The other teams to make it through on the final day of group matches in the Friends Life t20 were Worcestershire, Gloucestershire and Nottinghamshire, with Yorkshire, Sussex and Hampshire joining them in the last eight.
As the Friends Life t20 programme moves towards the end of the group stage, the 'Stand up for Friends Life t20' tour - led by Rory Bremner is also heading to its conclusion.

Lancashire will be left cursing Messrs Duckworth and Lewis after the rain meant that Nottinghamshire were set a rather generous 49 to win from five overs at Trent Bridge after the visitors had posted an impressive 178 for four from their 20 overs.
Northamptonshire thrashed Glamorgan in the Midlands/West/Wales basement battle clash at Cardiff. The visitors' spin pairing of Con de Lange and James Middlebrook returned combined figures of six for 31 from eight overs as they strangled the middle-order.
Hampshire continued their fine recent form with a seven-wicket demolition of an apparently distracted Surrey at Southampton. The Lions made just 94 for six from their 20 overs after electing to bat, with Gareth Batty once again skippering the side.
Nottinghamshire comfortably dispatched Durham at Trent Bridge to stay second in the North Group of the Friends Life t20. The Outlaws posted a formidable 210 for three from their 20 overs after choosing to bat, with England hero Alex Hales hitting 88 from only 51 balls and sharing a second-wicket partnership worth 142 with Riki Wessels.
Will Beer played a gem of an innings to help Sussex beat Essex at Chelmsford. He struck 12 from only five balls and led the way as the Sharks comfortably got the 10 runs they needed off the last over. The win means they remain top of the South Group after six games, with Essex four points behind in second.
On a day when all 18 counties were in action for the first time in this season's Friends Life t20 competition, there were wins for Leicestershire, Somerset, Gloucestershire, Essex, Sussex, Yorkshire, Warwickshire and Kent.

A brilliant eighth-wicket stand between Steven Crook and Ollie Rayner was not quite enough to help Middlesex to a famous victory under the Lord's floodlights. The Panthers had slipped to 88 for seven in the 15th over in pursuit of Essex's 155 for six, as Tim Phillips made the most of some questionable shots from the home sideâ€™s batsmen to take three for 27.
