Lancashire 273 (Jones 68, Edwards 4-78) and 113 for 2 (Livingstone 48*, Jennings 40*) beat Hampshire 187 and 198 (McManus 44*, Gleeson 4-43) by eight wickets
Lancashire's comfortable eight-wicket victory over Hampshire could hardly have been more bittersweet. Not only had their relegation to Division Two been confirmed on the second day, the impending defeat of Nottinghamshire on the third was expected to confirm that if Lancashire had reached a third batting point on the second day - they fell 27 runs short - they would have stayed up.
Keaton Jennings, who is about to face an England tour in Sri Lanka that could decide his Test future, supervised Lancashire's chase for 113. They got home in 13 overs by eight wickets, losing two wickets in two balls during their chase of 113, as Hampshire's veteran quick Fidel Edwards took his season's tally to 54 wickets.
Edwards found the outside of Alex Davies' bat to bring a diving catch for Sam Northeast at third slip before producing a bullet delivery to dislodge debutant Brooke Guest's off-stump.
Jennings, though, carried Lancashire over the line in attacking style, carting Kyle Abbott for four boundaries in his first over.
Liam Livingstone, 48 not out, added the remaining 73 with Jennings in aggressive style with the captain completing the eight-wicket victory by smashing Ian Holland over the top of the leg side in successive balls.
Lewis McManus had started the day alongside Abbott with a lead of 92, but only four runs were added before the first of the two remaining wickets fell. Abbott, who ended the season with a creditable batting average of almost 26 from No. 10, was bowled by a big inswinger from Tom Bailey for 21
McManus, now with Fidel Edwards, eked Hampshire's lead over 100 before the West Indian was bowled, again by Bailey - who claimed eight wickets in the match.
The scalp meant Bailey completed the campaign as the highest wicket-taker in Division One, with 64 wickets - seven more than teammate Graham Onions and Essex's Jamie Porter, who had the chance to add more in an unfinished match at Kia Oval.
It also meant McManus was left stranded on 44 on his first Championship appearance since June, having lost the wicketkeeping gloves to Tom Alsop.
The defeat means Hampshire will have to wait until after Yorkshire's match with Worcestershire is concluded to discover whether they finish fourth, for the first time in the club's history, or fifth.
