Clydesdale Bank 40 (at Edgbaston): Derbyshire 122 v Warwickshire 125-1 (W T S Porterfield 81 no)
Warwickshire beat Derbyshire by 9 wkts
Jonathan Trott made an unbeaten 41 in his last innings before returning to England duty as Warwickshire registered their second Clydesdale Bank 40 win of the season in quick time against Derbyshire at Edgbaston.
Former Falcons captain Rikki Clarke took three wickets and held two catches in his old county's demise for a lightweight 122 and Trott led Warwickshire to a nine-wicket wicket victory with 15.3 overs to spare.
While the England batsman took no risks in his build-up to the Lord's Test against West Indies on Thursday, his innings was played in the shadow of William Porterfield, who struck 10 fours and a six in making 81 not out from 80 balls.
With their partnership up and running in the opening over after Varun Chopra's second-ball dismissal by Tim Groenewald, the second-wicket pair had put on 124 when Trott finished the job with successive boundaries off Chesney Hughes.
Warwickshire hit the right note from the outset as Chris Woakes took two for 20 in his first appearance since damaging ankle ligaments while fielding against Yorkshire in a pre-season T20 tournament in Barbados.
The 23-year-old all-rounder immediately slipped into a good rhythm, claiming a wicket with his 10th delivery when Derbyshire dangerman Martin Guptill was lbw for three - a week after beginning his CB40 campaign with 125 against the Unicorns.
Clarke made his initial contributions by holding a couple of slip catches, the first from Hughes in Chris Wright's opening over and then to give Woakes another key wicket when Derbyshire captain Wayne Madsen went for a duck.
Only Wes Durston - another century-maker against the Unicorns - made significant progress with 44 from 54 balls as Derbyshire lost half their side for 82.
Taking advantage when Wright dropped sort of a length, he rattled the roof of the Hollies Stand, but Clarke struck with his first ball when Dan Redfern failed to clear Darren Maddy at deep square leg.
Redfern's innings included a bizarre sequence in which Warwickshire held catches off successive deliveries - but without taking a wicket.
Redfern planted a no-ball from Keith Barker to Jeetan Patel at deep mid-wicket and, with the batsman crossing before the free hit, Durston drilled the next ball to Jim Troughton at mid-off.
After hitting five fours and two sixes, Durston eventually made a tame exit as Troughton pulled down a head-high chance at mid-off for the first of three wickets for New Zealand off spinner Patel.
With Clarke accounting for Ross Whiteley (20) and Jon Clare (0) in quick succession, Derbyshire failed to go beyond the 32nd over despite some late hitting by David Wainwright (16) and Groenewald (13 not out).
