Lancashire wasted little time on day three in seeing off Hampshire, wrapping up a comprehensive 10-wicket win at the Rose Bowl before lunch.
Resuming on 163-5 in their second innings having been forced to follow on, the home county only managed to add a further 38 runs before they were all out for 201 during the morning session.
They had added only one to their overnight total when Kyle Hogg, Lancashire's hero with the ball on day two, dismissed Nic Pothas for a duck.
The same bowler also removed opener Benny Howell for 71 in his very next over and then had Dimitri Mascharenhas lbw for two to make it 188-8.
Dominic Cork at least ensured the visitors would have to bat again with a rapid 20 before he became Hogg's fourth victim of the innings, and 11th of the match, offering a catch to Gary Keedy.
Keedy himself then took the final wicket, bowling David Griffiths (two) to leave Lancashire needing just eight. They took just three balls to get them, Paul Horton clipping away two boundaries off Cork's bowling to seal the rout.
Lancashire have now won five of their first six matches in the LV County Championship and sit more than 20 points clear at the top of the Division One table.
Kyle Hogg's career-best figures of 7-28 allowed LV County Championship leaders Lancashire to make Hampshire follow on at the Rose Bowl.
Seam bowler Hogg took advantage of helpful conditions to run through the home side's line-up, including four caught behind dismissals.
The home side, replying to Lancashire's first-innings effort of 328 made on day one, were all out for 133 in just 41.4 overs despite having made a reasonable start during a second-wicket stand of 55 between Jimmy Adams (35) and Johann Myburgh (28).
But nobody else reached 20 as Hogg ran riot and Hampshire were then reduced to 163-4 in their second innings by stumps on day two.
Opener Benny Howell, making his first-class debut, stood firm with 68 not out and Hampshire will resume on the third morning needing another 32 to make Lancashire, who have started the season with four wins out of five, bat again.
Karl Brown missed out on a century after leading LV County Championship leaders Lancashire out of trouble on day one against Hampshire.
Having opted to bat first at the Rose Bowl, Lancashire were reduced to 65-3 with Hampshire seamer David Griffiths making two of the breakthroughs.
But Brown and Stephen Croft steadied the ship with a 100-run stand for the fourth wicket either side of lunch.
Both fell just before tea, Croft lbw to left-arm spinner Danny Briggs (1-25) for 37 and Brown caught behind for 96 off veteran seamer Dominic Cork.
Cork went on to finish with 4-78 as Lancashire were all out for 328 in the final over of the day.
