Striker Mohammed Anas scored to help Polokwane City progressed to the MTN8 semi-finals after a 2-0 win over defending champions Cape Town City on Saturday afternoon.
Anas curled in an opener in the 25th minute after capitalizing on poor defending.
Polokwane earned a penalty after a one-two between Anas and Nku forced Mobara to trip the latter on the hour mark.
But goalkeeper Peter Leeuwenburgh palmed away Sibusiso Mbonani’s spot-kick.
In the 83rd minute, substitute Charlton Mashumba produced a neat finish seven minutes from time with a curling strike from just inside the box to the bottom corner.
