Warwickshire defeated Lancashire by four wickets at Southport in a match reduced to 42 overs per side due to rain.
Chasing a target of 227, Charis Pavely, the leading run scorer in the competition, made 63 – the top score in the match – before a brilliant seventh-wicket stand of 75 off 66 balls between Mary Taylor (42 not out) and Nat Wraith (34 not out) clinched victory with nine balls to spare as Warwickshire finished on 230-6.
Lancashire made 226-9 after being put in to bat with the bulk of the runs coming from skipper Ellie Threlkeld (39) and Maddie Penna (38) during a third-wicket partnership of 83.
Kate Cross marshalled the lower order in making 34 off 33 balls, while Taylor returned her best Warwickshire bowling figures of 3-47 as Phoebe Brett (2-35) and Georgia Davis (2-38) took two wickets apiece.
The result leaves Lancashire second from bottom in the table with two wins from seven games, while Warwickshire moved into the top four with their third win of the campaign.
