Herald cricket writer Andrew Alderson provides three observations from the second day of the second test between New Zealand and England.
1. New Zealand review to dismiss Alastair Cook
Like the second innings at Lord's, a bowling review of Cook was upheld, this time for a Mark Craig lbw. To the naked eye as Cook swept, umpire Ravi's decision looked sound, but captain Brendon McCullum was right to trust Craig's instincts. The ball was spinning back to hit the top of middle.
The delivery stymied England's flow at 177. They scored three runs in the next five overs and the parsimony largely extended until the arrival of the second new ball after which England lost three wickets for 17.
