Surrey were shot out for their lowest ever Twenty20 total as they crashed to a 70-run defeat against Essex in the South Division at Chelmsford.
Replying to a total of 164 for nine, they could only respond with 94 all out, their last eight wickets crashing for 41 in the space of eight overs.
They simply had no reply to tight bowling backed up by superb work in the field.
Pakistan leg-spinner Danish Kaneria conceded just five runs in his three overs, his two successes - those of Alistair Brown and Abdul Razzaq, coming in his first over.
That paved the way for Ryan ten Doeschate to scythe through the rest of the batting as he went on to claim four for 24, his best figures in the competition.
That completed a great night for the 28-year-old all-rounder because earlier he had revived Essex with a swashbuckling partnership with James Foster. Coming together at the fall of the fourth wicket in the 13th over with only 74 on the board, they plundered 64 from only 28 deliveries, helping themselves to five sixes and three fours in the process.
Ten Doeschate struck 35 from only 16 balls while Foster's 41 spanned just 23 deliveries.
It was a blitz to which Surrey had no reply. Their innings got off to the worst possible start when Scott Newman fell lbw to the first delivery sent down by paceman Graham Napier.
Napier soon followed that up by gaining a similar verdict against Mark Ramprakash, before Kaneria's double strike virtually put an end to Surrey's hopes.
This was Essex's third successive victory and they now share joint second spot with Kent, who they meet at Beckenham on Sunday.
They are two points behind leaders Middlesex in what is becoming a fiercely-contested battle to top the South Division.
Meanwhile, Surrey are left at the bottom of the table, having lost five of their six games to date.
