I hope Burrage, Boulter and Christie were at least invited. Team spirit is a thing and I reckon there'd be an even better vibe and less anxiety with that enlarged gang. Plus some of them are going to be the future.
Rather too early for Jodie, time will tell re her in the future. Katie B yes a decent shout and Freya possibly, though her form recently has not been good and she needs to sort that out.
I think there is at least as much case for a smaller more clearly focussed group of just one above the named team of 4 and that appears to be what they have with just Katie Swan.
It's Hannah( 2 FedCup appearances ), the analyst, Gill as was mentioned above ( 4 appearances) and Millie Mirkovic , physio ( 1 appearance), the lady on the far right must be a 1st timer as I don't recognise her.
