Borthwick and Onions star in Durham win
Durham 465 and 102 for 2 beat Warwickshire 429 and 137 by eight wickets
Scott Borthwick steered Durham to an eight-wicket win against Warwickshire in County Championship Division One at Chester-le-Street. He completed a four-wicket haul for the first time in the championship and made an unbeaten 48 when sent in to open in the absence of Michael Di Venuto with a thigh strain.
Graham Onions took four of Warwickshire's six remaining wickets as they were dismissed for 137, leaving Durham to score 102 to win.
After winning their first two matches to stand joint top of the table, this was a chastening defeat for the visitors, especially after scoring 429 in their first innings.
A draw looked certain when they were 45 for one, nine runs in front, with eight overs remaining on the third day. But two wickets in Borthwick's first five balls began their collapse and he finished with 4 for 25. With the bounce becoming more variable on the fourth day, Onions skidded one through to have Rikki Clarke lbw just as Durham's first rain of the season arrived at 11.20.
Warwickshire were then 67 for 5 and after a 45-minute break it quickly became 69 for 7. Jim Troughton edged Onions to wicketkeeper Michael Richardson when trying to withdraw his bat then Borthwick's googly had nightwatchman Paul Best lbw.
Tim Ambrose and Chris Woakes put on 24 before Ruel Brathwaite replaced Borthwick and removed Woakes' off stump with a shooter. Boyd Rankin then repeated his stubborn effort of the first innings as Ambrose continued to play fluently.
He cut Brathwaite fiercely for four to reach 50 and the stand was worth 43 when he played across a full-length ball from Onions and became the fifth lbw victim of the innings. Onions ended the innings by forcing Rankin to fend to gully, where Callum Thorp dived forward to take the catch.
When Durham batted they had 28 on the board before Will Smith fell for nine, very well caught by a diving Ian Westwood at deep square leg. Gordon Muchall and Borthwick both survived good lbw appeals, while Borthwick enjoyed a little luck when he skied a top-edged pull off Rankin over the wicketkeeper.
Only 19 were needed when Muchall departed for 30, skying a straight drive off left-arm spinner Paul Best to be caught by Jim Troughton, running round from long-off. Ben Stokes helped Borthwick complete the task as Durham knocked off the runs in 25.4 overs.
