Shrewsbury Town saw their Millennium Stadium dreams dashed, as Carlisle United held on to the 1-0 lead they established at Brunton Park seven days ago, to secure an LDV Trophy Final place against Bristol City on Sunday April 6.
An unbearably tense second leg ended goalless, so the Cumbrians progress to Cardiff by virtue of Adam Rundle's first-half winner at Carlisle last Tuesday.
Shrewsbury tried everything to break down Carlisle's stubborn resistance and when they did manage to create an opening found United keeper Matt Glennon in excellent form.
He produced a superb diving save from Shrews striker Luke Rodgers after 63 minutes - the pick of some fine stops as Shrewsbury were kept at bay.
The home side's dominance was underlined by the fact that Shrewsbury goalkeeper Ian Dunbavin did not have a save to make in the entire 90 minutes, not that the 1,000 strong travelling Carlisle support were bothered as they celebrated wildly at the final whistle.
