Yorkshire's LV County Championship Division One survival hopes suffered a blow as they collapsed to defeat by an innings and 58 runs with a day to spare against title-chasing Warwickshire at Headingley.
The Tykes, faced with a first-innings deficit of 185, were bowled out for 127 in 37.5 overs second time around.
Chris Wright, on loan at Warwickshire from Division Two side Essex, claimed 5-31 and fellow seamer Keith Barker picked up 4-56 as the visitors sealed victory in the evening session.
Richard Pyrah's 28, made off 17 balls, was the top score of a miserable effort from Yorkshire, who will be back in the relegation zone if Worcestershire avoid defeat at Hampshire.
Earlier, Warwickshire advanced their first innings from 340-6 to 482 all out, Shivnarine Chanderpaul narrowly missing out on a double century.
The Guyanese left-hander, on 167 overnight, was caught behind off Steven Patterson's bowling for 193, which came off 306 balls and featured 26 balls.
Barker (85) and Neil Carter (40) provided useful runs lower down the order before part-time spinner Joe Root cleaned up the tail for career-best figures of 3-33.
Warwickshire's 23-point haul leaves them three points behind Division One leaders Lancashire with three games remaining.
A defiant century from Shivnarine Chanderpaul pushed Yorkshire into even deeper relegation trouble on day two of their LV= County Championship match with Warwickshire at Headingley.
The West Indian made an unbeaten 167 as Warwickshire moved on to 340-6 at stumps to establish a 43-run first innings lead.
Needing to dismiss their opponents quickly to assume control of a game they must win if they are to maintain any reasonable chance of preserving their Division One status, Yorkshire found Chanderpaul in typically stubborn mood and their survival hopes now look bleak.
Yet the morning had begun promisingly for the hosts as both of the visitors' openers were sent back with only five scored, Varun Chopra having his off-stump pegged back by Steve Patterson and Ian Westwood falling lbw to Ryan Sidebottom.
But their departures brought in Chanderpaul, playing in only his second match for Warwickshire, and the 37-year-old calmly went about building a big innings without ever looking in the least threatened.
At the other end Laurie Evans (43) and then James Troughton (27) departed to Rob Wainwright and Richard Pyrah respectively to leave Warwickshire on 115-4.
The appearance of Tim Ambrose accelerated the scoring and he carried the game further away from Yorkshire with six consecutive boundaries, four off them off Pyrah and two of them from Adil Rashid long hops.
Ambrose hurried to a 57-ball half-century which contained nine boundaries and at tea Warwickshire were a healthy 208-4 with Chanderpaul unbeaten on 87.
Wainwright, who would finish the day with 3-83, eventually accounted for Ambrose (59) after a sharp slip catch from Jacques Rudolph and the spinner also trapped Darren Maddy leg before for 12.
By that stage Chanderpaul had reached three figures and a 57th first-class century and he guided Warwickshire to a third batting bonus point aided by Keith barker who ended on 33 not out.
Yorkshire fell just three runs short of a much needed batting point as they were bowled out for 297 by Warwickshire on the opening day at Headingley.
The hosts' batting line-up were disappointing against a depleted Warwickshire attack, losing key batsmen to poor shots just as they looked to be well set.
Yorkshire made a solid start, with Jacques Rudolph the only wicket to fall in the morning session when he was trapped lbw to Barker for 24.
It was slow going though and at lunch the home side were on 95 for one, with opener Joe Sayers on 31 and Joe Root just five behind after batting fewer 15 overs.
The pair put on 80 for the second wicket but Root fell lbw for 29 and Sayers (47) followed in the next over, and from there the wickets fell steadily, poor shot selection ending a number of positive start.
Gary Ballance offered some stubborn resistance with a 103 ball 57 and David Wainwright added a breezy 32 lower down the order.
Keith Barker was the pick of the bowlers with 4-73 and left-arm spinner Chris Metters claimed 3-31.
