Kent opener Joe Denly struck a quick-fire fifty as his team beat Surrey by 13 runs in the Twenty20 Cup match at The Oval.
Denly's half-century helped Kent to a total of 181 for five, and Surrey never really looked like catching them as they lost wickets at regular intervals and finished on 168 for seven.
Kent were put in to bat by Surrey, and the visitors wasted no time in building their innings, passing the 50 mark with Robert Key's four to cover in the sixth over.
Denly was finally out for 52 in the ninth over, caught at long on by Ali Brown when attempting to hit a big six off Abdul Razzaq.
Denly's impressive score came from just 33 balls, including six fours and two sixes, and his wicket signalled the end of a solid 81 opening wicket stand with Key.
Martin van Jaarsveld went for just three in the 10th over, Mark Ramprakash making a good diving catch at short mid on after the South African had mis-hit a Matthew Spriegel delivery.
But the Kent run-rate did not slow down as Justin Kemp hit two sixes and a four in the 13th over to highlight a dominant batting performance from the away side.
Key was run out on 42 in the 14th over, before Kemp scooped one to Razzaq at long on from a slower Pedro Collins delivery as Kent continued to score runs at a solid rate.
Azhar Mahmood was the last Kent casualty, as he mis-timed a shot from Razzaq straight to Ramprakash at short mid off in the 19th over.
But a brilliant final over that included two fours and a six from Darren Stevens yielded 17 runs to Kent and gave them a good total.
Surrey's reply looked good after 17 runs in the first over, but Kent's bowling and fielding were solid as they reduced the home side to just four sixes in the innings and Surrey were always behind the required rate.
The main problem for Surrey was the loss of regular wickets, James Benning the first to go, bowled by Ryan McLaren in the fifth over for 17.
McLaren claimed three wickets in the innings, adding Ramprakash and Ali Brown to his list to leave Surrey on 97 for three after 11 overs.
Scott Newman (48) and Razzaq (7) soon followed as Surrey began to run out of batsmen capable of making the runs needed.
Surrey were left needing 25 runs off the final over and Kent sealed the win.
