Skipper Marie Kelly led the way with a fourth half-century of the competition as The Blaze reinforced their position at the top of the table in the Metro Bank One Day Cup with a four-wicket victory over Yorkshire at Chesterfield.

Yorkshire - one of only two teams to beat The Blaze this season - were no match this time, dismissed for 150 in 42.3 overs.

Kelly helped The Blaze overhaul their target with almost 20 overs to spare, picking up a bonus point for good measure to go with four for the win. She was aided by England Under-19 international Prisha Thanawala, who made an attractive 30.

Seamer Charley Phillips - the competition’s leading wicket-taker -  took three for 29, although the stand-out bowling performance was delivered by 18-year-old left-arm spinner Maria Andrews, who sent down four maidens in her 10 overs, finishing with two wickets for just 20 runs.

Having chosen to bat on a green surface, Yorkshire suffered a double early setback and rapidly stumbled to 60 for five.

The visitors elected to bat on a green surface but were blown away by the Blaze's bowling attack. They suffered a double early setback before stumbling to 60-5.

Charlie Knott struck first, and Phillips followed with another two balls later before Knott dealt Yorkshire a major blow by bowling Australian compatriot Jess Jonassen off an inside edge.

Andrews, who has impressed since making her debut a couple weeks ago, trapped Erin Thomas in front before a lovely flighted delivery saw Rebecca Duckworth stumped.

In between, Thanawala swooped in with a bullet run out to again scupper Yorkshire's hopes.

Georgia Elwiss removed Beth Langston and Ines Blackwell in consecutive overs and Phillips bagged her second and third, leaving The Blaze needing 151.

In reply, The Blaze seemed intent on knocking off the target as quickly as possible, perhaps mindful of the soaring temperature as well as a potential bonus point. A powerplay worth 59 runs cost three wickets.

Langston had Tammy Beaumont and Knott leg before on the back foot before bowling Elwiss through the gate.

Kelly and Michaela Kirk added 42 before drinks again brought a wicket, Kirk smartly caught behind off Glenn for 18.

But 19-year-old Thanawala looked at ease from the outset, ramping her first two balls for four against England legspinner Glenn and went on to make an accomplished 30 off 36 balls.

In a late twist, she was run out and Kelly was leg before to Blackwell in consecutive balls but it was too little, too late for Yorkshire.
