The table-toppers are beaten for the second time in a week after four wickets apiece for Emily Arlott and Charis Pavely
New Road: Southern Vipers 183, Central Sparks 184-3 - Central Sparks won by seven wickets
Central Sparks turned the Rachael Heyhoe Flint table upside down by thrashing league leaders Southern Vipers by seven wickets at Worcester.
Sparks took full advantage of Vipers' depletion by international calls to add another emphatic victory to their five-wicket Charlotte Edwards Cup win over Georgia Adams' side at New Road in June.
Put in, Vipers were bowled out for 183 in 48.4 overs as Georgia Elwiss (64 not out, 86 balls) fought a lone battle against a potent attack led by Emily Arlott (4 for 15) and Charis Pavely 4 for 31).
Sparks then cruised to 184 for 3 with 64 balls to spare after a polished opening stand of 95 between Eve Jones (54, 38) and Ami Campbell (48, 63) gave the pursuit a perfect platform.
