Liam Trevaskis took three wickets in a brilliant last over as Durham snatched victory from the jaws of defeat against Lancashire at Emirates Old Trafford.

The part-time left-arm spinner from Carlisle, 19, defended just six off the last over and took his first wickets of the campaign as Lancashire chased a 155 target, slipping badly from a position of strength at halfway.

The Lightning needed 63 off the last 10 overs with six wickets left and finished on 150 for nine.

Trevaskis finished with four for 16 from his four overs in a four-run win which significantly strengthens their hopes of quarter-final qualification.

The second-placed Jets have moved to 14 points from 10 games, one behind leaders Worcestershire. Lancashire are fourth on eleven points from 10.

Earlier, Lancashire’s Afghanistan spinner Zahir Khan impressed with two for 19 on debut as their overseas player as Durham posted 154 for seven, a total which looked under par when Alex Davies flew out of the blocks in reply with 53 off 33 balls.

Khan, the 19-year-old bowling left-arm chinaman, has signed for the rest of the season on Jos Buttler’s recommendation having been squad mates at Rajasthan Royals in the IPL earlier this summer.

He finished with identical figures to fledgling seamer Danny Lamb, who was one of the three Lightning players to fall to Trevaskis in that dramatic conclusion.

Khan bowled flat and quick with variations aplenty, bowling Trevaskis around his legs as he tried to sweep and trapping Paul Collingwood lbw sweeping in an eye-catching four-over spell.

Durham started positively with the bat, reaching 56 for one in the seventh over.

But they stumbled through the middle in the face of Khan and Lamb, whose sister Emma also struck twice in a Kia Super League game earlier in the day.

In the end, the Jets did well to get up to 154 as veteran Will Smith hit three sixes in 37 not out. Their innings included nine sixes and only six fours.

Lamb had James Weighell caught at deep cover off a full toss and Stuart Poynter caught at mid-off in only his second Blast appearance of the summer and third in all.

Earlier, Jordan Clark caught younger brother Graham at long-on for 29 off leg-spinner Matthew Parkinson.

Chris Rushworth had Karl Brown caught at mid-on in the first over of the Lightning chase, but Davies quickly found his range on the way to a club record equalling fifth Blast fifty of the season.

Davies found useful support from pinch-hitter Arron Lilley (28). They shared 72 inside eight overs for the second wicket before Lilley was run out to leave the score at 78 for two in the eighth.

Davies reached his fifty off 32 balls in the 10th over, but he was caught behind off Ben Whitehead’s leg-spinners with his next ball - 88 for three.

Steven Croft miscued a return catch to Trevaskis (114 for four) as Lancashire’s target became 41 off the last six overs.

Whitehead (two for 23) struck again to remove Dane Vilas as the game tightened up significantly to 19 off two overs.

Jordan Clark fell to Nathan Rimmington in the penultimate before Trevaskis, who conceded only one in the last over, had James Faulkner caught at long-on, Lamb stumped and Matthew Parkinson caught at deep mid-wicket.

Lancashire face Yorkshire at Emerald Headingley on Thursday evening, while Durham host Leicestershire tomorrow.
