Essex all-rounder Graham Napier recorded sensational figures of 7-32, including four wickets in four balls, to help the Eagles record a resounding 178-run victory over Surrey in the Yorkshire Bank 40 at Chelmsford.
On the same ground where Napier bludgeoned 152 not out in a 20-over fixture almost five years ago, the English all-rounder treated the Essex crowd to another dazzling display, this time with the ball, to leave Surrey's run-chase in tatters.
After clean bowling Jason Roy (2) and Ricky Ponting (2) in his opening spell, Napier returned to remove Azhar Mahmood (36), Zander de Bruyn (0), Tom Newell (0) and Jon Lewis (0) in successive balls in an incredible 25th over of the reply.
The feat reduced Surrey to 113-8 in response to Essex's imposing 312-7 and from there, there was simply no way back.
Napier struck again in his next over with the wicket of Stuart Meaker to register the second best-ever List A bowling figures for any Essex player, and David Masters sealed an emphatic win with the wicket of Gary Keedy.
Earlier, Owais Shah and Ravi Bopara had led the scoring for the home side, with Shah playing a superb innings of 68 from 53 balls including three sixes and four other boundaries.
Bopara warmed up for the ICC Champions Trophy with 54 from 58 balls, with five boundaries and a six, sharing a 55-run partnership in just 27 balls alongside Shah.
There were also briskly struck contributions at the top of the order from Tom Westley and Mark Pettini, who scored 34 and 43 respectively, before James Foster added 39 from 18 deliveries at the conclusion of the innings.
