Edgbaston (fourth day of four): Warwickshire 341 & 264, Nottinghamshire 297 & 138 - Warwickshire win by 170 runs
Warwickshire blew the LV=Insurance County Championship Group One wide open after beating Nottinghamshire by 170 runs in a pulsating contest at Edgbaston.
Set a victory target of 309 in 74 overs, the visitors were bowled out for 138 with eight overs to spare as spinner Danny Briggs followed up his important runs in the match with a decisive spell of 4 for 36.
After the Bears took their overnight 201 for 6 to 264 all out, they bowled with collective skill to close out a thrilling victory.
At 89 for 5, Nottinghamshire had no choice but to abandon their quest for a fourth successive victory and their hopes of defending out for a draw were scuppered as the Bears maintained the pressure with disciplined bowling supported by excellent fielding.
In the morning, Burgess and Briggs took their partnership to 103 in 33 overs before the former top-edged a sweep at Liam Patterson-White to slip. Craig Miles was soon run out by Ben Slater's direct hit, before Fletcher rattled the stumps of Briggs and Liam Norwell.
Norwell then soon struck with the ball as Haseeb Hameed edged to wicketkeeper Burgess and two big wickets fell in successive overs when Ben Duckett swept Danny Briggs to Rob Yates at deep square and Ben Slater nicked Tim Bresnan behind.
A brilliant legside stumping by Burgess off seamer Olly Hannon-Dalby dismissed the dangerous Joe Clarke and when Steven Mullaney pulled Hannon-Dalby to deep square, it was 89 for 5.
Lyndon James and Tom Moores ate up valuable time in a stand of 16 overs, but when both fell in quick succession, Moores leaving a straight one from Will Rhodes and James edging Briggs begin the visitors were vulnerable again.
When Briggs winkled out Chappell, caught at silly point, he had post-tea figures of 2 for 0 from 10 overs. Patterson-White's 72 minutes of defiance ended rather unluckily when a defensive shot off Miles dropped the ball back on to the stumps.
That left numbers 10 and 11 with 11 overs to survive - and they managed just three before Fletcher was bowled an absolute pearler from Biggs to the delight of a boisterous crowd in the Birmingham sunshine.
