It took the home side just thirty seconds to threaten in front of the returning home fans. Zak Rudden’s interchange with Ross Docherty led to the Thistle captain forcing Dumbarton number 1 Sam Ramsbottom.
From the offset, the tempo became high, despite the 27( edit degree sign) weather with the Jags at the forefront of the action.
In the 30th minute, the game kicked into life with Chances for both sides.
A well-worked corner landed at the feet of Gregor Buchanan but the Sons defender was to be left frustrated as his effort was cleared off the line by the retreating Ross MacIver.
Breaking from the clearance the Jags worked themselves into their own opportunity from a corner. Kevin Holt rose above everyone to head low, forcing Ramsbottom into a strong save.
With the last touch of the first half Thistle were the team to take the lead. An expertly chipped cross from Ross MacIver was met at the back post by Brian Graham, nodding back across goal into the Sons net.
Eight minutes after half time it would be that man again, Brian Graham. A swift break sent half time substitute, Conor Murray, down the left flank. Beating the Sons defence, he found the Jag’s number nine on the edge of the box to stroke home into the bottom right corner.
Soon after it could have been three. MacIver’s cross from the right found Zak Rudden free in the 18-yard box, however, he failed to sort his feet out, sending his effort wide of the post.
The home side were lucky not to be down to ten men in the 70th minute. Preceding a scuffle for the ball, Richard Foster looked to have flown high into a challenge with Conner Duthie, escaping with just a yellow.
The home side ended the match creating numerous opportunities from the flanks but couldn’t find the end product. The pick of the bunch seeing Ross Docherty denied a clear cut opportunity after being blocked by the charging Ramsbottom.
Dumbarton were handed the chance of consolation on the stroke of full time after a moment of madness from the Jags defence led to an indirect freekick awarded in their own box. Redeeming himself from the mishap Jamie Sneddon continued his heroics from last season, stopping a point-blank drive to keep his clean sheet intact.
A comfortable home win sees Thistle go to St Mirren Park on Sunday looking to cause an upset as the visitors bow out of this year’s competition.
