In the early kick off at Ferrycroft Park, Lairg Rovers had put three past Thistle after just 20 minutes. Liam Mcleod opened the scoring with a good finish from six yards on the end of a Michael Newlands cross. Michael Newlands doubled their advantage four minutes later when he pounced on a loose ball and rounded the keeper. Newlands netted again on twenty minutes getting on the end of a clearance from Craig Ross, but shorty after, Thistle reduced the deficit with a goal following a penalty award for a foul on Finn As-Chainey; Liam Rostock putting away the resultant spot kick. Lairg remained undettered in their first half assault though, and Adam Mackay added a fourth before the interval, scoring with a neatly hit volley which cannoned in off the post.
Thistle stemmed the tide in the second half and on 55 minutes, Darran Goller reduced the scoreline to 4-2 after rounding the keeper. The comeback continued as Goller netted again just five minutes later heading home a Cammy Mackintosh cross, leaving just a goal between the sides. The Jags were given further hope when Craig Ross was red carded with half an hour remaining — but there was to be no equaliser as the home side held on to advance to the semi-final.
