Warwickshire powered on towards the knockout stage in the Twenty20 Cup with a 38-run victory over struggling Worcestershire in front of more than 15,000 fans at Edgbaston.
Having moved alongside Northamptonshire at the top of their group on Thursday, they made it four wins in a row by making 151 for five and then dismissing their neighbours for a paltry 113.
Seamers Chris Martin, Chris Woakes and Tim Groenewald made an early breakthrough before Ian Salisbury and Ant Botha sent Worcestershire to their fourth defeat since winning their opening game against Gloucestershire.
The two spinners shared four wickets for 39 runs in seven overs and Salisbury, who did not play in the competition for Surrey last season, achieved his personal-best figures in the shortest format by taking three for 18.
The former England bowler removed the main obstacle by bowling Graeme Hick for 28 and this was the signal for Worcestershire's out-of-form middle order to fall into disarray. Kabir Ali (23) and Gareth Andrew (14) eventually put up some resistance and Simon Jones smashed a six over long-off.
After five away games on the bounce, Warwickshire preserved their unbeaten Twenty20 record despite a relatively low-key batting display.
Pinned down in the middle section by Gareth Batty (one for 24) and Daryl Mitchell (two for 19), they only squeezed past 150 after Michael Powell's unbeaten 25 from 19 balls,
Yet they had been given a typically boisterous start when Neil Carter made 27 in an opening partnership of 55 in seven overs with Jonathan Trott.
The left-handed Carter took 14 runs off Jones' first over - hoisting the England paceman over square leg for six - but not for the first time, slow bowling was his undoing as soon as Batty joined the attack.
An lbw decision was a formality when he failed to make contact, attempting to sweep the fifth ball he faced from the off-spinner, and his dismissal tipped Warwickshire into a slide to 119 for five by the 17th over.
Trott (27) lifted a ball from Mitchell to long-off and Jim Troughton hit three sixes in his 32 before Jones (one for 37) picked up a wicket when Batty held a spectacular one-handed overhead catch at long-on.
