Dundee made four changes Vontae Daley-Campbell came straight in for his debut. Niall McGinn was given his first start, while Charlie Adam and Danny Mullen returned. They replaced Christie Elliott and Luke McCowan, who were on the bench, and Paul McGowan and Leigh Griffiths.
Both teams started well and Max Anderson had a couple of strong runs, and just about played in McMullen who just failed to get a clean shot in. Ryan Sweeney just missed the goals with a decent header.
Paul McMullen had a fine header saved by the United keeper to keep it 0-0 at half-time was soon after.
Second half and Dundee started well and pushed United back, good play from McGinn got him into the box but he failed to find a team mate. McMullen had a good effort saved as Dundee looked for the vital first goal.
Soon after Dundee made twin substitutions after 61 minutes gave the Dark Blues an additional burst of energy. Zak Rudden and Luke McCowan came on for McGinn and Adam. Jordan McGhee had replaced Daley-Campbell a couple of minutes previously.
Dundee came close in the last 20 minutes, when twice the ball was cleared off the line. First a Zak Rudden deflected shot was headed off the line, from the corner a Fontaine shot was cleared off the line.
In the last few minutes United had a great chance but Clarke somehow missed the goals from a few yards out.
