It was a fine effort from England's young seam-and-spin combination, especially on such a tame wicket in Napier.

BBC: England poised for series victory

The partnership passed 50 before Malinga and Muralitharan began to turn the screw, the seam-spin combination slowing the run-rate before Muralitharan coaxed Porterfield (31) into edging behind with an attempted cut.
