Australia skipper Pat Cummins bowled Kane Williamson in the final hour of play on the second day of the second test in Christchurch on Saturday, just as the master batsman threatened an innings that would put New Zealand on top.

After 14 wickets fell on day one and seven more before tea, Williamson and Tom Latham had hit the pause button on a frenetic match with a partnership of 105 that erased Australia's first-innings lead and put the home side 17 runs ahead.
