There were wins on day four of the the latest round of Specsavers County Championship matches for Hampshire, Surrey, Essex, Glamorgan and Gloucestershire.
Elsewhere, Leicestershire are up to second in Division Two - behind Essex - despite drawing with Northamptonshire and Yorkshire were held to a draw in the Roses clash, making it a good set of results for Middlesex, who beat Durham yesterday.
Division One table
Beginning the day on 70 without loss, Lancashire declared on 232 for three once Haseeb Hameed had made his way to 100 in 124 balls. Tom Smith made 87 and Liam Livingstone 31 not out as they set Yorkshire a target of 367.
Yorkshire openers Adam Lyth (63 not out) and Adam Lyth (114 not out) then steered their side to 188 without loss at which points hands were shaken and the draw confirmed, with Lancashire taking 11 points from the match to Yorkshire's 11 - which now leaves them 26 behind them in second place.
Nottinghamshire resumed on 42 for two in their bid to bat through the day and stave off defeat to Hampshire but despite Steven Mullaney's excellent century, they fell well short, bowled out for 291 to go down to a heavy defeat.
Mullaney struck 137 in 227 balls while Brendan Taylor made 58 but Brad Wheal, making more of a name for himself as the season progresses, bowled Hampshire to victory with a haul of six for 51, supported by Mason Crane's three for 95.
This was just Hampshire's second win of the season but it was enough to move them off the foot of the table - Nottinghamshire replace them - and with four games to go they are 16 points behind Durham, who have a game in hand, and 17 behind Warwickshire, who have played the same number of matches.
Surrey leapt up to third by bowling Warwickshire out for 169 to complete a resounding 226-run win at Edgbaston.
Warwickshire began the day on two for one chasing an unlikely 396 to win and were quickly in trouble as they slipped to 52 for four and 77 for five, losing Jonathan Trott and Laurie Evans either side of the lunch break.
The wickets were shared among the Surrey bowlers, for whom Stuart Meaker, Mark Footitt and Gareth Batty took two apiece as they moved to within four points of Yorkshire in third place.
Division Two table
Essex duly completed an innings victory over Derbyshire to return to the summit of Division Two, and they now hold a very handy 23-point advantage over their nearest challengers Leicestershire.
Derbyshire offered little in the way of resistance on the final day and were bowled out for 303 as Graham Napier (4-50) passed 50 wickets for the season. Matthew Critchley made 43 for the hosts.
Leicestershire began the day on 49 without loss and ended it in second place in the table after claiming 11 points to Northamptonshire's 10 from this drawn match.
Paul Horton fell for 99 and Angus Robson 84 before Saif Zaib (5-148) took his maiden five-wicket haul and David Murphy - brought on to encourage Leicestershire to set a target - took his maiden wicket when Ned Eckersley was caught by Alex Wakely for one.
Leicestershire, in no mind to make things any more competitive than they had to, did eventually declare when they had reached 292 for six, setting Northamptonshire a target of 414 in 51 overs.
Wakely then hit an unbeaten 53 as Northamptonshire eased to 118 for one in 38 overs before the match was declared a draw.
Sussex wrapped up the first result of the day when they took the remaining one Gloucestershire wicket for just nine runs, which meant they weren't required to bat again.
Jack Taylor was bowled by Steve Magoffin for 56 and with Liam Norwell unable to bat, Sussex finished things off quickly to move to within four points of their opponents in the table.
Not many people would have picked Owen Morgan as the most likely of heroes with the bat for Glamorgan but he broke several records to lead his side to a five-wicket win over Worcestershire at New Road.
Sent in as nightwatchman last night, he progressed to his maiden half-century as Jacques Rudolph (26) and Will Bragg (46) fell at the other end, quickly followed by David Lloyd. At 150 for four, the match was in the balance, but Morgan was not to be denied.
Having broken the previous record for a score by a Glamorgan nightwatchman, he proceeded to hit a maiden century and the winning runs to guide his side to 278 for five and just their second victory of the season.
In all, he faced 103 in 242 balls and his partnership with Aneurin Donald (57), worth 99 for the fifth wicket, turned the game decisively in Glamorgan's favour.
