King's Lynn Town continued their superb away form by breezing past a potentially tricky derby test at a sodden Sir Halley Steward Field.

The Linnets ran out comfortable winners with goals from Danny Beaumont, Jack Defty, Danny White and substitute Robbie Harris to stay hot on the trail of UCL leaders Peterborough Northern Star.

Lynn boss Gary Setchell made one change from the side which thrashed St Ives 5-1 on Saturday, Stephen Spriggs dropping to the bench to be replaced by White.

After the kind of frenetic start expected of a local derby, Town took the lead on 21 minutes after a stunning run and cross from Jordan Yung was converted by Beaumont.

The visitors dominated large periods of the first half, with former Spalding midfielder Hughes dictating play in the centre of the park. It was soon 2-0 as talismanic striker Defty's trademark header doubled the advantage on 28 minutes, which was no more than the Linnets deserved.

The link-up play between Lynn's front six was too much for Spalding to handle while Ross Watson and Dan Bulliman remained solid at the back.

The hosts were not going down without a big effort in front of their biggest crowd of the season, however, and Lynn keeper Alex Street had to be alert to stop Ryan O'Loughlin's drive.

Former Linnet Glen Fuff also wasted a good chance for Spalding when he blazed over from deep inside the box and the home side also started the second half strongly – Simon Mowbray testing Streete within the first two minutes.

Then the Linnets took over, twice going close through Defty and Watson before Jamie Thurlborne teased John Paul Duncliffe and centred for White to head superbly into the top corner.

Just as in the first half, Lynn enjoyed the lion's share of possession while remaining patient and waiting for the openings to come.

Substitute Harris got his name on the scoresheet with five minutes remaining, having been set up by fellow substitute Spriggs, rounding off a superb away performance from the Linnets, for whom Rob Hughes deserved a mention for a faultless performance back on Spalding territory.
