Santner’s mind-boggling effort was witnessed during the last ball of the 14th over when pacer Lockie Ferguson bowled a short delivery. In an attempt to play a pull shot, Shahidi got the leading edge. An alert Santner ran backward, dived, and grabbed a one-handed stunner to show Shahidi the way back to the pavilion.
New Zealand thrashed Afghanistan, who defeated England in their previous outing, by 149 runs.
Glenn Phillips, Tom Latham, and Will Young all scored half-centuries and benefitted from dropped catches to score a fighting 288-6.

The Black Caps then ran through Afghanistan, who had shocked defending champions England last time out, for just 139 in 34.4 overs.
The victory gives New Zealand, runners-up at the last two World Cups, a fourth victory in as many games and comfortably on course for the semi-finals.
Santner, who claimed 3-39 in the match, completed 100 wickets in his 98th ODI.
