Jodi Grewcock and Flo Miller have been awarded their first professional contracts with Sunrisers.
The pair join Eva Gray, Kelly Castle, Amara Carr, Jo Gardner, Cordelia Griffiths, Mady Villiers, Abtaha Maqsood and Grace Scrivens on full-time deals.
Miller made her senior debut for the regional side in August 2021, away at Northern Diamonds, and has chalked up nine appearances to date.
At county level, she has been a regular for Northamptonshire since 2019.

"Being offered my first professional contract is so exciting, and I can't wait to get going this season. It's also great to start my career with Jodi alongside me, since we've been playing together at Northants for years now, so to begin this journey together is special," Miller said.
Grewcock, meanwhile, made her Sunrisers debut at the back end of the 2022 season, scoring 35 runs against Lightning in the Rachael Heyhoe Flint Trophy. She followed that performance with five runs and figures of 2 for 27 against Central Sparks. Like Miller, she is a product of Northamptonshire's pathway.
She said: "I'm buzzing. As a young, ambitious player, I'm so excited to be given this opportunity. I really enjoy the coaching-playing group here and I'm eager to progress and contribute to Sunrisers success."
Head coach, Andy Tennant, added: "We are delighted to add these two high-potential young home-grown athletes to our full-time professional staff.
"Both Flo and Jodi have shown great potential with the bat, and it will be exciting to see how far their games can develop within a full-time professional programme."
