|County Championship Division One, Chester-le-Street|
|Close, day one: Durham 267 v Warwickshire 31-1|
|Durham 2pts, Warwickshire 3pts|
Keith Barker finished with four wickets as Warwickshire bowled Durham out for 267 on day one at Chester-le-Street.
The medium-pacer mopped up the tail, taking the wickets of Mark Wood and Chris Rushworth to end with impressive figures of 4-41 from 19.5 overs.
Ben Stokes (61) and Will Smith (45) top-scored for the hosts, sharing 65 for the fourth-wicket.
Warwickshire had enough time to begin their reply, but closed on 31-1 when Ian Westwood fell to Graeme Onions.
After winning the toss and electing to bat, Durham lost opener Mark Stoneman to the influential Barker with only the second ball of the day.
However, the hosts' other opener Keaton Jennings (33) managed to build a platform alongside Scott Borthwick (36), before both fell when they looked well set.
Jeetan Patel (3-68) took arguably the biggest scalp of the day, having former England international Paul Collingwood caught by Varun Chopra for only one run, while Phil Mustard fell to Rikki Clarke (3-37) for a duck.
After Barker polished off the Durham tail, reigning county champions Warwickshire made strong running off their 6.3 overs before Westwood was caught by Rushworth to leave them still 236 runs in arrears at stumps.
VIEW FROM THE COMMENTARY BOX
BBC Coventry & Warwickshire's Clive Eakin:
"As long as the weather stays favourable over the next three days, the draw looks like the least likely result on this pitch. Having won the toss Durham would have wanted a bigger total, but they're probably not far short of par.
"All the bowlers caused problems with Chris Wright and Boyd Rankin both unlucky to finish wicketless. Jeetan Patel extracted first-day turn and Warwickshire won't relish chasing a target batting fourth.
"Ben Stokes' 61 was entertaining but no Durham batsman was able to apply themselves for the sort of big innings that could win a game like this."
