Danish Kaneria and Mark Pettini were on the winning side
Rob Key said his Kent side had "batted appallingly" after Essex beat their southern rivals by five wickets in a tense Friends Provident Trophy final.
Key went on: "We needed 30, 40 or 50 more with the bat. In the Twenty20 final we put up a good show but today our batting let us down."
Essex's man of the match was Grant Flower, who hit an unbeaten 70 as Essex recovered from 93-4 to chase down 215.
Flower said: "Chasing a small total you just hang in, get a partnership going."
The veteran Zimbabwean used his oceans of experience to time the chase perfectly after England stars Ravi Bopara and Alastair Cook had fallen in quick succession to Kent's surprise package with the ball, Robbie Joseph.
Key said of Joseph: "Serious credit to him, he's a star of the future."
But he was less pleased with his batsmen, after only one of the top seven - Martin van Jaarsveld who hit 58 - reached 20.
"There's no point getting to finals if you're not going to win them," he said.
"We batted appallingly today. Not many of us can say we were got out, we played poor shots and got ourselves into trouble."
Essex, who had lost to Kent in the Twenty20 semi-finals - a result which denied them a lucrative spot in the Champions League - could reflect on a job well done.
James Foster, who was again superb with the gloves before putting on a vital 68 with Flower, said: "We're going to celebrate and have a really good night.
"There was a fair bit of pressure out there when we were chasing and there was a little moment wehen we lost a few wickets in a cluster.
"Myself and Grant managed to get a partnership together. Unfortunately I got out at a disappointing time for me and the team but Ryan ten Doeschate [30 not out off 29 balls] played a hell of a knock and Grant Flower has been a superstar."
