Davis, who made her England debut last month on the white ball tour of Ireland – has been one of the country’s top wicket takers in recent seasons.
The former police officer, who signed for Central Sparks in 2020, was the leading bowler in the 2023 Rachael Heyhoe Flint Trophy with 27 wickets.
She made an impressive start to her international career by taking 2/19 in the second ODI against Ireland in September.
