“I feel these games are really big for us,” Edwards told Sky Sports after England started her and Sciver-Brunt’s reign with a comprehensive T20 series clean sweep against West Indies.
“We’ve got nine games before the World Cup starts, so a lot of this is about us getting the right balance of team.
“Nat’s not bowling this series and she’s probably not going to bowl most of the summer. We want to make sure she’s fit and firing for the World Cup.
“Her workloads will start in a few weeks. It gives her an opportunity to look at other options, so we know we’ve got that balance if and when Nat comes back.”
England face West Indies in three one-day internationals starting at Derby on Friday.
Batter Alice Capsey has been added to the squad as cover for former captain Heather Knight, who suffered a hamstring injury during England’s win in the third T20.
Knight’s participation in the rest of the series will be confirmed after she has a scan on Tuesday.
Fast bowler Lauren Filer also joins the squad, having fully recovered from a knee injury.
The West Indies series is followed by a T20 and an ODI series against India across June and July, but Edwards and Sciver-Brunt’s first major assignment comes in the autumn, with India hosting the 50-over World Cup.
