Partick Thistle 2, Airdrie 1 (agg 4-3): Graham sinks Diamonds' dream

Airdrie's dream of back-to-back promotions ended at Firhill this evening as a Brian Graham-inspired Partick Thistle booked their semi-final slot against Raith Rovers next week.

It's an 11th straight defeat for the Diamonds in Maryhill, in a game that they looked lively in from the start.

However, Graham wasn't flagged offside for his first goal when he should have been in 18 minutes, and that took the wind out of Airdrie's sails, with the veteran striker making sure of the win just 90 seconds into the second half.

Arron Lyall pulled a goal back for Airdrie 10 minutes into the second half, but it proved to be consolation.

Airdrie had been the better side up until the opener, with plenty of possession and pressure, but not that much to show for it.

Graham is lethal in the penalty box, however, and the Diamonds defence stopped, expecting a flag that didn't come.

They were then caught napping early in the second half, as Thistle grabbed the game by the horns.

Lyall pulled a goal back for Airdrie, but it wasn't enough for the Lanarkshire side to force their way back in.

Thistle boss Kris Doolan kept faith with his line-up from Tuesday night.

His Airdrie counterpart Rhys McCabe made one change, to his side at New Broomfield on Tuesday night. Captain Adam Frizzell was replaced by Arron Lyall, with Cammy Ballantyne taking the armband.

Airdrie started well but it took until the sixth minute when Callum Fordyce blasted over from outside of the box before they made anything really happen.

Thistle were hemmed in during the opening stages, with Kanayo Megwa and Mason Hancock causing problems down either flank.

Ben Stanway had a go for Thistle from just outside the box, but it was well taken at the left post by Robbi Hemfrey in 17
