Two firsts for Bideford resulted in a 1-0 home win over sixth-placed St Albans City and edged Sean Joyce's Robins out of the Evo-Stik League Southern Premier Division bottom two.
Defender Rob Farkins headed his first goal of the season and goalkeeper Paul Hider kept Bideford's first clean-sheet since the Robins gained promotion.
A second Saturday home win in a row – sandwiching a 5-3 defeat at St Neots Town and a 2-1 loss to Chippenham Town – lifts Bideford to third from bottom, a point above Hitchin Town and level on 14 points with Banbury United and Gosport Borough.
Next week Bideford will be hoping for more success at the Sports Ground when they host Cambridge City, 1-0 winners at Weymouth on Saturday.
Tiverton Town soared to the Division One South and West summit following their fourth win in a six-match unbeaten run, 2-0 over Wimborne Town.
Tiverton's rise has coincided with a scoring streak for target man Joe Bushin, whose 20th-minute opener at Ladysmead on Saturday was the striker's eighth goal in six games.
Bushin pounced for his 14th goal of the season after Michael Nardiello's shot smashed off the crossbar. Harry Nodwell came close to making it 2-0 before half-time while Wimborne's Kevin Gill glanced a header just wide of the post from Micky Hubbard's corner.
Home skipper Paul Kendall headed home man-of-the-match Andy Taylor's 67th minute corner to put Mark Saunders' side 2-0 up and on the way to victory. Tiverton top the table on goal difference from Hungerford Town, who have a match in hand.
Tiverton host Paulton Rovers tomorrow in the Red Insure League Cup while the Division One South and West's match of the season so far takes place next Saturday, when Hungerford host Tiverton. Hungerford will be anxious to bounce back following a shock 4-2 defeat at basement side Yate Town.
Taunton Town got back on track with a 3-2 derby win over Clevedon Town after taking a 3-0 lead at Wordsworth Drive.
Winger Jamie Short got the Peacocks off to a flying start with his fifth-minute opener. Skipper Simon Ingram tucked away a 20th-minute penalty following a foul on Rodney Marsh, who made it 3-0 four minutes later.
Toolstation Western League sides Willand Rovers, who lost 4-3 after extra time at Horndean, and Buckland Athletic, who went down 5-2 at home to Downton, saw their interest in the FA Carlsberg Vase come to an end in Saturday's second-round ties.
