Barnstaple AAC caused a surprise on the opening weekend of the North Devon League season with a 2-1 win against Torridgeside, the Premier Division champions.
Torridgeside lost just one game on their way to the title last year but second-half goals from Giles Daniel and Craig Sandle ensured they were beaten at home for the first time since March 2012.
Rob Holland, paired up front with new signing Charlie Tubb, bundled in the opening goal at a corner to put the champions ahead.
But a new-look Ammies team, managed for the first time by Darren Hollyoak, responded with a fine second-half display.
Daniel, the former Boca Seniors forward, claimed the equaliser with a powerful header and Sandle slid home the winner following a sharp turn and a clever pass from James Hawkins.
Hollyoak said: "We are aiming to be in the top six and if we play like that we've got every chance."
After losing a number of players over the summer, Torridgeside will find it difficult to retain their title.
Barry Paine, the manager, said: "Bideford and Braunton are going to be the favourites. We are just going to be rebuilding now. We have got some good youngsters coming through.
"I'm disappointed we haven't got a result but there were more positives than negatives."
Down the road at Vicarage Field, Torrington were beaten 4-0 by Bideford reserves on their first game back in the top flight.
Bideford only missed out on the title by goal difference last year and they look determined to go one better after a dominant performance.
Nathan Bate drilled the opening goal past Aaron Dymond and Nick Glover, the new signing from Appledore, turned in a cross from Tom Hayne to make it 2-0 by half time.
Two stunning strikes from Aaron Stevens from outside the area put the seal on an impressive display.
Boca Seniors have seen many of their best players leave over the summer but one of their most reliable match winners is still there. Matt Deakin fired a hat-trick to put the Barnstaple club 3-0 ahead against Chittlehampton.
And Darren Floyde, the new signing, scored twice after stepping off the bench to complete a 5-0 victory which put Boca top of the early table.
A new-look North Molton also responded with a win and a clean sheet after a host of departures from their first-team squad during pre-season.
With James Tapp taking charge as player-manager for the first time, the Stags beat Georgeham and Croyde 3-0 with goals from Jamie Giffard (two) and Andrew Alexander.
A last-minute equaliser from Josh Phillips gave Fremington a point on their first game in the Premier Division for 13 years.
They trailed against Appledore as Hallum Cook pounced on a mistake from Jamie Pow, the goalkeeper, just before half time.
Phillips, the defender, went forward to meet a free kick from Mark Sanders and seal a 1-1 draw with a header.
Elsewhere, Braunton beat Bradworthy 3-0, Shebbear United and Ilfracombe Town shared a goalless draw and Dolton drew 1-1 with Shamwickshire Rovers.
