South Africa advanced to the semi-final of the 2019 Cosafa U20 Women's Cup after a hard-fought 1-0 win over Namibia on Saturday.
After a 3-0 win over Zimbabwe, Basetsana were aiming to keep up their fine run against the Gladiators at the Gelvandale Stadium.
Shahida Jacobs' strike 10 minutes into the encounter was all Simphiwe Dludlu's side required to gain the maximum points.
The win takes the hosts to the top of Group A with six points from two games and earns them passage to the knockout stage.
