The Blaze 197 (S Bryce 34, K Bryce 31, Morris 6-35) beat Thunder 173 (Norris 53, Ballinger 4-23) by 24 runs

In a low-scoring contest, The Blaze - having started well - were pegged back to 197 all out at the hands of Morris once the spinner was introduced into the Thunder attack in the 30th over.

The Blaze made a good start after being put in to bat with Sarah Bryce and Michaela Kirk laying a good foundation of 66 runs off 87 balls. But both openers fell in quick succession. Sarah Bryce was caught at mid-off for 34 trying to hit Darcey Carter, making her Thunder debut, over the top with Kirk bowled for 29 by Hannah Jones' second delivery.

And The Blaze were pegged back further when Marie Kelly edged behind for 7 off the first ball of Phoebe Graham's second spell to leave the visitors 101 for 3 in the 24th over.

Kathryn Bryce and Ireland all-rounder Orla Prendergast rallied with a 34-run alliance off 45 balls before the introduction of Morris transformed the innings as wickets tumbled.

The Thunder off-spinner struck with a 17-ball sequence of 3 for 6 that began with her fourth delivery that Kathryn Bryce cut to Norris at gully for 31.

Having made an attractive 29 off 34 balls, Prendergast fell lbw sweeping at Morris, as did Lucy Higham for 4.

Hannah Jones returned to take her competition-leading 22nd wicket when Kirstie Gordon drove to Eve Jones at extra cover for 4 before Morris ran through the rest of The Blaze line-up in spectacular style bowling Ella Claridge for 6, having Grace Ballinger lbw for 6 and Cassidy McCarthy caught for 8 with The Blaze losing their last seven wickets for 62 runs.

It was Ballinger who did the early damage with an impressive spell of left-arm swing that returned figures of 4 for 13 to destroy the Thunder top order, having Eve Jones caught at mid-off for 0, Alice Clarke caught at cover for 8 followed by Morris (10) and Dani Collins (0) bowled in the space of three deliveries.

But having completed seven overs Ballinger limped off injured to be replaced by Prendergast who struck immediately with her sixth delivery which Seren Smale cut savagely but straight to Kirk at point for 13 with the Thunder innings in disarray at 41 for 5 after 15 overs.

Ellie Threlkeld pulled a short ball from Prendergast to Higham at deep backward square for 10, Carter was bowled by McCarthy for 11 before Grace Johnson holed out to Kirk off Groves for 27 as Thunder continued to struggle.

Ballinger returned in time to see Groves trap Graham lbw for 5 but a defiant last-wicket partnership of 50 - the highest of the Thunder innings - between Norris, who hit three sixes in a List A career-best 53 not out off 56 balls, and Hannah Jones, who finally fell to Kathryn Bryce for 17, held up The Blaze who eventually wrapped up victory with 26 balls to spare.
