"It's an important series," Clarke said.
"Any one-day game now leading up to the World Cup is crucial to us as a team.
"The more success we can have leading into that tournament the better, so hopefully a full strength team that's ready to play against two very good teams in tough conditions."
Clarke is probably just being polite, but it is true that Zimbabwe tend to play quite well at home and have comfortably beaten less-than-full-strength teams in the past (like India in 2010 and South Africa XI in 2012).
