Warwickshire top of the pile
Warwickshire Bears eked out an eight-run win over Leicestershire Foxes to ensure they would reach the quarter-finals of the Friends Provident t20 as North Group winners.
They lost England batsman Jonathan Trott for two early on and they needed some middle-order hitting from Darren Maddy to bring them to 137 for seven.
Despite the modest size of the chase, the Foxes somehow failed to take the victory, managing only 129 for six as their dreadful run at Grace Road continued.
Big-hitting Steven Croft sent Lancashire Lightning into the last eight on the back of a tense seven-run win against Worcestershire Royals at New Road.
With Croft making 88 from 52 balls, Lancashire piled up 198 for six - their biggest total of the campaign - but they were stretched to the limit when Moeen Ali launched a blistering counter-attack with 72 from 39 deliveries.
Even when the left-hander was caught on the boundary off Gary Keedy after hitting eight fours and four sixes, the Royals kept up their chase until finishing tantalisingly short on 191 for seven.
Northamptonshire Steelbacks clinched the fourth quarter-final place from the North Group - Nottinghamshire Outlaws having already qualified - as they eased to a seven-wicket win at the Emirates Durham ICG.
They won with 13 balls to spare after Durham Dynamos limped to 129 for five from their 20 overs.
Northants had looked like winning by an even bigger margin when they were 121 for one with 5.1 overs left but endured a mini-wobble before closing things out.
In the South Group, Hampshire Royals’ progress in the competition was sealed by virtue of a 45-run win over already-qualified Sussex Sharks and a superior run-rate to Surrey Lions.
Hampshire went into the tie perilously perched in fourth place and needing a win to be sure of progressing.
Thanks to a powerful unbeaten knock of 67 off just 49 balls from former South Africa international Neil McKenzie, Hampshire were able to amass a competitive 195 for five from their 20 overs.
A disciplined team bowling performance then saw them restrict an out-of-sorts Sussex, who qualify in third, to 150 all out in reply.
Somerset Sabres won the group but ended the phase on a low note, bundled out for 82 - their lowest score in the competition - by Kent Spitfires at Taunton.
Replying to Kent’s 141, the home side fell apart as Simon Cook and James Tredwell took three wickets each on the normally batsmen-friendly square. Arul Suppiah top-scored with 19 not out.
Joe Denly's 65 for the Spitfires was the game's only half-century, while Darren Stevens scored 39 and later took two for 23 from his four overs.
Alfonso Thomas (3-21) enhanced his position as the competition's leading wicket-taker.
Essex Eagles also had to balance the pain of defeat with the satisfaction of going through after an 11-run reverse to Middlesex Panthers at Chelmsford.
Overcoming the loss of Neil Dexter in the opening over, Middlesex went on to total 173 for seven, with Gareth Berg (41) and Ben Scott (43no) the main contributors.
The hosts mustered 162 for six in response, never really getting over the loss of England batsmen Alastair Cook and Ravi Bopara cheaply at the top of the order.
In other action, Yorkshire Carnegie defeated Derbyshire Falcons by six wickets at Derby, with both sides going out.
The same fate befell Surrey and Gloucestershire Gladiators, with the Lions winning their match at Bristol by six wickets.
