Rawnsley bowled Alex Loudon in his third over, but Michael Brown, an opener on the Middlesex staff, saw Durham through a tricky first session and then deep into the afternoon until a bat-pad catch ended a patient knock of 55.

Foster continued in his unflustered style in stands off 55 with Hugh Loudon and 44 with Tim Phillips, who were both lbw to Chris Liptrot to brighten a day of frustration for Worcestershire.
