St Mirren manager Stephen Robinson tells BBC Scotland: "We could have made it more comfortable for ourselves, but we continued to pass the ball and make chances. Dundee owe Trevor Carson, he made a few stunning saves to keep the score down.
"Dundee are a tough nut to crack. They have a lot of experience, they know how to win, and we had to make sure we weren't going to be done by a set piece or counter attack.
"To a man, our organisation was excellent. It was important to follow up Saturday's result and performance. We're going into games with confidence and belief that we can get points.
"Nothing is done at this stage. We have a lot of tough games coming up. Nothing is easy at this level. We need to do the basics right, we've done that well recently."
