Strauss continues to struggle
Andrew Strauss' struggles continued for Middlesex on Saturday, while Lancashire endured a nightmare day against Warwickshire.
After a modest winter with England Strauss was sent back to Lord's to get some runs under his belt but fell to Graham Onions for a duck on day two.
Onions proved his undoing once again as he clean bowled his international skipper for six.
Middlesex resume on 21 for one, 29 behind after bowling out Durham for 238 inside 59 overs.
Ben Stokes top-scored in that innings with 45, with England's Steven Finn taking three wickets.
Lancashirem meanwhile, are staring at the prospect of a second defeat in as many games as they endured a nightmare day against Warwickshire at Aigburth.
Things had started well for the Red Rose, with two early wickets from Simon Kerrigan reducing the Bears to 81 for seven in reply to 250.
Then a stunning partnership of 214 between Darren Maddy (112) and Rikki Clarke, whose 140 contained 13 fours and three sixes, carried the visitors to 329 all out.
The Lancashire's top three were blown away by Keith Barker as they slumped to 44 for four at stumps, 35 behind.
Somerset's Nick Compton continued his prolific start to the campaign as he hit his second first-class double century of the season against Nottinghamshire at Trent Bridge.
He hit 204 not out in a 217-run third-wicket stand with James Hildreth, who made 102no.
That meant three of the visitors' top four reached three figures, with Arul Suppiah earlier reaching 102.
That powered Somerset to 445 for two declared, with the home side managing 47 without loss at stumps, still 236 adrift.
