Patel to the fore for unbeaten Warwickshire
Jeetan Patel's four wickets helped Warwickshire make it three wins from three Clydesdale Bank 40 Group C games with a routine eight-wicket victory over Northamptonshire.
The New Zealand off-spinner returned 4-27 and Keith Barker 3-27 as the Steelbacks were bundled out for 148, with only Alex Wakely providing any resistance in making 62 off 78 balls.
The Bears were able to chase down their small target with 44 deliveries to spare as Varun Chopra made an unbeaten 87 from 117 balls.
Northants won the toss and chose to bat in the hot conditions, but lost David Willey for 24 in the eighth over when he was trapped leg before by Chris Wright.
Scotland international Kyle Coetzer then departed for 15; he launched Patel to Ireland captain William Porterfield at square-leg.
Northants skipper Andrew Hall made just five before he too picked out Porterfield, who took a difficult chance at deep midwicket.
Niall O'Brien could only reach 11 on his return to the side before being caught and bowled by Patel to become his third victim.
Opener Wakely hung around to reach 50 from 62 deliveries, but Rob White was soon heading back to the pavilion when he fell lbw to Patel.
Wakely then walked when he dragged Chris Woakes on to his stumps before James Middlebrook fell to a fantastic one-handed catch by Warwickshire captain Jim Troughton off Barker.
Darren Maddy was brought on in the 34th over and removed wicketkeeper David Murphy with his first ball, Rikki Clarke accepting the catch at midwicket.
Oliver Stone went for a six-ball duck as he was taken by Clarke off Barker before the same bowler pinned Lee Daggett lbw to end the hosts' sorry innings.
Chasing just 149, the Bears were given a let-off when Porterfield was dropped on 18 by Stone at long-on after launching Con de Lange into the air.
Porterfield plundered another 12 before Stone made amends in the 15th over, holding on at mid-on off de Lange.
That broke an opening stand of 70 with Chopra, who went on to complete a patient half-century off 80 deliveries.
Troughton came to the crease and was on 27 when he played Wakely onto his stumps, just before Chopra struck the winning two runs off Stone in the 33rd over.
