Dunfermline manager Jim McIntyre hailed the attitude of his team after their first win of the SPL season.
"I'm ever so proud of the players," McIntyre said after the 1-0 win at St Johnstone. "They were excellent and showed great determination.
"When we were down to 10 men St Johnstone piled loads of pressure on us and we dealt with it admirably.
"The players have got great character and spirit in the dressing room and that will take us a long way."
The Pars are unbeaten in three league matches, having opened with draws against St Mirren and Inverness.
"We won't get carried away," McIntyre continued on BBC Radio Scotland. "We've started the season well but it's only three games in and there is a lot of hard work ahead of us."
Andy Kirk netted the only goal in a game of few chances and McIntyre was delighted with his lone striker's contribution.
"He's a sniffer," he said of the Northen Ireland international. "He's a penalty box striker and he knows how to get himself into goal-scoring positions.
"It was a corner we worked on and happily it's paid off today."
Paul Gallacher was the other hero for Dunfermline, saving a penalty from Liam Craig after John Potter had been sent off for a trip on Francisco Sandaza.
"Paul made a fantastic penalty save again, he did that in the first game against St Mirren, and he also had one or two other saves," explained McIntyre.
"We're lucky to have two good goalkeepers. Chris Smith was integral part of of getting us promoted last season."
On the red card decision, the manager added: "I'd need to see it again but the boys are saying we had a man round and he definitely wasn't the last-man.
"If that's the case, we'll appeal it but it was a penalty by all accounts, so no complaints about that."
