EXETER, England : Teenage wing Braxton Sorensen-McGee scored two tries as defending champions New Zealand survived a first-half scare to defeat South Africa 46-17 in their Women’s Rugby World Cup quarter-final at Sandy Park on Saturday. South Africa starved New Zealand of the ball in the opening period and used their forward power to go to the break level at 10-10 but once the Black Ferns gained more possession they ran their opponents ragged and scored eight tries in all.
