South East Stars secured qualification in the Rachael Heyhoe-Flint Trophy in the most emphatic style with a 152-run victory over Central Sparks in a winner-takes-all clash at Edgbaston.
Stars captain Bryony Smith led from the front with a blistering 97 (81 balls, ten fours, three sixes) and, supported by Kira Chathli (61, 92 balls) powered her team to a hefty 283 for seven.
Spinners Hannah Baker (two for 46) and Georgia Davis (two for 47) imposed some mid-innings control for Sparks.
Sparks would have qualified themselves if they had chased down the target but their reply never took flight.
Only Maddy Green (39, 48 balls) passed 20 against a disciplined attack led by Alice Davidson-Richards (three for 20) and Ryana MacDonald-Gay (three for 27).
Put in, Stars lost an early wicket when Alexa Stonehouse skied a slog at Emily Arlott, but it was an isolated success with the new ball for the bowlers as Chathli and Smith added 125 in 21 overs for the second wicket.
After Chathli chipped Baker to mid-off and Smith fell three short of a deserved century when she top-edged Davis to mid-wicket, the innings lost momentum in the middle before a late fillip came from Chloe Hill (34, 24) and Maddie Blinkhorn-Jones (24, 26).
They batted intelligently to 57 in 48 balls for the eighth wicket to lift the total from around par to imposing.
Under some scoreboard pressure, Sparks needed a strong platform but lost both openers in three balls from McDonald-Gay.
Eve Jones was strangled down the leg side and then Bethan Ellis edged a lovely outswinger to wicketkeeper Chathli.
Green and Abi Freeborn counter-attacked with brief success to take the score to 50 in ten overs but the departure of Freeborn, lbw to Paige Schofield, triggered a collapse.
Davidson-Richards removed Ami Campbell, caught at deep mid-wicket, and Katie George who top-edged a scoop and was well caught by Chathli running back towards fine leg.
When Green, having hit six fours, was bowled by Danielle Gregory, it was 102 for seven. Sparks needed something miraculous from their tail but Stars closed the game out without alarms.
