Yorkshire were denied the chance to open up a 16-point lead at the top of the LV=County Championship table when Durham showed gritty determination in batting out the final day at Headingley.
The main consolation for Yorkshire was that the 13 points they gained from the draw placed them five points ahead of second-placed Nottinghamshire.
Although Yorkshire never gave up, Mark Stoneman (86), Michael Richardson (95) and Phil Mustard (57 not out) all made major contributions as Durham reached 323 for eight, giving them a lead of 128 with only 11 overs remaining.
However, Yorkshire’s frustration was tempered as talk of a thrilling finish between two other title chasers at Uxbridge came to nothing with Somerset comfortably hanging on for a draw against Middlesex.
Middlesex, almost certainly mindful of last month’s damaging loss to Nottinghamshire at Trent Bridge following a generous declaration, left it late before setting Somerset an improbable target of 390 for victory in two sessions and 20 minutes.
But with the pitch offering little, they never seriously threatened to take 10 wickets with Nick Compton adding an unbeaten 83 in Somerset’s 203 for four.
Both teams remain in LV= County Championship Division One title contention but may be left counting the cost of their failure to secure a win here.
In Division Two, promotion-chasing Hampshire avoided their first defeat of the season as Gloucestershire ran out of time at the Rose Bowl.
James Vince and Sean Ervine each made half-centuries as Hampshire survived a tense evening session before the captains shook hands on a draw with eight overs remaining.
By then, Hampshire were just six runs ahead with four second innings wickets remaining.
Two of those overs would have been lost in changing over the innings had Hampshire capitulated, so Gloucestershire were left to rue a bland, lifeless wicket and rain over the first two days which proved so costly in terms of vital time lost.
Sam Northeast hit his first century of the season as Kent cruised to a six-wicket win against Leicestershire at Grace Road.
With Northeast making an unbeaten 112 off 143 balls, Kent reached their victory target of 304 half-an-hour before tea on the final day.
Daniel Bell-Drummond and Brendan Nash also made half-centuries as Kent eased their way to 306 for four.
Nick Browne again halted Derbyshire’s advance as his second unbeaten century of the game combined with a hundred from Ryan ten Doeschate helped Essex to a draw at Chesterfield.
The 23-year-old Browne made 100 not out and shared a fifth wicket unbroken stand of 193 with Ten Doeschate (104no) who scored his first century in the Championship in nearly a year as Essex ended on 243 for four.
Derbyshire had set them 367 in 61 overs with Shivnarine Chanderpaul making 92 before the home side declared on 368 for eight.
