Northern Superchargers have retained Katie Levick, Adil Rashid, David Willey ahead of the Hundred's belated launch in 2021, while England academy batting allrounder Hollie Armitage has become the first player to move teams in the women's competition.

The eight men's teams in the ECB's new 100-ball competition have until January to negotiate with players they wish to retain from the squad they selected in October 2019, while in the women's tournament, players can opt to roll their contracts over to 2021 or negotiate with other teams if they wish to do so.

Armitage, who was contracted to the Oval Invincibles for the 2020 season before its postponement due to the Covid-19 pandemic, was born in Huddersfield and played for the Leeds-based Diamonds side in the inaugural Rachael Heyhoe Flint Trophy. She joins Lauren Winfield-Hill and legspinner Levick in the women's squad.

"I love being up North - there's no better place to be playing cricket and I can't wait to get started," Armitage said. "There's been a lot of publicity around the Hundred, and I think it will be great - both on and off the field. I expect the competition to be central to women's cricket really taking off in this country."

Rashid and Willey were picked as the Superchargers' local icon players in the men's competition before the draft last year, and will join Ben Stokes in the squad.

"With myself, Ben and David already confirmed we're looking to build a really strong side for 2021 and hopefully we can have a successful first season," Rashid said.
