YORKSHIRE have beaten title rivals Durham inside three days at Scarborough to move ever closer to retaining the County Championship.
The visitors were bowled out for 263 shortly after tea, chasing 447 for victory, to give Yorkshire victory by 183 runs.
After Durham resumed on 107-2 after lunch, they lost their third wicket in the second over of the afternoon session when Scott Borthwick was brilliantly caught by a diving Glenn Maxwell at third slip for 31.
Plunkett took his third wicket of the innings with the score on 143 when he bounced out Gordon Muchall, who fended to wicketkeeper Andrew Hodd for 15.
Michael Richardson and Jack Burnham, the 18-year-old debutant, added 53 for the fifth wicket in 17 overs before Richardson went lbw to Tim Bresnan for 48.
Yorkshire then took two wickets on the stroke of tea, Adil Rashid having Ryan Pringle caught at mid-wicket by Gary Ballance for four, and Andrew Gale running out Jamie Harrison for a duck with a throw from cover.
