Central Sparks 233 (Campbell 68, Freeborn 67, Norris 4-42) beat Thunder 204 (Smale 94, George 3-57) by 29 runs
Central Sparks resumed their Rachael Heyhoe Flint Trophy programme in solid style with a 29-run victory over struggling Thunder at New Road, Worcester.
The defeat leaves bottom-of-the-table Thunder still looking for their first 50-over win of the season but Sparks will move forward with their sights still very much on going all the way in the competition.
Thunder skipper Eleanor Threlkeld won the toss and chose to field and her decision was quickly vindicated by the removal of both Sparks openers in 20 balls. Bethan Ellis was bowled through the gate by an inswinging yorker from Mahika Gaur and Norris struck a big blow when she hit Eve Jones' off stump.
When Erin Burns lifted Gaur to cover, Sparks were in trouble at 27 for 3, but Freeborn and Campbell organised a revival with a well-constructed stand of 129 in 26 overs. Campbell counter-attacked effectively, hitting nine fours in a near run-a-ball innings, before she missed a pull at Norris and was superbly stumped by Threlkeld.
The left-armer secured her third wicket next ball when Davina Perrin was adjudged lbw and Sparks' loss of momentum was heightened when Laura Jackson floated one inside Freeborn's attempted cut and bowled her.
Charis Pavely restored some impetus with 33 from 36 balls, a cameo which transpired to be crucial, but became Norris's fourth victim when she lifted to mid-wicket.
Thunder's reply took an early hit when Naomi Dattani was bowled for a 12-ball duck by a nicely-flighted ball from Georgia Davis. Fi Morris skied Grace Potts into the deep but Smale and Deandra Dottin added 50 in ten overs before the latter missed an attempt to turn Ria Fackrell to leg and fell lbw. Burns then turned one inside Threlkeld's attempted leg-glance to win another lbw decision.
Danielle Collins helped Smale add 52 in ten overs but both fell in five balls. Collins lifted Ellis to mid off and Smale, six runs short of a thoroughly-deserved maiden century, miscued Katie George to mid off. That left the Thunder lower order with a tall task - to find 72 from 11 overs - and despite a perky 22 off 29 balls from Norris it was beyond them.
