading it in terms of possession, but Thistle were carving out the best of the limited opportunities, and crucially they retained their one goal advantage at the break.
