Middlesex were bowled out for 245 as Somerset won by 87 runs.

Elsewhere in the South Conference, current Australia pace bowler Clark took four for 25 for Hampshire as Glamorgan were bowled out for 146 at Swansea. Hampshire, having scored 283 for six, won by 137 runs.

South Africa all-rounder Andrew Hall starred with bat and ball as Kent thrashed Sussex by 112 runs at Hove.

Hall's 123 took Kent to 264 for nine and he then dismissed both Sussex openers as the hosts were bowled out for 152.

England opening batsman Alastair Cook warmed up for Thursday's third Test against the West Indies with 125 as Essex beat Surrey by eight runs at Whitgift School.

Cook struck 12 fours before being run out as Essex made 248, with Pakistan's Azhar Mahmood taking four for 29.

Surrey were looking good while ex-England batsmen Mark Rampra-kash (77) and Mark Butcher (53) were at the crease but Danish Kaneria took four wickets as the hosts were beaten in the competition for the first time this season to open up the semifinal race.

New Zealand captain Stephen Fleming made 107 as Nottinghamshire beat Midlands rivals Leicestershire by 24 runs.

Sri Lanka wicketkeeper Kumar Sangakkara scored 115 and Darren Maddy 106 for Warwickshire against neighbours Worcestershire at New Road.

Graham Wagg took four for 36 as Derbyshire bowled out hosts Scotland for 102. Derbyshire lost four wickets on the way to their modest victory target but still won with plenty in hand.
