Somerset closed out a dominant 10-wicket win over Essex at Chelmsford for a first Rothesay County Championship victory of the new campaign.
After Craig Overton's career-best 141 had helped put the visitors in a strong position at Chelmsford, Essex had resumed at 131 for three.
However, once overnight batters Matt Critchley (59) and Paul Walter, who was caught and bowled by stand-in skipper Overton, went in quick succession, Essex were then dismissed for 245.
Somerset needed only 47 for victory, which injury substitute Archie Vaughan - son of former England captain Michael - soon helped rattle off, making a swift 41, hitting two sixes.
Durham beat Gloucestershire by an innings and 225 runs in their Division Two match in Bristol, with Callum Parkinson taking three wickets.

Matthew Potts also claimed three for 49 as Gloucestershire were all out for 205.
Worcestershire beat Middlesex at Lord's by 57 runs. Middlesex had given themselves hope after dismissing Worcestershire for 253, with Matthew Waite contributing what proved to be 34 vital runs. Ryan Higgins finished with four for 68.
Worcestershire, though, fought back with the ball. Tom Taylor claimed three wickets as Middlesex were all out for 204, all-rounder Waite having taken two for 29. Joe Cracknell was unbeaten on 43.

England hopeful Asa Tribe had made an unbeaten 59 by lunch, but no play was possible before tea as the rain set in.

Sussex need 94 runs to beat Warwickshire, with five wickets remaining at Hove.

Resuming at 350 for three, Rishi Patel, 133 overnight, was out for 164, but further determined centuries from Stephen Eskinazi (100) and Cox helped push the visitors on.
Hampshire are closing in on victory over Yorkshire at Headingley.
An unbeaten 103 from captain Ben Brown and Jake Lehmann's 92 helped Hampshire reach 351 for five declared, setting a target of 426.
