The South West's interest in the Johnstone's Paint Trophy shrunk from three clubs to two as Yeovil Town edged out Torquay United by the narrowest of margins.
The Gulls took the lead in the 25th minute when Ryan Jarvis slotted home following good build up play involving Danny Stevens and Billy Bodin.
Yeovil drew level on 38 minutes when James Hayter stabbed home from close range after a mistake by Torquay keeper Michael Poke.
However, Torquay restored their advantage in the 58th minute when Danny Stevens picked out Jarvis who completed his double with an angled shot.
This looked to have been enough to clinch victory for the Gulls before Hayter bagged a brace of his own when he found the target from six yards, which would send the tie straight to penalties at full-time.
Hayter, Ed Upson, Gavin Williams and Jamie McAllister all converted their spot kicks for the Glovers, whilst for the Gulls, Tom Cruise had his penalty saved by Yeovil keeper Marek Stech in the middle of Lee Mansell, Nathan Craig, Billy Bodin and substitute Rene Howe successfully converting their penalties before Keanu Marsh-Brown scored the Glovers' crucial fifth spot-kick.
Yeovil will now face Wycombe Wanderers in the Southern Area Quarter Finals and will feel confident that they can make real progress in the competition this season.
Despite the defeat, Gulls boss Martin Ling can take some positives from the defeat, namely the fact that his side were able to match League One opposition for most of the match and the fact Ryan Jarvis scored twice after coming in for leading scorer Rene Howe.
