I really don't understand why Prior isn't in the ODI team.
Indeed, Keiswetter is the better choice in T20 where he can just swing at everything but his inability to rotate the strike effectively is too big a blocker on 50overs.
Hopefully Root can get a big score though, even if we lose this a big debut score from a very talented youngster will be a great positive to take away.
For what it's worth I think we'll fall short, eithe rby giving wickets away chasing the runs or by not getting the rate up, Our only chance is for this pair to post 50-60 each, at least.
