Manager Danny Lennon was full of praise for his St Mirren team as they picked up their first win of the season against bottom-of-the-league Hearts.
He said: "There were a lot of questions asked of my players ahead of the game; would they stand up to the crowd, would they stand up to the pressure?
"A lot of people thought we would come here and crumble but we stood tall.
"At times like this, character gets you through and I know that I have that in abundance in my dressing room."
John McGinn and Paul McGowan were on target for the visitors either side of the interval as near-15,000 crowd gave noisy backing to the hosts.
And the 2-0 triumph lifts the Paisley team up to 10th spot in the Premiership, above Kilmarnock and 12 points clear of administration-hit Hearts.
"It's a big result for us," added Lennon, who had been pleased with Monday's 1-1 draw at home to Aberdeen.
"It's nothing more than the players deserve.
"We asked them to go and continue where they left off on Monday evening.
"They did the little things very well and I'm delighted that they applied that desire and hunger once again.
"In terms of chances, we certainly had the better of them.
"They finished the job off today and have been rewarded with three very valuable points."
Lennon's position has been the subject of much scrutiny, with St Mirren struggling for form since they lifted the League Cup back in March.
"I'm a fighter and that group of players are fighters," he added.
"I have a very talented group here and when the group brings that work-rate, commitment and organisation we can start to climb the table.
"It's a small step and we'll look to build on that after our slow start.
"I try not to get too low when things aren't going well and it will just be business as usual on Monday morning.
"The target is to go and win the next game. It's a simple as that."
