Speaking after securing their semifinals, Ng'iya coach Ambala said they have now shifted their attention to the knockout stages.
"The girls are playing really well and I am happy so far our strategies are working and tactics are destroying our teams. The girls are hungry, shooting the ball well and defending well. All we need to do is play even better in the knock out stage," said Ambala.
Ng'iya are in Group B alongside Rangala Girls, Nyamira Girls and Lwak Girls.
