Another century from in-form captian Keaton Jennings saw his side beat Northants by 19 runs and move up to fourth in the Royal London One Day cup.

The opener has been in top form during the competition so far, averaging 80.60, and again provided the foundation for Durham to set a testing score of 291 in overcast conditions at Chester-le-Street.

The Steelbacks looked on course to chase down the total as Adam Rossington and Steven Crook put on 99 for the 6th wicket, but Paul Coughlin bowled Rossington for 69 to swing the match in Durham’s favour.

The win would have been more comfortable had Durham not been unusually ragged in the field.

But the victory means Durham look likely to qualify for the quarter-finals despite starting the competition with a two-point deduction.

After losing the toss, the North-East side were put in to bat in the gloom at the Riverside, and Jennings and Steven Cook were just finding their feet before the latter was trapped LBW by one that kept low from Ben Sanderson.

Jennings and Michael Richardson then put on a match-defining 158-run partnership for the second wicket. Richardson has also looked in form this year, and overcame a shaky start to hit two sixes in his 68.

However the star of the show was Jennings, who never looked in any trouble as he compiled his second century of the competition in typically composed fashion, ruthlessly punishing anything fractionally short.

Richardson was caught off the bowling of Richard Gleeson, and Jennings was dismissed soon after by Sanderson, which caused the innings to stutter.

A 50 partnership for the sixth wicket between Pauls Collingwood and Coughlin saw Durham post a decent target – Collingwood impressing with a fluent, unbeaten 53.

The visitors reply started poorly as they slumped to 57-3, with one wicket each for Chris Rushworth, James Weighell and Coughlin, the latter particularly impressing.

Richard Levi and skipper Alex Wakely led a recovery with a 55-run partnership but both went in quick succession as Collingwood first removed Wakely and then brilliantly ran out Levi, who looked in good touch for his 66.

At this point the game looked Durham’s to lose but a 99-run stand between Rossington and Crook looked to be wrestling back control for Northants, who needed 69 to win off 51 balls.

However, Rossington attempted a ramp shot off Coughlin – a very poor shot selection given that he was easily maintaining the run rate with orthodox shots – and was bowled.

The game then petered out, as the Steelbacks’ tail was unable to deal with Durham’s accurate death bowling. Weighell removed Crook to kill off Northants, who never looked like reaching the target after the loss of Rossington.
