NZ Black Sox beat Australia to win the World Series, remain NZ's most successful sporting team

New Zealand have been crowned the kings of softball after overcoming Australia in the final of the World Softball Championships in Canada.

The Black Sox fought back from a 3-2 deficit in the seventh inning after a grand slam homerun by Joel Evans edged them ahead 6-4, a lead which they never relinquished.

It’s the seventh time New Zealand have claimed the title of World Champions, with this their 10th straight berth in the finals.
