Cameroon booked their place in the semi-finals of the African Women's Championship in Namibia after beating Algeria 2-0.
Deborah Enganamouit scored both goals, striking one in each half, to give the Indomitable Lionesses all three points.
The result means Cameroon are guaranteed to finish in the top two in Group B, joining record six-time champions Nigeria in the last four.
Ghana and South Africa drew 1-1 in the day's other Group B match.
Banyana Banyana opened the scoring in the 18th minute when Shiwe Nogwanya capitalised on a fumble by the Ghana keeper as she failed to hold the ball from Mamello Makhabane's free-kick.
Ghana levelled the score in injury time at the end of the first half as Elizabeth Cudjoe connected well with a cross from their captain Leticia Zikpi to put the ball past.
Nompumelelo Nyandeni was voted Player of the Match for Banyana Banyana a fitting way for her to celebrate winning her 100th cap.
Saturday's final group matches see South Africa taking on Algeria while at the same time Ghana will face Cameroon.
South Africa and Ghana know only a win will do if they are to have any chance of advancing to the semi-finals.
The top three finishers will all qualify for next year's World Cup in Canada.
