Stephen Robinson heaped praise on his entire goalkeeping department for helping the Saints squeeze past Dundee.
The Buddies were well below par in their Scottish Cup fourth round tie but hung on to reach a penalty shoot-out.
Trevor Carson pulled off three superb stops to help the Paisley side sneak into the hat for the next round, with boss Robinson giving credit to his number one and St Mirren goalkeeping coach Jamie Langfield, who did his crucial homework on Dee’s penalty takers.
Robinson said: “Ultimately what we got out of that is we’re through to the next round.
“We weren’t at our best obviously - that goes without saying.
“As a team we made poor decisions on the ball and we hold our hands up to that.
“But in the cup you just need to get through and we’ve got through. Trevor made three excellent penalty saves and deserves a lot of credit.
“And so does Jamie Langfield because he called Trevor over just before the shoot-out and gave him info about every single Dundee player and what way they were going to go with their penalties.
“And he got every one of them right. So big credit to Trevor and to Jamie.
“Trevor thinks he should save more in league games. We’ve had a lot of penalties against us and I don’t think he’s saved any. He certainly made up for that.”
