Birmingham 172 for 6 (Kalis 52, K Bryce 4-21) beat The Blaze 147 for 8 (Beaumont 44, Arlott 3-33) by 25 runs
Warwickshire handed The Blaze their first defeat of the Women's Vitality Blast campaign, by 25 runs, in a clash of two of the competition's front-runners at Edgbaston.
Warwickshire's total of 172 for 6 was built upon strong contributions from their top three with
Sterre Kalis hitting 54 (41 balls), Meg Austin 39 (30) and Davina Perrin 25 (18). Thereafter runs came less freely as
Kathryn Bryce dismissed those three on the way to an excellent 4 for 21.
The Blaze replied with a scrappy 147 for 8.
Tammy Beaumont hit 44 off 29 but the rest of the powerful batting line-up misfired against the home side's excellent and varied attack led by the pace of
Em Arlott, with 3 for 33 and the spin of
Millie Taylor (2 for 23).
Warwickshire chose to bat and were given a strong foundation by openers Austin and Perrin who added 59 in 40 balls. Both then fell to the Bryce sisters - stumped by Sarah off Kathryn. In each case it was excellent glovework by the wicketkeeper as Perrin was lured down the pitch and Bryce (S) did well to take a ball that bounced, and then Austin missed an attempted cut and lifted her back foot just momentarily but long enough for Bryce to pounce.
Kalis added another polished half-century to the one she lodged for Netherlands against USA in Utrecht eight days ago but the rest came and went fleetingly.
Laura Harris tried to slog-sweep from outside off stump and skied Kirstie Gordon to midwicket. Pavely, Warwickshire's match-winner two days earlier, lifted Grace Ballinger to long-on.
Kathryn Bryce returned to have Kalis caught at mid-off and Nat Wraith pouched at extra cover as Warwickshire came in with a decent but by no means daunting total on a good batting pitch.
The Blaze soon lost former Warwickshire batter, Marie Kelly, who pulled Issy Wong to deep square. Beaumont, who hit seven fours and a six, and Kathyn Bryce added 49 from 48 balls but then fell in successive overs, caught in the deep off Taylor and Georgia Davis respectively. When Heather Graham chipped Hannah Baker to midwicket, three wickets had fallen for 12 runs in 18 balls and the required rate had climbed above ten per over.
As the equation came down to 64 from the last five overs, the Blaze needed a huge over but it never came. Georgia Elwiss sought six over midwicket off England pace bowler Arlott but was well-caught by Perrin just inside the rope. Ella Claridge lifted Taylor straight and Perrin was under that one too as Warwickshire's diverse and disciplined attack extinguished the Blaze chase.
