COUNTY CHAMPIONSHIP DIVISION ONE, Liverpool:
Lancashire 398 & 171-7 beat Hampshire 160 & 405 by three wickets
(Lancs 22pts, Hants 3pts)
Adams also reached three figures against Lancashire in the FP t20 in June
Lancashire kept their slim County Championship title hopes alive with a tense win over Hampshire at Aigburth.
Jimmy Adams looked like he might save Hampshire from defeat as he went on to make a defiant 194 from a marathon 508 balls out of the visitors' 405 all out.
But he was last out on the stroke of tea, leaving Lancashire needing a brisk 168 to win from the final session.
And, after Shivnarine Chanderpaul went for 51, Kyle Hogg and Mark Chilton won it with just a ball to spare on 171-7.
The victory lifts Lancashire to within seven points of third-placed Yorkshire, narrowing the gap on leaders Nottinghamshire to an admittedly chasm-like 31 points with two games left.
But, although it is a very tall order, Lancashire's last two games are against the top two - against Somerset at Taunton next week (7-10 September), followed by a home date with Notts at Old Trafford (13-16 September).
Adams, who hit his first ton in Twenty20 cricket also against Lancashire in June, this time showed his versatility as a batsman.
After coming to the crease late on Wednesday afternoon, he had batted throughout the whole of the third day to reach the close on 109. And, in the end, the 29-year-old left hander's crease occupation lasted for 10 hours and 35 minutes, as he recorded the longest innings of the summer.
Victory had looked a near certainty for Lancashire at the start of the final day when Hampshire resumed on 275-5, only 37 ahead. But the hosts were made to sweat even more when Adams shared a last-wicket partnership of 88 in 43 overs with Danny Briggs (15 not out off 97 balls).
That left the hosts with just 33 overs to make that 168 to win at five and a half an over - and left-arm swing bowler James Tomlinson then made life even more uncomfortable when he took three quick wickets to reduce Lancashire to 17-3.
But the reliable Chanderpaul helped to steady the ship, with the support of some measures hitting, first from Gareth Cross, then Saj Mahmood.
And, although Chanderpaul went with 28 still required, Chilton hit the satisfaction of striking the winning runs off Lancashire old boy Dominic Cork with one ball and three wickets to spare.
Earlier, Lancashire all-rounder Tom Smith recorded figures of 6-94 from 41 overs to clinch career-best match figures of 9-134.
