The first signings of the open market stage in The Hundred women’s competition have been confirmed with all-rounder Naomi Dattani one of four players announced to be joining Trent Rockets.

Dattani, previously of London Spirit, is joined at Trent Bridge by Josie Groves, Emma Jones and Alexa Stonehouse.

Groves is one of three players from The Blaze to have their place confirmed among the latest raft of signings, with Marie Kelly heading to Northern Superchargers and Sarah Bryce set to represent Welsh Fire.

Across the eight teams, 26 signings have been announced with Groves and Stonehouse two of the six stars of England Women’s U19 World Cup team among the list, as well as Australian all-rounder Erin Burns, WPL break-out star Tara Norris and Scottish leg-spinner Abtaha Maqsood.
