The Jags were looking to build on the momentum following last week’s win over Aberdeen, but could only manage a 1-1 draw away to Ross County.
Manager Alan Archibald made one change from the starting line up with Stephen O’Donnell replacing Jordan McMillan at right back.
And it was O’Donnell who had tried his luck at goal from 30 yards out. But his effort was well wide of target.
Kallum Higginbotham then saw his 30 yard free kick deflected off the visitors wall allowing Lyle Taylor a chance, but he headed wide from 6 yards.
It was a bright opening from the Jags and things were to get even better in the 8th minute.
Aaron Taylor-Sinclair found Taylor who turned Boyd and drew the foul for which Boyd was booked. 25 yards out from the resultant free kick the wall jumped and Higginbotham drove the ball low and hard into the County net past a helpless Brown.
Things could have improved for the visitors as Taylor saw his header from an O’Donnell header go wide two minutes later. But County were also still well in the game and Boyd saw his half chance saved by Paul Gallacher.
County drew level in the 13th minute after a soft free kick was given by referee Craig Thomson and Brittain curled his effort past Gallacher to level the score.
The visitors found themselves trying to play the better football, but found themselves getting dragged into a battle in midfield as both sides found the final ball elusive leading up to the break.
County started the second half with De Leeuw replacing Slew, but it was the visitors who started the half on the front foot with both Mair and Taylor having half chances early, before Chris Erskine’s right footed curling effort was inches wide of a beaten Brown.
Thistle pressed hard and Higginbotham saw a shot blocked on the hour mark after great play by Prince Buaben.
With play becoming scrappy in patches due to the nature and importance of the game it was understandable chances would be at a premium.
One of these was a great effort fired by Kiss with two minutes to go high over the bar.
