Former South Africa Women's World Cup cricketer Elriesa Theunissen-Fourie and her child were killed in a car crash this weekend.
The fatal accident occurred in the northwestern mining town of Stilfontein, a police spokesman told AFP.
Theunissen-Fourie, 25, represented South Africa in three ODIs and one T20I. She was a part of the 2013 World Cup squad as well.
"This is a dreadful tragedy in the true sense of that word," said Cricket South Africa (CSA) chief executive Thabang Moroe. "This is devastating news for all of us.
"Elriesa did so much for the community in which she lived and gave excellent service both as a national player and in the work she did at grassroots level.
"On behalf of the CSA family, I extend our deepest sympathy to her husband, her family, friends and all her cricketing colleagues."
