Worcestershire's openers gave them hope of avoiding a potentially catastrophic defeat at fellow LV= County Championship first division strugglers Durham.
Phil Hughes and Daryl Mitchell ensured there would be no repeat of the calamitous first-innings 126 as that batted through to lunch to be 64 without loss.
Australia opener Hughes led the counter-attack with an unbeaten 46, while the stoic Mitchell was on 16, as they reduced the first-innings deficit to 50 runs.
It was a position the Pears, bottom of the table, could only have hoped for when they were skittled on Tuesday but Gareth Andrew's five for 89 ensured Durham did not build a match-wining advantage.
Chris Russell claimed the final Durham wicket on Wednesday morning, to bowl the hosts out for 234, before Hughes and Mitchell negotiated the remaining 26 overs in the session.
Leaders Warwickshire were also able to sit back and watch their openers go to work as they reached 126 for none in reply to Middlesex's 287, with Ian Westwood (70) and Varun Chopra (42) adding 105 runs.
Marcus Trescothick scored his 50th first-class century but was one of five Somerset wickets to fall as Sussex spinner Monty Panesar reduced them to 247 for eight at Taunton.
Trescothick began the day 11 short of three figures and while he reached his milestone it was former England spinner Panesar who took charge.
Panesar removed Jos Buttler, Alex Barrow and Peter Trego to have figures of five for 60. Trescothick was caught behind of Chris Nash after striking 20 boundaries in his 123.
