Will Cook struck four times during a man-of-the-match performance as Long Sutton moved level on points with Bishop’s Stortford.
Sutton started brightly with some great attacking runs down each wing from Fred Whatling and Dan Batten.
Ben Shore unselfishly slipped the ball to Josh Fyson at the back post to put them ahead.
Cook doubled the lead but Stortford pulled one back in the second half.
Shore soon restored the two-goal advantage and he was on target again after Cook’s second.
Cook completed his hat-trick then added his fourth in the dying minutes.
Spalding’s young side outplayed an experienced Long Sutton team in the first game of the Men’s County Championships on Sunday.
They passed the ball around brilliantly and attacked with real purpose and conviction in the first 20 minutes of the game with four goals from open play plus a short corner.
Long Sutton replied twice but, in the second half, four more goals were scored by Spalding to emphasise the difference between Premier B and Division One.
Spalding won 3-2 away to Waltham Forest in the league on Saturday with goals by Stuart Cunnington, Harry Vickers and Tom Everton.
