Georgia Redmayne and Emma Jones led South East Stars to a sixth victory in the Charlotte Edwards Cup as they comfortably beat Sunrisers by 19 runs at The Oval on Duckworth-Lewis-Stern.
The pair shared 57 in 35 balls to help Stars post 153-4 after losing the toss in a game reduced to 18 overs per side after rain.
Danielle Gregory then took two wickets in three balls to leave Sunrisers struggling badly at 43-5 after eight overs of the chase.
Grace Scrivens kept the pursuit above water with 62 not out in 48 balls but the ballooning asking rate proved too much and the visitors were 111-5 after 15.5 overs before rain returned to end the match early.
Stars stay second in the table, a place at Finals Day already secured, with Sunrisers in seventh, their play-off hopes having already been over.
