Bitter disappointment followed a gasp of relief after Kilmarnock made it 1-1 in the dying minute of Thistle’s latest home game.
Kallum Higginbotham won a corner within the first 60 seconds but shot it over the bar.
Thistle though didn’t have too long to wait for the opening goal with it arriving in the third minute.
A Stephen O’Donnell long throw from the right caused the Kilmarnock defence problems with Higginbotham squeezing an acrobatic overhead kick into the net.
Thistle continued to dominate until for the next half an hour with the visitors making very little impression against the home defence.
It took them until the 35th minute to fashion even a half chance and even then Robbie Muirhead’s mis-hit shot flew calmly into the waiting arms of Paul Gallacher.
The early stages of the second half followed very much the same pattern as the first and in the the 65th minute Higginbotham again got in on the action but couldn’t find a Thistle player with his cutback.
However in the final quarter Kilmarnock came more into things and in the final 10 minutes Thistle’s nerves starting to jangle when Kilmarnock had their first clear cut look at the Thistle goal.
William Gros proved a real headache when he managed to get just ahead of Taylor-Sinclair inside the Thistle box and a clip on Gros’ ankles was enough to give Kilmarnock a penalty. Taylor-Sinclair was read carded and Kris Boyd took the penalty which was knocked back out by Gallacher, but Robbie Muirhead was the quickest to react it and tucked it home.
