Twenty20 Cup, Derby: Derbyshire 157 all out (19.5 overs) beat Durham 151-5 (20 overs) by six runs
Neil Killeen's 4-32 and Gary Pratt's unbeaten 62 were not enough to stop Durham crashing out of the Twenty20 Cup with a six-run defeat to Derbyshire.
The Dynamos' hopes were high after they bowled their hosts out for 157.
But, on another low-scoring pitch at the Racecourse ground, the home bowlers were able to keep Durham under-wraps.
Medium-pacer Dominic Hewson again led the way with 2-20 off four overs.
The Scorpions face a crucial final match at Leicester on Tuesday, with the winner likely to top the North Division.
Killeen began the damage with the second ball of the innings, dismissing Dominic Cork, and finished it with the penultimate delivery, having Graeme Welch caught in the deep.
With 18-year-old pace man Liam Plunkett allowing as many runs from his four overs, and taking two wickets, the hosts appeared in trouble.
Michael di Venuto's 36 was matched by Hewson but neither man could find a willing ally as the Scorpions stumbled.
But the total proved enough despite Pratt's 62 from 44 balls.
