Dundee were delt a blow when Tyler French was injured and it took six minutes of treatment before he left in a stretcher. Max Anderson was a straight replacement.
St Mirren had two shots on target but was easy for Dundee goal keeper Adam Legzdins. Dundee grew into the game and after good play Mulligan had a shot saved by Carson in the saints goal.
Max Anderson then had a shot were saved and from the corner Ashcroft headed wide. Dundee lost Cammy Kerr to injury. Lyall Cameron came on to play in midfield with Josh Mulligan shifting to right back.
Cameron almost scored a quick opener with a clever volley from Jordan Marshall’s cross, but Trevor Carson pulled off a great low save.
Second half and Saints had a wee spell but failed to trouble the Dundee defence and Dundee played some nice play but failed to create a cut clear chance.
Cillian Sheridan and Kwame Thomas for Alex Jakubiak, and McMullan to give Dundee more height up front. It was no surprize that the 90 minutes ended 0-0 and forced extra time.
Dundee put on Zak Rudden for Luke McCowan to give Dundee fresh legs, Dundee had a go but the only real chance was after Thomas flicked on Cameron’s free kick, but Carson saved.
Saints hit the post near the end as the game would be settled by Penalties.
St Mirren went first and Eamonn Brophy’s weak effort was saved by Legzdins. Dundee’s first three penalties were all better efforts, from Rudden, Thomas and Cameron, but Carson pulled off three great saves. O’Hara, Grieve and Kiltie converted – and that was the end of Dundee’s Scottish Cup campaign.
The team all put in a shift today and gave it their best the injury to Tyler and losing Cammy in the first half did not help.
