Lancashire 139 for 4 (Salt 74*) beat Northamptonshire 138 for 7 (Lynn 35, Wood 3-17) by six wickets

Lancashire made it through to the Vitality Blast quarter-finals with a comfortable six-wicket victory that also ended Northants Steelbacks' qualification hopes.

Phil Salt smashed a 51-ball 74 as Lancashire chased down the Steelbacks 138 for seven with twenty balls to spare. The result means the Lightning will return to Emirates Old Trafford next Friday, where they are now unbeaten in 21 home games, to host their quarter-final tie against Surrey.

Northants struck two early blows as the hosts set off in pursuit of their target, Jos Buttler cracking a short ball from David Willey to Saif Zaib on the cover boundary for 11, immediately after he had hit the bowler for six and four from consecutive deliveries. Steven Croft swiftly followed after top edging Tom Taylor to AJ Tye for 5.

That left the Lightning ending the powerplay on 43 for 2 but Salt picked up the scoring with a six off Freddie Heidreich during a 35-run partnership in five overs with Liam Livingstone.

Livingstone, the stand-in Lightning skipper, went for 11 slicing Taylor to Ricardo Vasconcelos at gully as Lancashire reached halfway on 74 for 3 but Daryl Mitchell was quickly into his stride driving Taylor for six into the pavilion seats.

Salt continued to score freely as the hosts reduced their target to a-run-a-ball 44 before a mix-up saw Mitchell run out for 17. Undeterred, Salt reached a 40-ball half century by smashing Tye for six over long-on, and then took four, six, four off Justin Broad in the fifteenth over as the Lightning raced towards their target.

The opening bat ended the contest in style with six off Taylor in the seventeenth over to finish unbeaten on a Lancashire-best 74 alongside Dane Vilas.

A fine opening spell of 2 for 14 from three overs by Wood, after Livingstone had put the visitors in to bat, had Northants quickly on the back foot at the start of their innings. Vasconcelos was brilliantly caught for 12 by wicketkeeper Buttler diving to his left, followed by Emilio Gay who chipped the left arm quick to Luke Wells at mid-on two balls later.

Northants then suffered a big blow when Willey departed for 10 attempting to hit Livingstone over midwicket to leave the Steelbacks struggling on 47 for 3, midway through the seventh over.

Chris Lynn led an initial fightback launching Livingstone for consecutive sixes in the ninth over but he was then bowled for 35 aiming a big heave at Wells with the visitors on 74 for 4, one ball into the 11th over.

Zaib pulled Mitchell to Wells at fine leg for 12 and the Steelbacks only managed to get any impetus into their innings during a 40-run partnership for the sixth wicket between McManus and Broad. McManus hoisted a slower ball from Tom Bailey into the hands of Wood at long-on having made 22 while Broad smashed a six over midwicket in his unbeaten 34 off 26 balls.

Wood returned to bowl Tye for 1 as Northants closed on 138 for 7.
