An excellent all-round display saw Park seconds continue their good form with a dominant victory over league leaders Redbourn.
Without skipper Guy Warman, Knebworth bowled well restricting the Redbourn batsmen early on.
The home team looked to accelerate, pushing the run rate up to four an over by the 20th over but come the half-way point Park had dragged the home team back to 86-4.
Wickets continued to fall at regular intervals, pegging back any hope of a competitive total by the home team who finished on 163 all out in the final over, with Shaun Robinson (3-17) being the pick of the bowlers.
Knebworth opened up with the experienced pairing of Ryan Skeggs and Robinson.
Wary of getting bogged down chasing a small total and with the errors of the previous week fresh in their minds, the openers set off at an electric pace with 28 hit off the first two overs.
Had not been for a couple of contentious LBW decisions, the pair would have probably seen their team home; Robinson was shot away in the 14th over, with Skeggs crafting a solid 54 before succumbing to another decision.
A late flutter of wickets brought back the anxieties of the previous week but thanks to an impressive knock by Archie Stephens (40 not out) the game was finished off in style with eight overs to spare.
The Seconds lie fourth, dropping one place on run rate, having beaten two of the top three already this season.
