Stephanie Nampiina struck the tournament's first half-century to power the Victoria Pearls to a 14-run win over the United States at Entebbe Cricket Ground on Thursday.
The opener anchored Uganda's innings with 53 off 51 balls as the hosts posted 105 for six after being put in to bat.
Captain Janet Mbabazi and Asumin Akurut then shared six wickets to bowl out the USA for 91 and seal a place in Saturday's final.
Earlier in the day, Rwanda stunned Namibia by four wickets after Ruth Uwimana and Alice Ikuzwe claimed three wickets each to dismiss the visitors for just 58.
Namibia will now face the United States in the third-place playoff at 9:30 AM on Saturday before Uganda take on Rwanda in the final at 2:00 PM.
The argument doing the rounds in Entebbe is whether the Pearls' middle order has enough firepower to chase down a big total in the final.
