Varun Chopra and Darren Maddy tormented Worcestershire Royals again by leading Warwickshire Bears to an eight-wicket win in the Friends Life t20 West Midlands derby at Edgbaston.
The pair followed up their club-record partnership for any wicket in the competition, of 119, at New Road two weeks ago with one of 107 to keep the Bears in the hunt for a quarter-final place.
Chopra, Warwickshire's acting captain, topped his previous competition-best of 65 made at New Road with an unbeaten 75 and Maddy followed his unbeaten 84 at Worcester with 44 from 35 balls.
Worcestershire failed to capitalise on their best start to an innings in this season's competition.
The aggressive Moeen Ali and Thilan Samaraweera added 60 in seven overs from the top of the order, but the visitors were expertly reined in by New Zealand off-spinner Jeetan Patel and seamer Steffan Piolet, and restricted to 145 for eight on a good batting pitch.
Moeen showed his attacking intentions from the start by whipping off-spinner Ateeq Javid for two leg-side sixes in the first over of the match.
He survived a difficult chance to Will Porterfield at extra-cover off Patel yet failed to capitalise, falling later in the same over when top-edging a pull which allowed the fielder to atone for his earlier lapse.
Former Sri Lanka batsman Samaraweera also failed to turn his solid start into a more substantial score and was bowled off stump for 33 driving at a full-length ball from Piolet.
Only Alexei Kervezee, whose workmanlike 27 came from 28 balls, threatened to break the shackles imposed by Patel and Piolet.
But England international Chris Woakes snuffed out further resistance by taking a season's best 3-28, including Ben Cox, lbw sweeping, and Joe Leach, bowled middle stump heaving across the line, in an accurate final over.
Worcestershire made an early breakthrough when Andre Russell bowled Porterfield with a beauty but Chopra and Maddy took control in front of a 12,000 crowd before the latter was caught behind driving at Russell.
Chopra, who struck six fours and three sixes from 57 balls, and Rikki Clarke both hit leg-side maximums off Gareth Andrew to accelerate Warwickshire to victory with 15 balls to spare.
