This is great to see from Mashrafe. The last time he bowled with this much "zip" was probably agianst India in the World Cup. And Mash was a little extra motivated that day because of the comments made by Kumble earlier about touring Bangladesh with such short rest after the World Cup.
I think that the comments made by some of the members of the New Zeland media really fired Mash up and that was evident in his bowling spell specially with the new ball. Great stuff Mash
