The West Indies Women are in the semi-finals of the 2022 ICC Women's World Cup after Lady Luck worked in their favour on Saturday night.

The West Indies Women, on seven points from their seven games, following no-result against South Africa on Wednesday, March 23, needed either Bangladesh to defeat England or South Africa to defeat India for them to advance.

England crushed Bangladesh by 100 runs earlier Saturday, which meant that the West Indies Women were dependent on a positive result from the South Africa versus India encounter.

The situation looked grim when India posted 274-7 in their 50 overs thanks to half centuries of 71 from Smriti Mandhana, 53 from Shafali Verma, 68 from Captain Mithali Raj as well as Harmanpreet Kaur's 48.

However, Laura Woolvardt smashed 80, Laura Goodall scored 49 and Mignon du Preez an unbeaten 52 as South Africa scored 275-7, the winning run coming off the last ball of the match.

The South African victory set off wild celebrations among the West Indies Women, whose members had gathered to watch the match.

They will now face unbeaten Australia in the semi-final on Tuesday.
