Surrey kept alive their hopes of retaining the Clydesdale Bank 40 trophy with a convincing 93-run victory over the Welsh Dragons at The Oval.
The game, which was dedicated to the memory of Tom Maynard, was dominated by the home side, who posted 219-9 thanks to responsible knocks from Matthew Spriegel (51) and Kevin Pietersen (43).
In reply, the Welshmen collapsed from 55-2 to 77-8, with Gareth Batty taking three wickets for four runs, before eventually being skittled out for 126.
The match was played on a sombre backdrop as both sets of players recognised their former player Maynard, who died in June after being hit by a London Underground train.
The match marked the official launch of the Tom Maynard Trust and before play a posthumous county cap was awarded to his father, Matthew, by Surrey chairman Richard Thompson.
After winning the toss and opting to bat, Surrey initially raced along at more than seven an over, but were forced to adopt a more circumspect approach as Steven Davies (five), Rory Hamilton-Brown (28) and Jason Roy (six) were all removed early on.
Pietersen, who cut his first ball for four, played watchfully but with authority and found a useful ally in Spriegel.
Jones wins KP duel
Simon Jones won his duel with his former Ashes team-mate when he sent Pietersen's off stump cartwheeling, but a sixth-wicket stand of 54 in 10 overs between Spriegel and Zafar Ansari helped Surrey build a solid platform.
Ansari was eventually bowled by Allenby for 30, but some late hitting from Spriegel and Stuart Meaker (21 not out) saw the hosts past 200.
In reply, the Dragons overcame the early loss of Mark Wallace and Jim Allenby to be 50-2 after 10 overs.
Chris Cooke made a bright 31, adding 45 in tandem with Gareth Rees, but was run out in the 12th over, trying to steal a leg bye to Pietersen at short third man and that led to a clatter of wickets.
Two overs later, Gareth Rees reverse swept Kartik to point, Stewart Walters played around a turning delivery from Gareth Batty, Ben Wright fell to a superb catch by Ansari at square leg and Marcus North played on to leave the visitors in deep trouble.
James Harris was caught down the leg side off Jade Dernbach to make it 77-8 and, while Cosker and Wagg hit straight sixes off Dernbach and Ansari, it was too little, too late.
