The 18-year Logtenberg was vice-captain for the team that was to tour Pakistan for the qualifiers in November. However, unrest in Pakistan saw the tournament being postponed; subsequently, the ICC decided to shift the matches to South Africa.
Now Cricket South Africa (CSA) has confirmed to Cricinfo that Logtenberg, one of two players nominated by CSA for the ICC Women's Cricketer of the Year award in 2007, has opted to stop playing cricket in order to pursue other sports. Allrounder Alicia Smith replaces Logtenberg in the 14-member squad, while Claire Terblanche will be the deputy to captain Cri-zelda Brits.
Logtenberg burst on the scene with an impressive 74 on her Test debut in 2003, when she was just 14. She was named Women's Cricketer of the Year at the South African Cricket Awards in 2006.
South Africa are one of the favourites to qualify from the tournament, where the top two sides go through to join the major nations who will contest the World Cup in Australia in 2009. South Africa are in the same group as Bermuda, Netherlands and Papua New Guinea.
The qualifiers will be held from February 18 to 24.
