Yorkshire complete victory at Headingley
Yorkshire completed a 95-run victory over Lancashire at Headingley on Thursday morning to leave Glen Chapple's side in grave danger of relegation.
Lancashire were bowled out for 134 in their chase of 230, within the first 40 minutes of day four.
Ben Coad finished five for 24 from 15.1 overs, while Jack Brooks added four in the innings and nine in the match.
Lancashire will be mightily frustrated at letting a position of strength in this game slip, and they have not won a Roses Championship match since 2011 - a run of eight fixtures, of which Yorkshire have won five.
At the end of day one, Lancashire were 105 without loss replying to Yorkshire’s first-innings 209. From then on, the White Rose dominated the game on the way to a fourth win from 12 in Division One this season.
Having started their chase of 230 immediately after tea on day three, Lancashire had reached 66 for two before slipping to 95/7.
Coad claimed four for 14 from 10 overs, including his second, third and fourth scalps in an eight-ball spell.
That left Josh Bohannon and Keshav Maharaj with an unenviable task at the start of day four.
Maharaj crashed the first ball of the day from Coad for four through the covers, but he fell in the fourth over of the morning when bowled by Brooks for 18, leaving Lancashire at 122 for eight in the 42nd.
Brooks claimed his fourth wicket of the innings when he bowled Graham Onions at the end of the 48th over before Coad wrapped things up by getting Bohannon sharply caught at mid-wicket by Tim Bresnan at the second attempt at the start of the 49th - two wickets in two balls.
Speaking after the game, Lancashire Head Coach Glen Chapple, said: "Going into the last few games of season, we knew we had to win games. We've got ourselves into a position in the table that was precarious through losing close games.
"This one is disappointing because we had such a good first day and played so well. To not hammer that advantage home is frustrating. We didn't make enough runs and force Yorkshire into enough pressure.
"In the conditions they're used to here, they came back well and outplayed us for the last two days.
"If you take last season, whenever we lost early wickets, we had big partnerships to get us up to big scores. We haven't done that this year.
"Generally, as a batting unit, we haven't scored enough runs.
"The work ethic has been there, and we've got good players. But too many have had poor seasons."
