David Wotherspoon came off the bench to powerfully head home a deserved 79th-minute winner following Lewis Stevenson's driven cross. Leigh Griffiths and Alex Harris were earlier taken off, signalling their importance to the team, while Kevin Thomson and Eoin Doyle were rested after playing in the 3-1 midweek win over Kilmarnock.
Fenlon made seven changes for his team's final Clydesdale Bank Premier League game with regular starter Jorge Claros impressive in midfield. But the likes of Stevenson and Tom Taiwo did their Hampden prospects no harm either. Fenlon said: "They gave me plenty of headaches but that's what I wanted."
He added: "I asked all the players to make sure, if they got an opportunity to play then they give themselves a chance to get in the squad. It should be a good week, training should be lively. Everyone will want to be in the team and there should be a good tempo."
Fenlon went on to say: "Players will miss out, that's just the nature of the game. You can pick 18 for league games and 16 for the cup, which is unusual. I have to make harsh decisions but I make them in the interests of the club. That's all I think about, what's the best squad to win the game."
One player who has catapulted himself into contention since the semi-final win over Falkirk is 19-year-old centre-back Jordon Forster, who delivered a solid and assured display in the continuing absence of the injured James McPake and Tim Clancy.
"He was very good again, I thought him and Paul Hanlon worked very well," Fenlon said. "They again came up against some decent players and I was very, very pleased with them. He has got some good experience around him and it was good to get Ryan (McGivern) back in for some game time."
McPake (back) and Tim Clancy (groin) are both set to join their team-mates when they return from a break on Tuesday to prepare for the final.
"James did a little bit on Friday, Tim did a bit more," Fenlon said. "They should be okay to train on Tuesday. They will train during the week and then it's decision time I suppose.
"If they are in any way doubtful, we won't risk them. If they show their fitness then I have got to make a decision."
