Maia Bouchier and Grace Potts star, Warwickshire beaten

WOMEN'S T20 BLAST ROUNDUP: There were comfortable wins for Somerset and Hampshire, while The Blaze secured a tight victory over Lancashire

Trent Bridge: The Blaze 135-9, Lancashire Thunder 120 - The Blaze won by 15 runs

Lancashire's Grace Potts took a career-best 5 for 20 only for Australian allrounder Charli Knott to deliver the match-winning performance as The Blaze moved to the top of the Vitality Blast Women's points table with a 15-run victory as Thunder were dismissed for 120 at Trent Bridge.

Potts bowled superbly as The Blaze were restricted to 135 for 9 despite Tammy Beaumont making 59 from 40 deliveries with eight fours.

But Knott's 4 for 17 – also a career-best – trumped the Thunder seamer as the visitors were dismissed for 120 in 19.1 overs, the off-spinner inflicting the biggest damage with a triple-wicket maiden in the seventh over of their innings. Skipper Ellie Threlkeld's 49 from 36 balls proved in vain.

Georgia Elwiss took three for 12 and two key catches as The Blaze made their experience count after Beaumont, her 34-year-old teammate, was dismissed by Thunder's 16-year-old leg-spinner Venus Weerappuli, who was born on the day The Blaze opener was making her England debut in 2009.

Taunton: Warwickshire Bears 123-8, Somerset 126-5 - Somerset won by five wickets

Niamh Holland top-scored to guide Vitality Blast frontrunners Somerset to a five-wicket triumph over winless Warwickshire Bears at the Cooper Associates Ground, Taunton.

The in-form allrounder posted 42 from 31 balls, struck five boundaries and dominated a third wicket stand of 54 with Anika Learoyd as the home side chased down a victory target of 124 with 3.4 overs to spare.

Somerset's fourth win in five games was underpinned by a solid performance in the field, spinners Liv Barnes and Chloe Skelton claiming 2 for 20 and 2 for 21 respectively as Warwickshire were restricted to 123 for 8. Meg Austin and Mary Taylor top-scored with 31 apiece for the visitors, who lost wickets at regular intervals and struggled to build partnerships.

Chelmsford: Hampshire Hawks 155-4, Essex 100-9 - Hampshire won by 55 runs

Maia Bouchier blazed 87 from 55 balls, the highest score of this year's Vitality Blast, before Amanda-Jade Wellington claimed a hat-trick to maintain Hampshire Hawks' rise up the table with a resounding win over Essex.

Opener Bouchier – who featured in England's recent T20I series against New Zealand but was left out of their World Cup squad – hit two sixes and eight fours as she batted almost right through the visitors' total of 155 for 4 at Chelmsford.

Hampshire's spinners then got to work, with skipper Georgia Adams' four overs bringing her 3 for 18 before Wellington dismissed Jodi Grewcock, Flo Miller and Sophia Smale in consecutive deliveries to effectively end the contest. The Australian leg-spinner finished with 5 for 18, her best haul of the tournament so far, as Essex stumbled to 100 for 9.
