Warwickshire assured themselves of a place in the quarter-finals with a four-wicket victory against Somerset at Edgbaston. Jim Troughton hit a Twenty20-best 57 as the home side paced the pursuit perfectly with Ant Botha and Michael Powell completed the job. The end, though, included some confusion as a scoreboard malfunction meant the umpires had to consult the scorers to get the exact requirements. Warwickshire actually conceded their highest total of the season, but Somerset would have been eyeing even more than 173 when Justin Langer and Marcus Trescothick gave them a flying start. However, Both and Ian Salisbury produced tight spells of spin as Somerset fell away to 107 for 6. Arul Suppiah and Omari Banks hit hard at the end, yet Warwickshire had enough in the tank to get home.

Glamorgan suffered a blow to their qualification hopes, going down to a comprehensive seven-wicket defeat against Gloucestershire at Bristol. William Porterfield, who has opted for his county over his country, guided the chase with 62 off 57 balls. Glamorgan struggled for momentum early in their innings against an impressive spell from the on-loan AJ Harris. He removed Robert Croft and, vitally, Herschelle Gibbs for 3. The middle order tried to rebuild, but couldn't score at a quick enough rate as Ian Fisher claimed three economical wickets.

Worcestershire registered just their second victory of the season with a four-wicket win against Northamptonshire at New Road. They crossed the line with seven balls to spare as Steven Davies hit 23 off nine balls alongside Moeen Ali. Stephen Moore anchored the early part of the chase with 51 off 36 balls. Northamptonshire's in-form batting order staggered to 31 for 3 against Chris Whelan and Kabir Ali before slumping again to 94 for 6. Andrew Hall led a fight back with 58 off 51 deliveries, adding 55 with his former South Africa team-mate Lance Klusener, who biffed 41 off 21 balls. It gave them something to bowl at but, for once, Hall had an poor day in the field as he conceded 47 runs off 3.5 overs.

Jeremy Snape ended his professional career on a winning note as Leicestershire final broke their Twenty20 duck for the season with a five-run victory against Nottinghamshire at Grace Road. Snape played his part at the end with two tight overs and the vital wicket of Adam Voges (59), as the visitors watched their quarter-final hopes take a blow. However, the real matchwinner was Jim Allenby who claimed three late wickets to follow an unbeaten 57. Voges was keeping Nottinghamshire's hopes alive after Nadeem Malik took 4 for 16, but fell with 12 needed. Allenby steadied Leicestershire from 11 for 3 along with Paul Nixon who hit 42.

Durham moved to within touching distance of the quarter-finals after blowing away the Yorkshire top order at Chester-le-Street. The eventual margin was 39 runs on the D/L method after rain ended the match 10 overs early. Shaun Pollock, Liam Plunkett and Steve Harmison all impressed, with Harmison especially tough to face in the fading light. Michael Vaughan missed the match after being ordered to rest by England and Yorkshire now need to win both their last two matches to have any chance of progressing. The best batting of the day came from Phil Mustard, who clubbed 49 off 37 balls in Durham's 162.

Middlesex bounced back from back-to-back defeats with a tense six-run victory against Kent at Uxbridge. Tyron Henderson showed his expertise at the death as he prevented the hard-hitting Azhar Mahmood from hauling Kent across the line. Shaun Udal was again outstanding, claiming three top-order wickets for just 19 in his four overs including Robert Key caught at long-on for 49. Middlesex recovered from early batting wobbles through a fourth-wicket stand of 94 in 11 overs between Eoin Morgan (64) and Dawid Malan (52 not out). Malan confirmed the promise he has shown during the tournament with his 34-ball innings that included three sixes.
