What do you think of the rain-affected practice match between Zimbabwe and New Zealand?
http://www.espncricinfo.com/icc-cricket-world-cup-2015/engine/match/806119.html
NZ were 157/7 after 30.1 overs with only Ronchi, Elliot, Nathan McCullum&Mills the only ones left who can do something with the bat.
Seems the trick against most teams by the minnows will be spin&medium pace. 5 wickets were taken by medium pace, and 2 by spin.
14 overs from by far the slowest of the lot got ZIm 3 wickets for under 4 overs at most with the leggie under 5.
So if we meet them in the knockouts, I reckon an attack of Farhaan, Philander, Abbott, Tahir, Phangiso&Duminy should do the trick.
