St Mirren manager Danny Lennon felt his side were more than worthy of the three points after posting a 2-0 win over Hearts in the Clydesdale Bank Premier League.
Jim Goodwin fired a superb 35-yard strike beyond Jamie McDonald seven minutes before half-time to give the hosts the lead, and Lewis Guy doubled their advantage three minutes after the interval when a lightning fast counter-attack ended with Steven Thompson cutting the ball back for the striker to blast into the net.
"I'm delighted with the performance," said Lennon. "We had spoken about the fact we hadn't beaten Hearts last season and what it would require mentally for us to get that win. The manner and the level of performance was pleasing."
He added: "To be fair to Hearts they got out the traps well and made things difficult for us, but we passed that test and I felt we looked in control of the game and mentally looked very comfortable."
Victory lifted the Buddies to third place in the table and was their first home league win of the campaign.
Lennon also praised Goodwin for his opening goal and for maintaining his discipline despite picking up a yellow card in the first minute of the match.
"We got the opening goal through an excellent strike from Jim," said Lennon. "In the past I have had to be cautious with him after he received a caution, but he showed he's progressed and came through the remainder of the game."
Hearts boss John McGlynn was pleased with the level of performance from his side, even though the result went against them.
The Tynecastle side threw men forward during the second half but struggled to threaten Craig Samson's goal.
"I'm disappointed at the result but not the performance, if you get a goal early on then it's a different ball game - unfortunately we weren't able to do that," said McGlynn. "The second goal was a bad one to lose, our guys kept working hard though and kept playing football, however we just couldn't get the ball in the back of the net."
