Liam Plunkett was again Durham’s enforcer as they closed in on a fourth successive LV County Championship Division One win against Worcestershire at Chester-le-Street.
Needing 179 to triumph and stretch their lead at the top of the table, there was no hint of their calamitous start in the first innings and they reached 64 for one at the close of day three.
As in Worcestershire’s first innings, the first five wickets were shared by five bowlers before Plunkett went on to complete the first ten-wicket match haul of his career.
He added an 11th as he followed his career-best six for 63 on the first day by finishing with five for 56, but the game’s other star performer, Worcestershire’s Kabir Ali, was unable to follow suit.
After the failures of a batting line-up depleted by losing three men to England Lions, Kabir made 30 not out to go with his six for 68.
But in fresher conditions the lavish swing of the first evening, when he reduced Durham to one for three, was no longer available.
Earlier, the visitors played a huge part in their own downfall as they subsided from 59 for one to 179 all out.
The 19-year-old Dutch international Alexei Kervezee played very impressively and was largely untroubled until Plunkett came back for his second spell.
Kervezee completed his maiden championship 50 off 105 balls and had reached 66 when he shaped to hook Plunkett and top-edged a catch to Phil Mustard.
Then acting captain Gareth Batty shouldered arms to one from Plunkett which knocked out his off stump.
As Ian Blackwell found enough turn to provide Mustard with two more catches, Worcestershire collapsed to 124 for eight before Chris Whelan helped Kabir put on 45. But it was too late to repair the damage.
