The visitors were bowled out for 161 in their second innings after Marcus Trescothick's third successive duck.

Vernon Philander was left unbeaten on 35, with Riki Wessels (30) the only other batsman to reach double figures,
|Evening things up|
|Somerset's victory brought them level with Notts on 31 wins each in Championship games between the two sides|
Having lost their first three matches of the season, the match appeared to run away from Somerset after they finished off the Notts first innings in the morning.
The home side were dismissed for 226, with Samit Patel the last to go for 56 as paceman Craig Overton claimed 4-40.
However, Trescothick's fifth-ball dismissal, bowled by Philander, sent Somerset's second innings into a downward spiral as they found themselves 59-6.
The lower order contributed useful runs to least give them something to defend and Notts, who have also yet to win this season, lost opener Steven Mullaney before a rain interruption.
When the players returned to the middle, the next seven Notts wickets went down in a clatter as they tottered to 82-8.
Somerset skipper Trescothick asked the umpires for an extra half hour and Groenewald wrapped things up by having Jake Ball caught at point and bowling last man Harry Gurney for nought.
Somerset skipper Marcus Trescothick:
"Getting 300 runs on the first day was crucial in the context of the match - 300 was far too many, after that the ball did plenty as the dents hardened up and made it tricky to bat on.
"We've worked on a few things over the last few weeks after a tricky start to the season, so we're constantly pushing in certain directions to get things right.
"In the New Zealand game last week we did some really good things with the ball and looked to carry that on and emulate it here.
(On his pair) "This is a tricky place to come, I think I've only ever won here twice in my career and I couldn't think of a worse place to come and face Vernon Philander, on that pitch.
"The ball he bowled me with in the first innings, if he bowled it 10 times I wouldn't have hit any of the 10."
