LV County Championship - Division Two
Taunton - day three
Nottinghamshire 158 (C M Willoughby 4-39) & 190 (B M Shafayat 57, M K Munday 8-55) v Somerset 469 (I D Blackwell 141, P D Trego 113 no, M E Trescothick 112)
Somerset (22pts) beat Nottinghamshire (3pts) by an innings and 121 runs
Division Two champions Somerset needed just half-an-hour on day three to complete their 10th win of the season by a margin of an innings and 121 runs against Nottinghamshire.
Nottinghamshire - who had already also gained promotion back to the top-flight - resumed at 147-7 in their second innings, requiring another 164 to make Somerset bat again at Taunton.
But the visitors subsided to 190 all out in quick time as Somerset leg-spinner Michael Munday completed career-best figures of 8-55.
Munday's 2-10 in the first innings meant he also finished with a maiden 10-wicket match haul.
The 22 points earned by Somerset for the win allowed them to finish the season with a record 266 points, beating Surrey's haul of 262 achieved last season.
There was also an ovation for umpire Roy Palmer, a former Somerset player, who had been standing in his final first-class match.
Somerset should close out victory in less than three days against Nottinghamshire after piling on the runs and then reducing the home side to 147-7 in their second innings.
Marcus Trescothick was one of three players to make centuries for Somerset, along with Ian Blackwell and Peter Trego, as they put on 469 for a lead of 311.
Resuming on 194-4, Trescothick and Blackwell took their partnership for the fifth wicket to 204 before Blackwell was out for 141, which came from just 121 balls and included 18 fours and three sixes.
Trescothick fell shortly after for a more circumspect 112, before Trego took on the Nottinghamshire attack and lashed an unbeaten 113 from 120 balls, smashing 16 fours and two sixes.
Nottingham-born leg-spinner Michael Munday then took five wickets before the close to leave his home county on the brink of defeat.
Openers Bilal Shafayat (57) and Will Jefferson (44) put on 98 for the first wicket before Notts collapsed, losing seven wickets for 45 runs.
Nottinghamshire were bowled out cheaply by Somerset at Taunton, but duly picked up the bonus point they needed to make absolutely certain of promotion to Division One.
Charl Willoughby picked up four wickets for 39 as Somerset bowled out their visitors for 158, Mark Wagh top-scoring with 41 from 34 balls for Notts.
Marcus Trescothick then continued his fine form with the bat, hitting an unbeaten 76 as the home side responded by reaching 194-4 and a lead of 36.
Ian Blackwell also showed up well, making an unbeaten 70 as the pair put on an unbroken stand of 96 to rescue Somerset from 98-4.
Blackwell cracked 10 fours and a six to reach 70 from just 57 balls.
