Yorkshire returned to the top of the LV= County Championship Division One table when they completed a comprehensive 220-run victory over Middlesex at Scarborough by bowling them out for 201.
The win put them five points ahead of second-placed Nottinghamshire and 16 points in front of Somerset, and each of the leading three sides have four matches still to play.
For a long while it looked as if Middlesex may well hold out but it was leg-spinner Adil Rashid who did much of the late damage with his season's best figures of four for 27.
Jonathan Trott held Warwickshire's top order together with an unbeaten 62 as his side reached 163 for three in response to Sussex's 413 on the second day at Horsham.
Trott has so far batted for just over three hours and despite one or two alarms looked in the mood to continue his outstanding record against Sussex. He has now scored a double hundred, four centuries and five fifties in 26 innings against them.
Trott and opener Varun Chopra led a steady response for Warwickshire with a third-wicket stand of 125 after they had lost Ian Westwood and William Porterfield by the 12th over.
In Division Two, Derbyshire celebrated back-to-back victories for the first time this season in the Championship as they beat Glamorgan by six wickets at Derby.
The home side needed only 70 minutes on the third day to reach their target of 73 and secure a 20-point haul although Glamorgan, who took only three points, made them work for their first home win in the Championship by taking three wickets.
Wayne Madsen, Ben Slater and Shivnarine Chanderpaul, who together with Mark Footitt was presented with a county cap after the match, were dismissed before Wes Durston completed Derbyshire's third victory over Glamorgan in two years.
Worcestershire's seamers strengthened the club's grip on the Division Two title by forcing Gloucestershire to follow-on at Cheltenham.
Having extended their first innings to 395 on the second day, with Daryl Mitchell finishing unbeaten on 167 and Craig Miles claiming five for 90, the visitors made short work of the home batting line up, claiming maximum bowling points for the 24th successive game.
At one stage Gloucestershire were 68 for eight before they were eventually bowled out for 156, with two wickets each for New Zealander Mitchell McClenaghan on his Championship debut, Charlie Morris, Jack Shantry and Joe Leach.
With five overs left in the day, the hosts reached 10 for one in their second innings, losing skipper Michael Klinger for five, and still trailed by 229.
Stuart Meaker shone with bat and ball on day three of Surrey's match against Kent at Guildford.
After scoring 53 from 73 balls as Surrey made 398 in their first innings, he then took four for 67 as Surrey reduced Kent to 229 for six at the close - only a moderate lead of 239 on a pitch that is still a good one for strokeplay.
