Nottinghamshire Outlaws held their nerve in impressive fashion to maintain their unbeaten record in the Twenty20 Cup with a nail-biting victory over Yorkshire by four runs.
In an absorbing low-scoring match, the visitors needed 12 runs off the last over - bowled by Rob Ferley.
And the left-arm spinner held off Jacques Rudolph and Andrew Gale, conceding just seven to send the crowd of 11,122 home happy.
Yorkshire were chasing a total of just 150 but only Anthony McGrath was able to master the conditions with 55 off 44 balls, and his dismissal by Ferley at the start of the 16th over proved crucial.
Earlier, Rudolph picked up three wickets for 20 runs in the Outlaws' total of 149 for nine, with Bilal Shafayat top-scoring for the hosts with 31.
Nottinghamshire won the toss and chose to bat, with Graeme Swann starting brightly by pulling Jason Gillespie for six and four.
But Gillespie struck back in his second over to bowl Swann for 17, while Yorkshire captain Darren Gough bowled his opposite number Stephen Fleming in the next over and then turned to spin to throttle the run-rate.
Samit Patel drove Richard Pyrah to long-on for 21, while Mark Wagh was bowled by the impressive slow left-arm of David Wainwright soon after.
Overseas batsman David Hussey hit Pyrah for two fours on his way to 20 before miscuing Rudolph's leg-spin to long-off, while Shafayat's innings was brought to an end by the returning Gough.
Rudolph picked up two wickets in the final over but was also hit for six by Simon Francis.
Yorkshire looked short of confidence from the off despite their low target, with two wickets falling in the first two overs.
Craig White made 27 with five fours but then offered a return catch to Swann, who combined with Gareth Clough's medium-pace as five overs went for just 16 runs.
McGrath and Rudolph were both unable to clear the ropes, with the right-handed McGrath driving Ferley to Clough at extra cover, while Chris Gilbert found the same fielder in the next over after spooning a Swann full-toss high in the air.
Ferley conceded just two runs of the first four balls of the last over, and although a full-toss was hit to the midwicket boundary by Gale, the batsman could not find the six needed off the final delivery to claim victory.
