MAIA Bouchier led the way with a career-best 93 as Southern Vipers thrashed South East Stars by 113 runs in the Charlotte Edwards Cup.

The opener needed just 55 balls to make the second-highest score in this season’s competition as Vipers posted 179 for five.

South East Stars were bowled out for just 66, the second-lowest completed total in this season’s competition.

Speaking after the win, Bouchier said: "I'm just very happy to get that score and for us to get that win.

"I have been working on my mental processes, to be a bit more positive in my outlook instead of going into my shell.

"Today I got away with a couple of edges and I told myself as long as I stayed in, I could catch up.

"I struggled a little bit at the start and then Jones came on and I got those boundaries and it pushed on my innings.

"We're super happy, it's a great win for us and will give us some momentum for finals day."

Southern Vipers' Charlie Dean picked up three wickets for five, Linsey Smith took three for 12 and Charli Knott two for 11 as nine of the wickets fell to spin.

A curious powerplay saw Vipers reach 50 for one with Bouchier hitting 32 off those runs from just seven balls.

She hit the first five deliveries of the fourth over from Emily Jones to the boundary before twice lofting Tash Farrant over the ropes in the sixth.

The 25 year old reached her fifty off 27 balls during a productive stand of 76 in nine overs with skipper Georgia Adams.

Adams made the most of being put down by Alexa Stonehouse on 13 as she contributed 39 before an attempted ramp was held at backward point.

It gave Farrant a second wicket after she had picked up Danni Wyatt in the second over with a slower ball that Wyatt chipped to mid-on.

Bouchier seemed to be making serene progress to a hundred but she missed a reverse sweep to give Stars’ skipper Bryony Smith a wicket with her second ball.

Freya Kemp swelled the total with 30 off 14 balls at the end and Stars’ miserable chase never recovered after they lost three wickets in the powerplay.

Bryony Smith looked like she meant business, taking four boundaries off Freya Davies in the opening over of the reply.

But after she was stumped for 22 trying to hit slow left-armer Linsey Smith over the top in the second over the innings nosedived. The next highest contribution was Stonehouse’s nine.

Paige Schofield missed a sweep, Smith picked up Tarrant and Kalea Moore before Dean added to Stars’ pain by bowling Alice Davidson-Richards and Jones with successive balls.

There was no way back for Stars from 44 for 6 and off-spinner Knott finished things off in the 14th over.

The Vipers will now look to defend their Charlotte Edwards Cup title on Saturday at Derby's County Ground in finals day.
