KEATON Jennings becoming the first batsman in the country to 1,000 championship runs provided the only relief from Durham's slide to a heavy defeat at Lord's yesterday.

They were all out for 252 to lose by an innings and 80 runs with a day to spare.

Middlesex made hay in the glorious sunshine before declaring 332 ahead on 536 for nine, then quickly handed off-spinner Ollie Rayner the task of dismantling Durham.

Batting looked reasonably straightforward until he come on at 49 without loss after 13 overs, Jennings passing his milestone when he drove two fours through the covers off Toby Roland-Jones in the fourth over.

Middlesex's Nick Gubbins was on 999 when he was out for 145 the previous day, while Kent's Sam Northeast is on 995.

As in Durham's defeat at Taunton this pitch started dry and took spin on day one, when Rayner had four for 17.

He followed up with five for 85, striking in his third over when he dived to his left to hold a return catch from a Mark Stoneman drive, ending Durham's second half-century opening stand of the match and ninth of the season in the championship.

It signalled a decline from 55 without loss to 115 for four at tea, with the other three victims all falling lbw – a decision Durham had failed to extract from the umpires in the Middlesex innings.

Rayner was awarded two of them, straightening one to defeat Jennings on 45 before Scott Borthwick was also pinned in front by a shooter from James Franklin in the next over.

That was an indication of the increasingly uneven bounce as the pitch baked under the hot sun and Adam Hickey was out of luck for the second time in the match when a sharp lifter from Harry Podmore had him caught behind.

Podmore also nipped one back to bowl Paul Collingwood off his pads as Middlesex reverted to seam after Jack Burnham had taken on Rayner.

After spoiling his first appearance at Lord's by getting himself run out for nought in the first innings, the youngster refused to let Rayner tie him down.

He swept him for four to get off the mark, then pulled another boundary and added four more his way to 30.

But when he shaped to off drive Tim Murtagh the ball nipped through the gate to bowl him.

As in the first innings there was good resistance from Paul Coughlin and Mark Wood until Rayner returned and had Coughlin caught off bat and pad for 39.

In the morning Wood bowled Rayner in the third over, only for the previous day's misfortunes to return as Franklin skied a pull off Wood into leg-side space before surviving yet another confident lbw appeal from Graham Onions.

Once Wood rested, looking rather disconsolate, Roland-Jones opened his shoulders to smash four sixes in hitting 66 off 47 balls.

Once he had been caught on the long boundary at mid-wicket by Burnham off Hickey, Tim Murtagh also came out swinging and was dropped at long-off by Chris Rushworth, who had to leave the field because of a dislocated finger.

The bowler, Borthwick, had none for 132 at the time but finally claimed a wicket when Murtagh drove to the same position and substitute Ryan Pringle held the catch. Franklin promptly declared, unbeaten on 56.

While he continues to contemplate his future, this has been another poor match for Borthwick with 12 runs to follow 25 at Taunton.

Despite his Man of the Match performance in Wednesday's T20 quarter-final, Michael Richardson also continues to struggle in the championship, falling lbw on the back foot to Rayner for two.

As they look to the future, Durham will have to consider more opportunities for Stuart Poynter. But after taking a total of five points from their last two games, the priority will be to win one of the next two, at home to Warwickshire and Nottinghamshire, to stay out of trouble.
