Derbyshire 286 (Redfern 110) and 314 for 3 dec. (Guptill 137) beat Northamptonshire 264 and 134 (Wainwright 6-33) by 202 runs
David Wainwright marked his debut with a career-best match-winning performance to take Derbyshire to a crushing 202-run victory over Northamptonshire at Derby. Wainwright, the former Yorkshire left-arm spinner, found turn and bounce on a fourth day Racecourse pitch to take 6 for 33 from an unbroken spell of 26 overs as the visitors were all out for 134 after Derbyshire had set them 337 to win from a minimum of 72 overs.
Any chance they had of chasing down that target quickly vanished when they slipped to 41 for 3 and Wainwright put Derbyshire well on the road to victory when he struck twice in eight balls before tea. James Middlebrook and Chaminda Vaas dug in for 15 overs but Wainwright removed them both and the end came 35 minutes before the close when Wes Durston bowled Lee Daggett.
Derbyshire had been in control of the contest at the start of the day with a lead of 235, and the opening pair took their stand to 224 before Martin Guptill skied a pull to deep square leg and was caught for 137 which included a six and 13 fours.
The only disappointment for the home side was that Paul Borrington failed to reach a maiden Championship hundred when he fenced at Daggett and edged to slip two runs short of the mark, but his 272-ball innings had been a big factor in putting Derbyshire into a winning position.
Dan Redfern and Durston added quick runs before the declaration came at 314 for 3 and the morning session ended with a big wicket when Northamptonshire opener Stephen Peters was lbw to Mark Footitt off the last ball before lunch. Kyle Coetzer was taken at the second attempt at third slip off Tony Palladino and the rest of the day belonged to Wainwright, who bowled with guile and accuracy to snare his victims.
After David Sales perished going half forward, Rob Newton, who made 58, and Alex Wakely looked to be steering Northamptonshire towards calmer waters but they both fell either side of tea after surviving 20 overs.
The only threat to Derbyshire were the dark clouds gathering over the ground but the rain held off and the floodlights meant the visitors could not rely on bad light to save them. Luck was also against them when Middlebrook's firm drive hit Redfern at silly point and ricocheted to Footitt at backward point and David Willey became Wainwright's sixth victim when he was lbw playing no shot.
Durston had the last word when he beat Daggett's forward lunge to spark off wild celebrations among the Derbyshire fielders, who had launched their season with the county's second biggest win over Northamptonshire.
