Somerset maintained their title charge with a crushing nine-wicket win inside three days against Sussex at Taunton.
After skittling Sussex for just 134 in their second innings, Marcus Trescothick steered his side past the meagre 94 target with an unbeaten half-century.
Seamer Alfonso Thomas (4-28) and spinner Murali Kartik (4-46) did the damage with the ball, ultimately ensuring that Somerset sped to their third successive win with over a day to spare.
Somerset took 21 points to the four earned by Sussex and are generating real momentum in their bid for a first-ever title success, having been pipped by Nottinghamshire on the final day last season.
Play was delayed until 1.40pm by morning rain but Somerset wasted little time thereafter as Sussex lost their remaining six wickets for just 40 runs.
Michael Yardy and nightwatchman Joe Anyon played out four maidens before Thomas struck a double blow from the Old Pavilion End. In the space of three balls he had Yardy caught at third slip by Kartik for two and pinned Ben Brown leg-before to make it 94-6.
Charl Willoughby replaced Thomas and he needed only two deliveries to dispose of Ollie Rayner, caught behind for eight, and Anyon (11) and Monty Panesar (2) swifly departed lbw to Kartik.
Wayne Parnell was caught in the slips by Trescothick at the second attempt for 13 to give Thomas only his second 10-wicket match and the South African was given a generous ovation as he led the team off.
Trescothick had no intention of hanging around chasing such a small target and finished unbeaten on 54 from just 47 balls with Arul Suppiah - expertly caught and bowled by Rayner - the only wicket to fall.
Jos Buttler hit a superb 109-ball century on Wednesday to rescue Somerset on the second day of their LV=County Championship match against Sussex at Taunton.
The 20-year-old smashed four sixes and 11 fours to transform the match after title-chasing Somerset had slumped from 36-1 to 93-7 in reply to Sussex's 245, with Monty Panesar claiming five wickets in the morning session.
Somerset added 15 runs before Panesar claimed night-watchman Steve Kirby, Chris Jones and James Hildreth (both for ducks), with Wayne Parnell dismissing Arul Suppiah (14) inbetween times.
Buttler began his innings alongside Nick Compton (16) before Panesar claimed him too, with the spinner then taking the scalp of Peter Trego first ball on his way to figures of 5- 26 from 11 overs.
Somerset were 124-7 by lunch. However, Buttler, who made exactly 100, then shared an eighth-wicket stand of 142 with Alfonso Thomas, who battled away for nearly three hours to make 42. Murali Kartik also added 34 at number 10 before Somerset were bowled out for 286 to earn a first innings advantage of 41.
By the close Sussex had made 94-4 in their second innings to lead by just 53, losing the cream of their batting in Chris Nash (eight), Luke Wells (18), Ed Joyce (34) and Murray Goodwin (six).
Alfonso Thomas claimed his best figures in in English first-class cricket as Somerset bowled out Sussex for 245 on the first day of their clash at Taunton.
The 34-year-old claimed 6-60 as he caused havoc during 22.1 overs from the River End with his pace and skill, beating the bat on numerous occasions.
Ed Joyce (59) and Murray Goodwin (55) bolstered the visitors' total but it was Somerset who edged the day's play thanks to an impressive display of bowling.
Michael Yardy also contributed 31 runs but Sussex were not able to string together any meaningful partnerships as wickets fell at regular intervals.
Thomas had four of his victims caught behind by Jos Buttler, while he also trapped Joyce and Monty Panesar (one) lbw, with his final wicket coming when Wayne Parnell (19) drove a catch to mid-off.
Somerset lost the LV= County Championship's leading run-maker Marcus Trescothick (14) before the close and will resume the second day on 36-1.
