Division One leaders Warwickshire were on the victory hunt at Taunton this morning - despite a second-innings collapse.
The Bears were skittled for 124 by Somerset but, defending a lead of 270, had reduced their hosts to 15 for two by lunch.
Both of Somerset's openers - Alex Burrow and Arul Suppiah - were sent back to the pavilion, leaving Nick Compton and James Hildreth to survive until the break.
Earlier, Gemaal Hussain's five for 48 had seen off Warwickshire, although they remain in control thanks to their first-innings 400.
Durham were also smelling a victory, but with a much smaller total to look after against Sussex.
Paul Collingwood's men were all out for 93 this morning - Steve Magoffin taking six for 22 off 12.4 overs - but had Sussex on the ropes at 41 for five in their pursuit of 94.
Chris Rushworth and Callum Thorp took two wickets apiece, with Sussex resting a lot of their hopes on obdurate veteran Murray Goodwin (13 not out).
There was little doing at Trent Bridge, though, as Nottinghamshire's rain-affected clash with Surrey meandered along, with the home side 307 for seven at lunch, with Chris Read dismissed for 98.
