Central Sparks 246 for 8 (Pavely 57*, Wong 50, Davidson-Richards 3-46) beat South East Stars 225 (Blinkhorn-Jones 77, Davidson-Richards 48, George 3-30) by 21 runs
Eve Jones, Sparks' leading batter in the competition, was soon out caught behind off Ryana MacDonald-Gay, the first of three catches for wicketkeeper Kira Chathli. In-form Abbey Freeborn also nicked MacDonald-Gay behind, and with Davidson-Richards striking two further blows Sparks stumbled to 61 for 4.
George holed out soon afterwards only for a no-ball to be called for a waist-high full toss and the batter made good of the reprieve with three stylish fours in her 31, raising a 50-partnerhip with opener Bethan Ellis who swept to good effect.
The pair fell in the space of seven balls, George pinned lbw on the back foot by Dani Gregory, while Ellis (42) played one sweep too many against Stars' skipper Bryony Smith.
At 121 for 6 Sparks needed just that - a spark and in fact found two as Pavely and Wong hit the reset button.
Pavely, showing great maturity, played a straight drive back past Gregory before pulling the same bowler to the fence at square leg. Wong played second fiddle for a while before unable to contain her attacking intent any longer - she sent one six into the scoreboard and another clean out the ground as Sparks posted a challenging total.
Inspired by her batting exploits, Wong should have had an early wicket when finding the edge of Chathli's bat, but wicketkeeper Freeborn could only parry the chance away to her right. Wong's response was to take the fielder's out of the equation and uproot Chathli's off-stump.
The England quick soon appealed again for a catch behind against Stars' skipper Bryony Smith, not answered in the affirmative, but from the very next ball Ami Campbell plucked one out of the sky at wide mid-off to send the home skipper packing for a duck.
Alexa Stonehouse (29) briefly threatened only to fall to a catch on the fence by George and Jones pulled off another blinder at slip as Jemima Spence came and went, Davis the successful bowler on both occasions.
Paige Scholfield with two centuries and more than 300 runs in the tournament was another not to last long, bowled through the gate by Australian all-rounder Erin Burns and at 94 for 5 Stars' hopes looked slim.
Davidson-Richards and Blinkhorn-Jones dug in, surviving several vociferous appeals to punish the odd bad ball when it came to raise a 50-partnership and bring the runs required under 100.
The impressive George returned to remove both Davidson-Richards, caught in the deep and Kalea Moore, but Blinkhorn-Jones stood firm, twice dispatching the returning Wong to the fence as she raced to 50.
Macdonald-Gay proved a good foil in a stand of 51 to leave the game in the balance, but she was bowled by Davis and when Blinkhorn-Jones holed out at cover the game was up.
