Nottinghamshire fell to a 399-run defeat at Taunton after a challenging third day at Taunton in the LV= Insurance County Championship.
James Rew notched a century as his side ran up 514 for eight declared in their second innings to set their opponents a victory target of 492.
George Bartlett, unbeaten on 109 overnight, fell for 134, just three short of his career-best score, while Kasey Aldridge weighed in with 50. Lyndon James had the best bowling figures for Notts with two for 64 from 18 overs.
The visitors then slumped to 92 all out in their second innings, taking three points from the game, keeping their place in the middle of the Division One table.
Somerset began the day on 268 for four, knowing that the second new ball was just an over away. Any hopes Notts had using it to re-establish their first day advantage soon disappeared.
Bartlett and Rew, who set out on 17, batted confidently through the opening hour, taking few risks and eliminating the errors that had cost Somerset dear in their first innings.
They had taken their fifth-wicket stand to 89 and the total to 320 when Bartlett, who had begun his innings with his team 43 for two, was bowled by Dane Paterson, having faced 265 balls.
The young left-hander Rew reached a typically unflurried fifty off 105 deliveries and played through the morning session without alarm.
By lunch, he had moved to 60 and the lead was 342. Aldridge was on 17 and the afternoon session saw the pair build another substantial stand.
Aldridge took the lead past 400 with a cover driven boundary off Brett Hutton before Rew brought up the fifth first class hundred of his short career off 172 balls.
Aldridge was then bowled by James, having hit 5 fours. By then Somerset had posted 447 for six and their lead had grown to 424.
By the time he Abell opted to declare, Craig Overton and Matt Henry had warmed up for their bowling duties with some lusty blows.
Notts reply began in trying fashion when Haseeb Hammed was run out without scoring, sent back attempting a single to backward point and undone by Bartlett’s direct hit.
It was two for two when Henry, bowling around the wicket, jagged one into left-hander Ben Slater’s pads to pin him lbw and 10 for three when Matthew Montgomery edged a defensive shot off Overton to Aldridge at second slip.
Notts captain Steven Mullaney found himself walking to the crease at 14 for four after Joe Clarke had been snapped up at second slip by Overton to give Henry his eighth wicket of the match.
Soon Notts were 62/6 with the skipper and James departing.
Hutton sportingly walked when inside-edging Davey to wicketkeeper Rew, who claimed another victim when Tom Moores, who top scored on 24, nicked a ball from Aldridge.
Davey then cleaned up Jake Ball and Paterson to spark joyous celebrations among home supporters.
