Southern Vipers will be looking to make it two wins from two in the Rachael Heyhoe Flint Trophy on Bank Holiday Monday after beating Sunrisers at The Cloudfm County Ground on Saturday.
Danni Wyatt was the star of the show in Chelmsford, hitting an effortless 66 as Charlotte Edwards' side chased down a target of 203 with 14 overs to spare.
Wyatt's fellow Sussex Women teammate, Paige Scholfield had earlier shone with the ball, taking 3-33 as the Sunrisers were restricted to a below-par total in their inaugural competitive match.
The Vipers, who are captained by Georgia Adams, will now be hoping to make it consecutive victories when they face Western Storm in Bristol later today (Monday 31 August).

After the victory in Chelmsford, Wyatt said: "We are really delighted with the win.
"I think everyone turned up today which is what Charlotte Edwards spoke about last night.
“We spoke about partnerships being crucial and we got going with a hundred partnership with my fellow Sussex player Georgia Adams.
“I felt alright out there. The ball did a bit early on as it always does. It rained much of the batting innings which was quite difficult but it was an outstanding batting wicket here at Chelmsford.
“I just went out there and tried to hit the bad balls and defend the good ones.
“Paige trained really hard this winter. Tournaments like this are really important for people like her and Georgia Adams to push their cases forward for England.”
