Mark Pettini and Ravi Bopara excelled with the bat to help blast Essex to a 65-run victory over Somerset in their Friends Life t20 South Group encounter at Bath.
Essex captain Pettini made 81 from 52 balls, with eight fours and three sixes, and Bopara chipped in with 72 from 42 deliveries - with eight fours and a six - as the visitors rattled up 209-5.
Tim Phillips then claimed 4-22 and Ryan ten Doeschate 3-18 as Somerset were bowled out for 144 with three balls remaining.
It was Essex's second win in three days and Pettini's men are now level on 14 points their opponents who lost their second match on the trot.
After winning the toss and opting to bat, Essex raced along to 56-2 off the six powerplay overs - Adam Wheater the first man to go when he pulled leg-spinner Max Waller's first ball to Kieron Pollard at midwicket, while Tim Southee departed after he skied a slower delivery from Pollard to Lewis Gregory at mid-off.
Owais Shah fell in the seventh over for nine when he gave the charge to slow left-armer Arul Suppiah and was bowled, but Pettini and Bopara then began to open their shoulders.
All three of Pettini's sixes came after he had reached a 42-ball half-century - the first was pulled off Pollard and the next two were straight-driven off Murali Kartik, although the spinner took his revenge when the Essex captain fell to a diving catch by Peter Trego at long-off.
Bopara carried on the assault and brought up his 35-ball half-century in the 19th over. He then smashed Pollard for six over midwicket in the last over before he was run out by James Hildreth's throw from the deep with one ball left.
Somerset's reply got off to a bad start as Phillips' off-spin accounted for skipper Marcus Trescothick - who was clean bowled - and Craig Meschede - caught at long-off - with only 12 runs on the board.
David Masters had Trego caught at mid-on and it became 68-5 after Ryan ten Doeschate dismissed Hildreth and Jos Buttler in his first over.
Hildreth holed out to Pettini at long-on, while Buttler, whose 31 came from just 16 balls, skied a drive to Tom Craddock at deep cover.
West Indies star Pollard smashed 21 from 12 balls, but Somerset hopes were all but ended when he played across a ball from Masters and was adjudged lbw.
Phillips returned to have Suppiah caught at midwicket and Lewis Gregory stumped. Then, after Waller had been caught and bowled by ten Doeschate, the innings concluded when Kirby was yorked by Southee.
