Lancashire 163 for 4 (E Jones 57) beat Yorkshire 160 for 7 (Campbell 47, Weerappuli 3-13) by six wickets

Weerappuli, 16, has broken into Lancashire’s first team during this competition having impressed in age-group and Academy cricket. She has grown up in Yorkshire.

This excellent career-best included the key wicket of opener Ami Campbell for 47 off 21 balls as winless Yorkshire slipped from 79 for one in the seventh over to 160 for seven.

Thunder openers Meg Lanning with 34 off 15 balls and Eve Jones 57 off 38 led an exhilarating but stress-free chase as Lancashire completed their second win in eight games with 17 balls remaining. Their slim quarter-final hopes are alive, but Yorkshire’s are all but over after a seventh defeat.

Left-handed Campbell attacked at the fast-scoring Clifton Park.

She crashed two sixes as 24 came from the bowling of Kate Cross in the sixth over, Yorkshire’s score moving to 74 for one.

But Thunder hit back with wickets in successive overs for emerging spinners Weerappuli and Sophie Morris – 81 for three in the eighth. Wily Weerappuli had a sweeping Campbell caught at backward square-leg off a top-edge.

Tara Norris had home captain Lauren Winfield-Hill caught in the deep as the Red Rose fightback continued, Yorkshire reaching halfway at 97 for four.

From there, the White Rose struggled as Weerappuli bowled Sterre Kalis for 22 and trapped a sweeping Olivia Thomas lbw.

All of a sudden, Yorkshire were scrambling to reach 150, which they managed to do. But Lancashire definitely had the advantage heading into a chase which started in similar fashion to how Yorkshire’s had.

Australian overseas Lanning initially attacked.

Lanning had a scare on eight when she pulled Hannah Rainey out to deep square-leg, the ball parried over the rope for six by Claudie Cooper.

Lanning hit a straight six and three fours off Cooper’s off-spin as 19 came from the fourth over. But she fell caught behind cutting at the end of it, with the score 46 for one.

Last year’s double winners Lancashire are having a poor season, though they are a much more experienced side than Yorkshire, who are in the midst of their first Tier 1 campaign. And it showed.

The powerplay scores were almost identical at 78 for one and 74 for one. But Lancashire never looked like letting this slip. And they pressed on.

Left-handed Jones, who hit seven fours and two sixes in all, drilled Beth Langston’s seam down the ground for six shortly before reaching her fifty off 31 balls.

By the time she got there, it felt like game over at 96 for one in the 10th over.

Jones dominated a second-wicket partnership of 68 with Emma Lamb, who contributed 22.

And not even their departures to the seam of Rainey and Jess Woolston – 116 for three in the 13th over – could derail Thunder, for whom new England Test wicketkeeper-batter Ellie Threlkeld finished 28 not out.
