DAN Tomkins was the match-winner for Kings Langley as his second half header earned all three points against Crawley Green.
Sam Warrell gave Kings the lead after 10 minutes, but Robbie O’Dell restored parity before half-time.
Kevin Marsh then came to Kings’ rescue as the keeper saved O’Dell’s penalty, and Tomkins bagged the winner with 30 minutes left to play.
Kings made six changes to the side which had beaten Sawbridgeworth Town in the Herts Charity Shield on Tuesday, and initially struggled to find their flow.
Kevin Marsh and Gary Clark were both making their returns to the club after two years, and the latter had a big part to play in the Kings opener.
Clark combined well with Tomkins, and his inviting cross was nodded in at the far post by Warrell.
Crawley Green equalised when O’Dell equalised on a misjudged back-pass, and could have gone ahead one minute after the interval had it not been for Marsh’s fine save from O’Dell’s spot-kick.
That let-off inspired Kings, and Tomkins earned all three points for his side as he glanced home Clark’s inswinging corner.
