Warwickshire 135 (C D Thorp 5-49) & 238 (J O Troughton 111) v Durham 273 (D M Benkenstein 73, I D Blackwell 53, W B Rankin 5-85) & 106-2.
Durham (19pts) beat Warwickshire (3pts) by 8 wkts
Durham claimed their seventh County Championship win of the season with a comfortable victory over Warwickshire at Chester-le-Street on Friday.
Needing 101 to win after bowling out Warwickshire for 238, the hosts completed the task for the loss of just two wickets to extend their lead at the top of the table past 40 points.
Shivnarine Chanderpaul and Michael Di Venuto both remained unbeaten on 41at the close after Durham lost Mark Stoneman (5) and Will Smith (11) to edged catches.
Warwickshire started the day well, with Rikki Clarke and Jim Troughton surviving the first half hour before a 30-minute rain break.
But, in the second over after the resumption of play, Clarke went down to a good catch by Callum Thorp at deep mid-off as he tried to lift Ian Blackwell to long on.
Troughton brought up his century just after lunch before handing Di Venuto a catch off Ian Blackwell while on 111.
His wicket precipitated a late-order collapse that saw the last five Bears wickets fall for the addition of just 37 runs.
In reply Chanderpaul, who scored a duck in the first innings, got off to a shaky start and almost played on to Chris Woakes on just 19.
But the West Indian found his form when Rikki Clarke replaced Sri Sreesanth, pulling and cutting his first two balls for four.
Clarke's two overs cost 21 as Chanderpau let loose and finished the job with a six over long-on off the left-arm spin of Ant Botha.
A half-century by Jim Troughton helped stem the prospect of a two-day defeat for Warwickshire in their match against leaders Durham in Chester-le-Street.
After the home side had made 273, the visitors found themselves struggling on 34-3, still 104 runs behind.
Captain Ian Westwood departed in the third over, fending Mitch Claydon to Liam Plunkett at gully before Ant Botha edged Callum Thorp to Phil Mustard.
Tony Frost was then caught by Thorp off Claydon at third slip but Troughton was then joined by Tim Ambrose and the pair put on 82 in 19 overs.
Ian Blackwell had Ambrose (39) caught at slip, but Warwickshire were only 11 behind at the close on 127-4.
Durham, without Graham Onions who was not released by England despite not being selected for the fifth Ashes Test, had earlier added 100 runs to their overnight total after rain delayed the start.
Further showers interrupted play but Blackwell completed a 59-ball half-century before edging Naqqash Tahir to Ambrose.
Dale Benkenstein made 73 before edging a good ball from Boyd Rankin to second slip while Phil Mustard (25) was brilliantly caught by Troughton above his head at backward point.
Thorp edged into his stumps while Plunkett (31) was helped by Claydon and Mark Davies to add 40 for the last two wickets.
After conceding almost six runs an over on the opening day, Rankin completed his first five-wicket haul in the Championship.
Division One leaders Durham continued their dominance by dismissing Warwickshire for 135 with Callum Thorp taking his second five wicket haul in as many home games.
Dale Benkenstein took three wickets and then made 59 not out as the hosts passed their opponents' total to reach 173 for four at stumps.
Durham can expect either Steve Harmison or Graham Onions to join up when England name their side for the fifth Test but neither was required in the first innings as Thorp took the honours.
Mark Davies took the new ball but suffered a back spasm after bowling just two overs, allowing Thorp to rip out the top order.
He swung the ball sharply back into the three left-handers at the top of the batting, which lacked the England pair Ian Bell and Jonathan Trott, earning lbw decisions to remove Ian Westwood and Jim Troughton.
Ant Botha and Tony Frost took the score to 70 for two before Benkenstein struck with his gentle swingers, accounting for Botha, who chipped a catch to mid-wicket, and Tim Ambrose for a duck.
Seventy for four at lunch became 71 for five when Benkenstein had Frost caught behind attempting to cut, giving him figures of three for four at the time.
Thorp also had 17-year-old debutant Ateeq Javid lbw for eight while Rikki Clarke fell in similar fashion having made a top score of 32.
Sreesanth slogged a catch to mid-on to give Thorp his fifth wicket but suffered a buttock strain that meant he was unable to take the new ball.
Michael Di Venuto hit Boyd Rankin's first three balls of Durham's innings for four and went on to make 40 from 35 balls before Naqqash Tahir had him caught behind with the score on 43.
Mark Stoneman had scored the other three off 23 balls before Chris Woakes induced an edge without addition to the total, and Rankin accounted for Will Smith for 16.
Shivarnine Chanderpaul, making his first appearance of the season, failed to trouble the scorers but Benkenstein struck 10 fours in his 68-ball half-century and Ian Blackwell made 48 not out from 54 deliveries to put Durham firmly in the driving seat.
