Captain Alviro Petersen smashed 144 from 89 balls as Glamorgan beat Lancashire by 69 runs in the Clydesdale Bank 40 at Colwyn Bay.
Gareth Rees shared in a first-wicket stand of 199, while late blows from Graham Wagg and Stewart Walters saw Glamorgan post 328 for 4 from 33 overs.
Lancashire lost Tom Smith early in their reply in the rain-affected match.
Steven Croft hit 85 from 54 but fell to Dean Cosker, who took 4 for 43 as Lancashire were all out for 259.
BBC Wales cricket correspondent Edward Bevan:
"Alviro Petersen played one of the great one-day innings for Glamorgan as the home side gained a crushing victory over Lancashire.
"As Glamorgan scored their highest ever total in Colwyn Bay, a mammoth 328 for 4, Petersen struck 144 from 89 balls which included 10 sixes.
"He shared an opening partnership of 199 with Gareth Rees, who scored 76, and then Graham Wagg and Stewart Walters shared 75 from only 25 balls.
"In reply, Lancashire made a brave effort to score at 10 runs an over but no one could master the guile of Dean Cosker who ended with 4 for 43 from his seven overs."
Lancashire all-rounder Steven Croft:
"I think until six over left we were plus what they were despite the wickets.
"We thought it would be a hard ground to shut people down on and in the end we were probably chasing a bit too many than we'd like really.
"We couldn't really shut him down (Alviro) Peterson when he was batting and he was clearing the ropes by a long way - we tried most things, but he put us under a lot of pressure."
