A RARE goal from Simon Ovey settled the derby between Boca Seniors and Barnstaple AAC.
Boca edged through in the Graddon Vending Devon Premier Cup with a 1-0 win, setting up a trip to Teignmouth in the second round.
Ovey, the defender, went forward to head the decisive goal at a corner midway through the first half.
And despite having plenty of pressure after the break, the Ammies were unable to force an equaliser past goalkeeper Darren Babb.
It was their second 1-0 defeat to their local rivals in a month and the two sides will meet again in the North Devon League Premier Division on Saturday.
Appledore joined Boca in the second round after a 6-0 victory over Chittlehampton, with Adam Copp scoring a hat-trick. Greg Holland got two and Keith Shapland volleyed the sixth from a cross by Sam Fishwick.
Torridgeside were the only other North Devon team to go through – and they did it without kicking a ball. Seaton Town's failure to raise a team means Torridgeside walked through to a second-round clash with Tiverton Town reserves.
A woeful defensive display saw Holsworthy crash out in a 7-6 defeat to lower-league opposition.
Despite arriving at Upcott Field with only 11 players, Tavistock reserves triumphed after extra time with five goals from Jack Crago and two for Nathan Ewing.
Nick Aplin (two), Jack Hayman (two), Dean Chidley and Max Webb scored for Holsworthy who missed several golden chances and were grateful to keeper Jack Dixon for keeping them in the tie.
Braunton let a 2-0 lead slip in a 3-2 defeat against Plymstock United.
They were unhappy when the Plymstock keeper escaped with a yellow card for bringing down Simon Townsend but Ross Maynard made amends, firing the opening goal from the free kick.
Townsend doubled the lead before Plymstock took advantage of a Braunton defence in unusually generous mood.
Crediton United needed an 89th-minute winner to see off Torrington. Dan Wilson, firing through a crowded area, put Torrie ahead and they almost got a second goal when Danny Jenkins hit a post. Nathan Delaune was denied by the Crediton goalkeeper whose side edged a 2-1 win.
There was late disappointment for Georgeham and Croyde at the University of Plymouth where the students won 3-2 with a last-minute penalty. Ben Holmes and Simon Benham-Clarke scored for Georgeham.
After knocking out Bradworthy in the preliminary round, Watcombe Wanderers made Shamwickshire Rovers their next North Devon victims, winning 6-3 at Pollyfield. A Matt Downing free kick made it 1-1 and Ryan West struck twice to bring Shammy back from 3-1 down, before three late goals sealed their fate.
Dolton gave it a go after falling 3-0 down at Sidmouth Town but were beaten 4-1. Steve Orme pulled the goal back and Pierce Brant and Richie Bright impressed in midfield.
Bideford did not get to grips with the tight pitch and blustery conditions at Hideaway Café in Plymstock where Will Nicholls scored an equaliser but two late goals brought a 3-1 win for the home side.
Teignmouth brushed aside Fremington 5-1. Fremmy were 2-0 down after 20 minutes before Trevor May gave them hope with his first goal since signing from Northam Lions. The visitors were denied a bigger winning margin by a penalty save from Jamie Pow.
North Molton, still without a regular goalkeeper, were beaten 4-1 at Heavitree United where Nick Jones got his first goal of the season.
Shebbear United lost 5-0 at home to Buckland Athletic.
