Thistle coach Craig Stirton said the Jags played some good football and created numerous chances.
Everyone put in a good effort, he said.
Thistle’s man of the match was Shehab Altour, who started on the left wing but moved into the middle of midfield.
“Tim Hofman wasn’t feeling well and had to come off at halftime,” Stirton said.
“He’d been centrehalf, so we pushed Raydon Semmens from defensive midfield to centrehalf, and Shehab from the wing to central midfield. Lucas Ricard came on for Tim but played on the wing, where Shehab had been.”
At halftime, Andre Riley was shifted from leftback to left wing, and Ricard moved to leftback.
Others to shine for Thistle were Reece Brew and Ure in central midfield, Brad Hill at centreback and Tom Talbot in goal.
“When we were a goal down I pushed Davie up with Sam Patterson,” Stirton said.
“It paid off. Davie drew the foul for the penalty, and then he scored from it.”
Thistle Reserves are now seventh in the eight-team league. They have three games go to in their 14-match programme, and have five points from a win and two draws.
