Lancashire batted through the final day at the Ageas Bowl to earn a draw against Hampshire in their LV= County Championship Division Two clash.
Middle-order batsmen Gareth Cross and Steven Croft benefited from captain Glen Chapple's decision to each score rare centuries.
The visitors began the last day 63 for three in their second innings, a lead of 100.
But skipper Chapple was mindful of Hampshire opener Michael Carberry's destructive spell against his side a few days previously in the Yorkshire Bank 40 fixture, so he was happy to settle for bonus points.
Although they eventually declared 410 runs ahead, there was no time for a Hampshire response and the match ended in a draw after 88 overs were lost to rain over the first two days.
Cross' century was his third in first-class matches and Croft's was his sixth as the match meandered towards its inevitable conclusion once Chapple had decided against offering Hampshire a target and only three wickets fell all day.
First innings century-maker Andrea Agathangelou went at 126, Karl Brown departed at 137 and Cross was removed at 298 soon after completing his ton.
Chapple waited until Croft had reached three figures before putting the small crowd out of their misery.
Hampshire captain Jimmy Adams used nine bowlers including himself in a bid to undermine the Lancashire batting, but for Cross and Croft in particular it was all too comfortable.
