USA won the toss and elected to field! That is utter foolishness. Only a team that has a very strong batting line-up could take such a decision. What made Staple feel he could chase a Kiwi total?
Zimbabwe too seem to have lost their mind. If Aus,NZ,Srl,Eng or even Win elect to chase it would be fine.
But USA,Zim,Ken and Ban have only one way to win. Elect to bat and put a average(220-230) total and then use your meagre bowling resources to take some early wickets. Maintain the pressure and keep taking wickets at regular intervals. Even this way they have only a 50:50 chance but otherwise I say 0.0001:99.999
