James Anderson validated his elevation to top spot in the world Test bowling rankings with a lethal opening spell as England took full control of the second Test against New Zealand on Saturday.

Veteran seamer Anderson snared 3-37, sending the Black Caps crashing to 138-7 when rain forced an early end to day two in Wellington, after England declared their first innings at 435-8. Spinner Jack Leach also took three scalps, leaving New Zealand staring at a 297-run deficit with three days remaining.
