St Mirren manager Stephen Robinson: "It's disappointing after the run we've been on.
"It's two second-phase set plays, I didn't see Dundee scoring. They went very direct, which is their prerogative in these conditions.
"These are the hard ones after the euphoria of the other night [against Rangers].
"It looked like a tired performance but we've been on a very good run. This doesn't take away that it's still one of the best starts [to a season] in a long, long time."
Dundee manager Tony Docherty: "I'm massively proud of the players and the team.
"Within 20 minutes we lost both centre backs and the easiest thing for the players to do was to feel sorry for themselves but they dug out and got a result.
"At half-time I said: 'we need to do more, we need to win ugly,' and we did that.
"I couldn't be more proud of the players. Some wins are bigger than others and I think that's a big win."
