Black Queens beat South Africa 1-0 in their final friendly game ahead of the upcoming 2018 Africa Women's Cup of Nations on Sunday.
Ghana wrapped up their preparations for the competition which kicks off on November 17 with a win over South Africa at the newly refurbished Accra Sports Stadium for the three-week tournament.
Samira Suleman header in the 21st minute gave coach Bashir Hayford his first win ahead of the tournament following a shocking 3-2 defeat to Zambia and a 1-1 stalemate with Kenya in their three pre-tournament friendlies.
She headed home a corner from the left at the near post to beat goalkeeper Kaylin Swart.
Both sides displayed glimpses of good football subsequently but failed to turn the scoring opportunities into goals.
The Black Queens nearly got the second of the encounter but Elizabeth Addo's brilliant free-kick from the edge of the box was saved by the crossbar in the 66th minute.
Ghana came close to getting the second goal after Portia Boakye's effort missed the goalposts by a whisker following a cross from Alice Kusi.
The flagship women's tournament in Africa starts next Saturday.
Ghana will play Algeria in the opener on Saturday at the same whilst South Africa take on reigning champions Nigeria in their opening fixture at the Cape Coast stadium on Sunday.
