Dutch international Sterre Kalis scored a half century in the final of the Rachael Heyhoe Flint Trophy but it was in vain as her Northern Diamonds side lost to Southern Vipers by 39 runs.

The 21 year-old, who has also represented Essex and Queensland, top scored with 55 as they chased Vipers' total of 231.

She hit eight boundaries in her 75-ball knock, but despite her best efforts Diamonds fell 38 runs adrift.

It was a strange season for Kalis, who started with three ducks, but finished in style with three consecutive half centuries!
