For the second time in a week, Adam Voges failed narrowly to complete a century as Nottinghamshire edged ahead at Old Trafford.
The 29-year-old, who withdrew from Australia's tour of South Africa to get married, was out on 95, having been dismissed on 99 against Worcestershire last week. Voges played well in tough conditions but was leg before wicket to Oliver Newby's late inswing. Kyle Hogg bowled well without success but Newby, with three wickets, was the pick of the Lancashire attack.
Out for 69 on Wednesday in reply to Durham's 543, Somerset were happy their follow-on was held up by rain at Taunton. They fought back in the afternoon, reaching 178-1, with former England opener Marcus Trescothick 10 runs short of a first hundred of the season and James Hildreth unbeaten on 52, when more bad weather ended play.
The Second Division promotion favourites Kent had to follow on against Essex at Chelmsford, despite the efforts of their South African all-rounder Wayne Parnell, who scored 69 with the bat yesterday. His runs took Kent to 205 all out but they still finished 15 short of avoiding the follow-on. They were 54-1 overnight.
Northamptonshire are facing defeat against Gloucestershire at Wantage Road. David Lucas claimed 4-39 as the visitors set the home side an unlikely 371 to win. They were five down for 177 at the close.
Boeta Dippenaar is on 85 as Leicestershire fight to save the game at Southgate, where Middlesex made them follow on 235 runs behind.
